What This Concept Is About
Let us begin with a very ordinary experience.
A person is ridiculed in public the first time they speak at a meeting. The event ends, the meeting room empties, and those words have long since vanished—yet months later, the moment he prepares to speak, his body tenses up first, and the thought quickly surfaces: "Better not say anything." The past has not been stored in the mind intact like an object, nor has it simply been reduced to zero. It has left behind a tendency: when conditions are suitable, a similar response can occur again.
The Yogācāra school explains this kind of causal continuity—where something has "already disappeared, yet can still influence what comes later"—through the model of "perfuming–seeding" (*vāsanā-bīja*). But what it describes goes far beyond mere psychological habit, nor is it simply what modern people call the "subconscious." It attempts to answer a fundamental question that runs through birth-and-death and the entire path of practice: How do psycho-physical activities, which arise and cease in each moment, leave behind after-effects? Karma has already passed—why can it still produce results later? Afflictions are not presently active—why do they arise again when conditions are met? And why is it possible for hearing, reflecting on, and cultivating the Dharma to gradually transform the trajectory of a life?
In one sentence: A perfuming-seed is a functional difference (*kāritra-viśeṣa*) formed in the continuation of the *ālayavijñāna* when a perfuming factor (*śakti-dharma*) and the perfumed consciousness (*bhājya-vijñāna*) correspond to each other, arising together and ceasing together; this potential awaits the confluence of various conditions and can bring about results corresponding to its own nature.
Every layer here is indispensable.
First, "perfuming" is not the insertion of a tiny physical entity into the mind.
The *Mahāyānasaṃgraha-bhāṣya* (Asaṅga's commentary, with Vasubandhu's and Sthiramati's sub-commentaries) states explicitly that a seed is not a separate entity residing within the *ālayavijñāna*, nor can it be said to be wholly indistinguishable from it. It is the functional difference possessed by the *ālayavijñāna* at the moment of its arising, by virtue of which it is "capable of giving rise to that dharma." It is like a piece of cloth that has been perfumed by incense and can subsequently emit fragrance; we need not imagine that a miniature flower is hidden inside the cloth—we need only acknowledge that the state of the cloth has undergone a change sufficient to produce subsequent effects.
The treatise uses the analogy of sesame seeds (*tilāḥ*) kept together with fragrant flowers: the flowers and the sesame exist simultaneously and act upon each other simultaneously; after the flowers are removed, the sesame still carries the fragrance. Correspondingly, in the mind, when afflictions such as craving are active, they can perfume the mind such that the cause for future craving arises; and hearing much true Dharma can likewise perfume the mind, forming the cause for recollection, understanding, and even the arising of the supramundane mind.
But this analogy only aids understanding; it must not be reversed into regarding seeds as material fragrance. Seeds are functional differences within causal continuity—they are not particles that can be extracted from the mind.
Second, the perfuming factor and the perfumed consciousness must "arise together and cease together" (*sahabhāva-nirodha*).
The perfuming factor consists of the mind and mental factors that are presently occurring and capable of leaving an influence; the perfumed consciousness is the *ālayavijñāna*, which is able to receive and maintain that influence. The two must correspond simultaneously: at the very moment an affliction arises, it perfumes the root consciousness; when wholesome thoughts, learning, discernment, and practice occur, they likewise perfume corresponding potentials in that same moment. It is not the case that after a previous moment has ceased, it then travels across time to perfume a later moment.
The *Mahāyānasaṃgraha-bhāṣya* therefore does not take the six evolving consciousnesses themselves as the ultimate support for maintaining all perfuming. The eye, ear, nose, tongue, body, and mind consciousnesses each have different supports, objects, and attentions; they are also interrupted and alternating; and two successive moments do not exist simultaneously. If one merely said that the previous moment hands something over to an already-changed later moment, it would be difficult to explain how perfuming could span the interruptions of consciousness, sleep, unconscious states (*asaṃjñi-samāpatti*), and even an entire lifetime. Therefore, the Yogācāra school establishes the continuously flowing *ālayavijñāna* as the perfumed consciousness and the locus where seeds accumulate.
This does not mean the *ālayavijñāna* is an eternal soul. It itself also arises and ceases moment by moment—it is just that its continuity is unbroken; it is a stream of causes and conditions, not a permanent subject. The so-called "storage" is likewise only an expedient expression; it should not be imagined as a static warehouse.
Third, a qualified "perfumed consciousness" has four conditions.
The *Mahāyānasaṃgraha-bhāṣya* (Sthiramati's sub-commentary) summarizes them as:
- **"Stability" (*sthira*)**: Not eternally unchanging, but continuously stable enough to maintain the causal continuity of perfuming and seeds.
- **"Neutral" (*avyākṛta*)**: Its own nature is not fixed as wholesome or unwholesome, so it can equally receive the perfuming of wholesome, unwholesome, and neutral dharmas. The *ālayavijñāna*, as the maturation-consciousness (*vipāka-vijñāna*), has the nature of the undefiled-neutral (*anivṛtāvyākṛta*).
- **"Perfumable" (*bhāvya*)**: Capable of being influenced, such that functional differences can unfold and combine within the continuum; if it were an absolutely unchanging permanent dharma, it could not be perfumed.
- **"Corresponding with the perfuming factor" (*sahakāri*)**: The perfumed and the perfuming must be simultaneous and co-located, related as neither identical nor separate, arising together and ceasing together.
The six evolving consciousnesses cannot stably satisfy these conditions; the *ālayavijñāna* is therefore established as the perfumed consciousness. This also shows that perfuming is not a loose notion of "whatever is repeated enough counts"—it is a rigorous causal structure.
Fourth, seeds have six characteristics.
According to the summary in the *Mahāyānasaṃgraha-bhāṣya*, seeds possess six aspects:
- **"Momentary cessation" (*kṣaṇikā*)**: A seed is not a permanent entity. It arises and ceases moment by moment in dependence on the continuum of consciousness; only through the similarity and continuity of successive moments can it serve as the cause for producing a result.
- **"Simultaneous with its result" (*phalasahabhū*)**: When a seed produces its result, the cause and effect must have a relationship of simultaneous functioning; it is not that something long since absolutely extinguished suddenly produces a result out of nothing.
- **"Continuously following" (*sadā anuvartate*)**: From the time of being perfumed until maturation, the function of the seed follows along with the continuum of the *ālayavijñāna*; when conditions have not yet been met, this does not mean it has already disappeared.
- **"Determinate" (*niyata*)**: The causal nature of seeds has a corresponding direction; the potentials of the wholesome, the unwholesome, and specific cognitive activities do not produce results arbitrarily and without pattern.
- **"Awaiting various conditions" (*pratyayāpekṣī*)**: Having a seed does not mean the result must occur immediately. It must still await such conditions as the object, environment, bodily state, attention, auxiliary conditions, or obstacles.
- **"Only producing its own result" (*svaphalajanaka*)**: A seed can only give rise to a result corresponding to its own nature; it cannot produce just anything. The perfuming of craving can foster the manifestation of craving; the perfuming of extensive hearing can support recollection and understanding; the two do not become one thing merely because they are both called "seeds."
"Result of its own class" (*svajātiya-phala*) therefore does not mean the result is an exact replica of the cause in appearance, but rather that cause and effect have a determinate correspondence in nature and function. The seed left by a single humiliation may later manifest as withdrawal, hostility, or excessive defensiveness; the specific form is also influenced by other seeds and present conditions—it should not be understood mechanically as a video replay.
Fifth, seeds and manifest activities (*pravṛtti*) mutually intensify each other.
Manifest activities such as the six consciousnesses arise from seeds in the *ālayavijñāna* together with various conditions; when manifest activities arise, they in turn perfume the *ālayavijñāna*, causing existing tendencies to grow, weaken, transform, or perfume new functional differences. The Yogācāra school commonly uses the formulation "seeds give rise to manifest activities; manifest activities perfume seeds" to describe this cycle.
The *Mahāyānasaṃgraha-bhāṣya* (Sthiramati's sub-commentary) further uses the analogies of a lamp flame and wick, and of a sheaf of reeds standing in mutual support: the *ālayavijñāna* and the defiled manifest activities are not each independent, but are mutually causal and mutually supporting. One should not imagine the *ālayavijñāna* as a pre-existing, complete hard drive into which the six consciousnesses merely write files; the "hard drive itself" is also situated within the causal nexus of being perfumed, holding seeds, and generating manifest activities.
Sixth, internal seeds (*adhyātma-bīja*) and external seeds (*bahirdhā-bīja*) must not be conflated.
External seeds such as grains and sesame can sometimes be explained through external growth conditions, without needing to say that the grain itself has undergone perfuming in the psychological sense; internal seeds, by contrast, are necessarily formed through perfuming. The *Mahāyānasaṃgraha-bhāṣya* accordingly emphasizes: if there were completely no perfuming from hearing and yet wisdom from hearing, wisdom from reflection, and their corresponding results could arise without cause, this would fall into "obtaining without having done" (*akṛta-prāpti*); if one had already studied and acted, yet no function remained, then later one should incur "loss of what has been done" (*kṛta-vipraṇāśa*). Both destroy the intelligibility of causality.
The Yogācāra school further states that "external seeds have internal seeds as their condition" and "external seeds are not separate from internal seeds": the external seeds we experience and their enjoyment do not transcend the conditions of sentient beings' karmic seeds and consciousness-transformation. This is not denying rice seeds, soil, and sunlight on the everyday level; rather, within Yogācāra epistemology and karmic-result theory, it indicates that "the external environment as experienced and enjoyed by sentient beings" cannot be established entirely apart from the internal stream of consciousness and karmic perfuming.
Seventh, perfuming-seeds have both a defiled aspect and an aspect that leads to liberation.
Xuanzang's translation of Vasubandhu's commentary lists three important types of perfuming:
- **"Perfuming-seeds of verbal designation" (*vyavahāra-vāsanā-bīja*)**: This refers not only to spoken language, but includes the cognitive structures formed through names, concepts, and discriminative activity; these become the causes for the manifestation of consciousnesses such as the body, the basis of the body, the experiencer, the experienced, the agent of experiencing, time, number, location, and speech.
- **"Perfuming-seeds of the view of self" (*satkāya-dṛṣṭi-vāsanā-bīja*)**: These support grasping the contents of the continuum as "I" and "other," forming the consciousness of self–other distinction. This is not an ordinary self-introduction, but a more fundamental subjectivizing appropriation.
- **"Perfuming-seeds of the life-process factors" (*bhava-aṅga-vāsanā-bīja*)**: Connected with wholesome and unwholesome karma and the limbs of birth-and-death, these become the causes for the manifestation of consciousnesses of fortunate destinies, unfortunate destinies, death, and rebirth.
These three are not three boxes containing different contents, but three angles—verbal designation, the structure of self-grasping, and the continuity of karmic results—through which the world of false discrimination is shown to be continuously constructed.
Defiled seeds are also called "coarseness" or "weightiness" (*dauṣṭhulya*); Paramārtha's translation uses terms like "excess-aggregation" (*過聚性*) and "density" (*稠密*), emphasizing their accumulation, difficulty of dissolution, and resistance to breaking. "Coarseness" does not merely mean that emotions are uncomfortable; it means that the potential of afflictions and karma prevents the mind from being at ease, causing similar grasping and suffering-results to be reborn ceaselessly.
However, if there were only defiled perfuming, liberation could not be established. The *Mahāyānasaṃgraha-bhāṣya* (Sthiramati's sub-commentary) specifically explains "hearing-perfuming" (*śrutavāsanā*): through the correct teaching of the true Dharma, one hears without error; based on correct hearing, correct understanding arises; then through reflection and cultivation, a seed capable of giving rise to the supramundane uncontaminated mind is formed. It abides in the maturation-consciousness, combining and flowing with it like water mixed with milk, yet it is not the defiled nature of the *ālayavijñāna* itself, but rather the pure seed that counteracts the *ālayavijñāna*. As hearing, reflection, and cultivation grow continuously, the perfuming can progress from the lower grade to the middle and upper grades, hence it is also called "the seed of the Dharma-body" and "the seed of the supramundane mind."
This is precisely the place of perfuming-seeds in the entire path of liberation: on the one hand, it explains why ignorance, self-grasping, afflictions, and karma do not automatically end when a single thought disappears; on the other hand, it explains why morality, concentration, and wisdom must be cultivated repeatedly, and why right view can gradually transform from "understanding one sentence of doctrine" into a power that changes the continuation of a life.
Liberation is not a matter of pressing one correct idea down on top of an incorrect one, but rather, through hearing, reflection, cultivation, and non-conceptual wisdom, causing defiled seeds to lose their conditions for growth, to be counteracted, and even to cease producing results; while simultaneously causing pure seeds to grow and mature, transforming the entire causal structure of the consciousness-stream. What non-conceptual wisdom removes is not a bag of substantial seeds, but the functional power by which false discrimination and defiled dharmas are regenerated.
A Walk-Through in Daily Life
Let us examine a complete scenario of "scrolling through the phone after work."
You have just finished a long day of overtime, your body is tired, and upon returning home you intended to rest for ten minutes—but before you realize it, you have opened a short-video app. The first video brings a bit of novelty, the second triggers comparison, the third makes you angry, and the fourth promises something even more stimulating. When you come to your senses, a long time has passed; you are even more exhausted, yet still unwilling to put the phone down.
First step: Conditions converge; it is not that a single seed issues a command on its own.
Fatigue, the phone being right at hand, notifications lighting up, being alone, habitual usage patterns formed in the past, the platform's recommendation mechanism, and the present motivation to escape pressure—all of these together serve as conditions. Seeds must "await various conditions" in order to become manifest. Therefore, the Buddhist view of causality is not fatalism: having a potential does not mean it is destined to happen exactly as before; changing the environment and conditions is itself part of practice and mind-training.
The algorithm here can amplify temptations, but it cannot be said to be "seeds" in your mind. The algorithm is an external condition and a mechanism of information selection; perfuming-seeds are, as the Yogācāra school describes, internal functional differences established in dependence on the continuum of the *ālayavijñāna*. The two can cooperate: the platform more accurately pushes content you are prone to react to, and your repeated clicks further strengthen the platform's model, as well as your own tendencies. But this is only an instructive structural analogy; it does not mean that Buddhist seed theory has been proven by computer science.
Second step: Seeds meet conditions and give rise to corresponding manifest activities.
When an image appears, the eye-consciousness and its associated mental factors are activated; the mind-consciousness then recognizes the content, evaluates it as beneficial or harmful, and may give rise to craving, anger, envy, anxiety, or avoidance. The easiest mistake here is to directly equate "seeds" with emotions that have already appeared. The craving, anger, and comparison presently occurring are manifest activities; the potential function that makes these reactions likely to occur again is what is called a seed.
Nor can one directly declare a particular neural circuit to be the *ālayavijñāna* or a seed. Neuroscience can study habit formation, reward learning, attentional bias, and memory consolidation, but these theories are still developing, and their objects of study differ from the Yogācāra concern with karma, birth-and-death continuity, and liberation theory. The two can be carefully compared, but they cannot be substituted for one another, and it cannot be said that science has already proven the existence of the *ālayavijñāna*.
Third step: The manifest activity and the root consciousness arise together and cease together; perfuming occurs in that very moment.
It is not that you only package and archive the experience after you finish scrolling. Each manifest activity of "boredom—tap—brief relief," at the moment it occurs, flows together with the *ālayavijñāna* and serves as a perfuming factor; the *ālayavijñāna*, as the perfumed consciousness, forms or strengthens the corresponding functional difference in its continuum. This is "arising together and ceasing together."
If a similar process recurs repeatedly, the force of the seed may grow. The next time you feel even slightly tired, your hand is already reaching for the phone. But "repeated perfuming" does not mean that only multiple repetitions count as perfuming: a single intense experience can also form a significant influence; repeated occurrence, however, better illustrates the strengthening of the continuum.
Fourth step: Seeds "continuously follow" along, but they are not a static file.
The next day in a meeting, you are not scrolling through videos, and that tendency does not appear as a significant manifest activity; but this does not mean the relevant potential does not exist. It follows along with the continuum of consciousness; when evening comes, alone and tired, with the phone lighting up, the conditions reconverge and the corresponding manifest activity may arise again.
People commonly understand this step as "a video recording stored in the subconscious." This is still too reifying. What the Yogācāra school describes is the continuity of a function capable of producing results; it does not require past experiences to be permanently preserved as complete images. What matters for the concept of a seed is that it can evoke subsequent reactions.
Fifth step: The result is not an exact copy of the original; rather, it is "determinate" and "only produces its own result."
The perfuming of escaping pressure tends to evoke further escape, the seeking of immediate stimulation, and corresponding psycho-physical activities; it does not, without cause, give rise to wisdom entirely unrelated to it. But how long one scrolls on a given evening, what one watches, and whether craving or anger arises—these still depend on other seeds and present conditions. Causality has direction, but it is not a single-track mechanical determination.
Sixth step: New manifest activities in turn perfume seeds, forming a cycle.
A single tap brings momentary relief; the relief strengthens the tendency to "tap when pressure arises"; more similar manifest activities then perfume functional differences in the root consciousness. Seeds give rise to manifest activities, and manifest activities perfume seeds—so a habit increasingly looks like "this is just who I am."
But the Yogācāra school precisely does not require one to acknowledge a fixed "self." The so-called "I just can't control it" is often a misapprehension of a dependent-arising process—one that is conditioned and can be transformed—as an unchangeable self-nature. Seeds are powerful, but they are not a soul, a personality essence, or a sentence of fate.
Seventh step: Practice is not about hating old seeds, but about changing manifest activities and conditions.
You notice your hand reaching for the phone; pause first, recognize "this is fatigue and avoidance presently manifesting"; put the phone far away, weakening the external condition; feel the tightness in the body without immediately chasing stimulation; reflect correctly on the short-lived pleasure and the subsequent fatigue; instead respond to pressure with a walk, a shower, sitting meditation, or talking with family. These are not merely behavioral techniques; they are also reducing the continued perfuming of old manifest activities and giving awareness, restraint, loving-kindness, and wisdom new opportunities for perfuming.
If one further hears the true Dharma, understands impermanence, dependent origination, and selflessness, and then repeatedly reflects on what has been heard and applies it in contemplation, this is not merely developing a "healthy habit." According to Sthiramati's framework, this is the hearing-perfuming gradually growing through hearing, reflection, and cultivation, becoming the seed that counteracts the defiled and leads to the arising of the supramundane mind.
The same structure can also be walked through in intimate relationships.
A partner's late reply to a message is merely an external condition; past experiences of being neglected, the perfuming of the view of self, and the verbal designation "silence means you don't love me" cause anxiety and accusation to become manifest. When accusation occurs, it perfumes a seed for even faster defensiveness the next time; the other person, upon being attacked, also generates their own defensive manifest activities—two streams of consciousness serving as mutual external conditions to each other through words and behavior. If one of them can recognize the feeling, pause the blame, and ask honestly, this is changing the auxiliary conditions and perfuming a different way of responding.
The most common mis-mapping here is to say that "the other person" is one's own karmic illusion, as if all responsibility could be canceled. Yogācāra analysis does not ask one to deny specific harms, power relations, or real-world responsibility; it asks one to see that "what kind of person the other is" as we experience it is always mixed with verbal designation, self-grasping, and existing perfuming. Seeing this is for the sake of responding to reality more accurately—not escaping reality.
Why Contemporary People Need It
First, it gives us a more truthful path between "I'm just naturally like this" and "I can change immediately if I want to."
Seed theory acknowledges the depth of entrenched habits. Anger, people-pleasing, addiction, envy, or self-negation formed over many years will not completely disappear just because one has heard a single principle; the seeds are still present, and when conditions are met they may still become manifest. But it also refuses to reify entrenched habits into an eternal personality: seeds exist in dependence on perfuming and conditions, arise and cease moment by moment, and can be strengthened—and can also be counteracted.
Therefore, practice is neither self-abandonment nor a superstition about willpower. It is patient and precise work on causes and conditions.
Second, it explains why "knowing" is not the same as "being able to do."
A person can know conceptually that anger harms others, yet still explode immediately when provoked. Because the force of a new piece of knowledge may not yet be sufficient to change a response-structure formed by long-term perfuming. Hearing the Dharma is only the starting point; it must be followed by reflection, so that the principle becomes a stable determination; and then by cultivation, so that it is capable of manifesting in real situations.
This also explains why hearing, reflection, and cultivation are not three levels of knowledge accumulation. Hearing gives right view the opportunity to enter the stream of consciousness; reflection allows it to undergo examination, so that it is no longer merely someone else's words; cultivation allows it to arise repeatedly, sufficiently to counteract the original inverted habits. The path is not about hoarding Buddhist information, but about changing which forces arise at critical moments.
Third, it helps us understand algorithmic life without pushing all responsibility onto the algorithm.
Recommendation systems excel at capturing and amplifying existing preferences: the more you stay, the more they push; the more they push, the more easily you stay. This bears resemblance to the cycle of "manifest activity—strengthening—re-manifestation." Seeing this, we place greater importance on environmental design: turning off notifications, reducing temptations, choosing good companions and reliable sources of information—all of these count as adjusting "conditions."
But the Yogācāra school also asks a deeper question: why does a particular stimulus especially capture me? How do I interpret a fleeting feeling as "I absolutely must have this"? What verbal-designation perfuming, self-view perfuming, and craving are operating here? If one only blames the platform, the inner perfuming goes unseen; if one only blames oneself, systemic external conditions are ignored. The vision of dependent origination requires looking at both sides simultaneously.
Fourth, it makes ethics not merely a matter of obeying rules, but of caring for the future continuity of one's mind.
The effect of one harsh word is not limited to hurting others on the spot; it also perfumes, within one's own stream of consciousness, a potential that makes harsh words more likely in the future. One instance of restraint, honesty, or generosity likewise not only produces external results, but makes the corresponding wholesome dharmas more likely to manifest again. The meaning of moral discipline (*śīla*) is therefore not merely "the Buddha said it's not allowed," but protecting oneself and others from allowing certain causes of suffering to grow ever stronger through repeated manifestation.
Of course, this cannot be simplified into "doing good deeds is depositing points in a cosmic bank." Karmic results are not a supernatural bookkeeper dispensing rewards and punishments; rather, the actions of body, speech, and mind form causal forces within the continuity of consciousness, which must await the maturation of complex conditions.
Fifth, it offers a perspective for education, parenting, and relationships that is gentle without being permissive.
A child who lies repeatedly cannot be hastily labeled "he's just bad"; an adult who repeatedly loses control cannot be sealed off with a personality label. Behavior must bear consequences, but one should also continue to ask: what fears, rewards, and relational patterns are causing this manifest activity to be continuously perfumed? What wholesome conditions might allow honesty, stability, and empathy the opportunity to manifest?
This understanding does not cancel responsibility; it shifts responsibility from condemning a personality to changing causes and conditions, stopping erroneous perfuming, and cultivating sustainable wholesome dharmas.
Sixth, it describes liberation as "revolution of the basis" (*āśraya-parāvṛtti*), not merely as temporarily feeling calm.
If afflictions were merely present emotions, then making emotions briefly disappear might seem sufficient. But seed theory points out that when afflictions are not manifest, the corresponding potential may still be flowing along. Therefore, a momentary stillness in meditation does not automatically mean afflictions have been cut off; suppression, distraction, and the absence of triggers can all produce a superficial calm.
What the path of liberation seeks to change is the fundamental support upon which defiled dharmas continuously arise. Through moral discipline, one prevents strong defiled manifestations from repeatedly perfuming; through concentration, one enables the mind to abide and observe; through wisdom, one correctly penetrates the objects of perception, the perceiving subject, and the fact that all dharmas arise in dependence on conditions without fixed self-nature—gradually counteracting self-grasping and false discrimination. The final goal is not for "me" to own a warehouse of more beautiful seeds, but for the fundamental grasping at this "me" itself to be illuminated and broken through.
Perfuming-seeds thus stand at the intersection of dependent origination, karmic results, Yogācāra doctrine, and the theory of liberation: looking backward, they explain how karma and experience leave behind potentials; looking forward, they explain how future dharmas arise in dependence on conditions; looking downward, they explain why saṃsāra has inertia; looking upward, they explain why hearing, reflection, and cultivation can become the causes of the supramundane.
Common Misreadings and Clarifications
One: "Seeds are the subconscious."
Not accurate. Both attempt to explain factors that are not manifest yet can influence behavior, so a limited analogy is possible; but the "unconscious" in modern psychology has a variety of theoretical definitions and typically does not carry the Yogācāra meaning of karmic results, birth-and-death continuity, the *ālayavijñāna*, and supramundane counteraction. Using "subconscious" as an entry-level metaphor is acceptable; drawing an equals sign directly would narrow the concept.
**Two: "The *ālayavijñāna* is a warehouse storing memories."**
This is an expedient imagination, but it easily leads to reification. The *ālayavijñāna* is not a fixed container, and seeds are not data packets arranged inside it. The *ālayavijñāna* itself arises and ceases moment by moment while flowing continuously; seeds are the function-differences capable of generating results within this stream of consciousness. "Storage" is not static preservation, but the causal force within the continuum not yet being lost.
Three: "A seed is a tiny physical entity hidden in the mind."
Sthiramati's commentary has already ruled out this understanding. A seed is neither a separate entity, nor can it be crudely said to be completely identical with the *ālayavijñāna*; it is a functional difference on the *ālayavijñāna* capable of giving rise to corresponding resultant dharmas. Just as when we say a medicine has a healing function, we need not search for a tiny object called "healing function" hidden inside the medicine.
Four: "Perfuming is just habit formation through repetition."
Too narrow. Repetition can indeed strengthen seeds, but the classical definition of perfuming also includes conditions such as the perfuming factor, the perfumed consciousness, correspondence, and simultaneous arising-and-ceasing; its scope also includes afflictions, wholesome and unwholesome karma, verbal designation, self-view, life-process factors, and hearing-reflection-cultivation—not merely daily behavioral habits.
Five: "The previous thought directly perfumes the next thought."
This does not conform to the *Mahāyānasaṃgraha-bhāṣya*'s argument for the basis of perfuming. Two successive moments do not coexist; the six consciousnesses are also interrupted and differentiated; the stable continuity of seeds cannot be explained by one moment perfuming the next. The Yogācāra school therefore establishes the *ālayavijñāna* as the perfumed consciousness and the support for holding seeds.
Six: "Seeds produce results, so everything is already predetermined."
Quite the opposite: among the six characteristics of seeds is "awaiting various conditions." Seeds determine the corresponding direction of cause and effect, but they cannot produce results automatically apart from conditions. Old seeds may meet supportive conditions and grow, may temporarily not manifest due to missing conditions, or may be counteracted by opposing wholesome dharmas, right view, and wisdom. Karmic results have order, but this is not fatalism.
Seven: "'Only producing its own result' means one action produces only one fixed result."
Also not accurate. "Own result" emphasizes the correspondence of causal nature; it does not mean that within a complex life there is a mechanical one-cause-one-effect replication. A single action often simultaneously contains different motivations, objects, and mental factors, and is interwoven with various old seeds and present conditions; the way it matures can be very complex. We cannot arbitrarily deduce, from present circumstances, what someone must have done in the past.
Eight: "Since everything is manifested by one's own seeds, the external world and other people are unreal, and one need not take responsibility."
This mistakes Yogācāra for a flippant subjective idealism. "External seeds are not separate from internal seeds" is a statement within Yogācāra doctrine that the experienced external environment does not transcend consciousness and karmic seeds in its establishment; it does not mean that on the everyday level one can deny the suffering of others, public facts, or the consequences of actions. Precisely because one's own words and actions become external conditions for others, and also re-perfume one's own stream of consciousness, responsibility is all the more weighty.
Nine: "If afflictions do not arise, the seeds have already been cut off."
Not necessarily. The absence of triggers, temporary suppression, or making afflictions non-manifest in meditative absorption does not mean the corresponding seeds have been fundamentally counteracted. Judging one's practice cannot be based only on calm in favorable circumstances; one must also see whether, when confronted with gain and loss, praise and blame, intimacy and distance, grasping still quickly reappears. The classical statements about removing coarseness and excess-aggregation point to a deep transformation of the causes that generate defilement.
Ten: "Listening to a lot of Dharma will naturally bring liberation."
Hearing-perfuming is extremely important, but it must not be understood as play-count or knowledge volume. What Sthiramati's commentary describes is "hearing without error" directed at the true Dharma, and progressing from hearing to reflection, from reflection to cultivation, so that the lower-grade perfuming increases to the middle and upper grades. If hearing only increases conversational material, a sense of superiority, and sectarian rivalry, what gets strengthened in manifestation may instead be verbal designation and self-view.
**Eleven: "Since hearing-perfuming abides in the *ālayavijñāna*, it is the defiled nature of the *ālayavijñāna*."**
Not so. Sthiramati's commentary specifically explains that although hearing-perfuming abides in the maturation-consciousness, flowing together with it like water mixed with milk, it is not the self-nature of the *ālayavijñāna*, but rather its counteracting seed, capable of becoming the cause for the arising of the supramundane uncontaminated mind. This distinction ensures that liberation is not the defiled system merely extending itself unchanged, but that genuine counteraction and transformation of the basis are possible.
Twelve: "Covering negative thoughts with positive ones is purifying the seeds."
This may provide temporary help, but it is not what Buddhism calls liberation. If "I must be positive" still revolves around a self that must be affirmed and must control everything, the perfuming of self-view may not have moved at all. The Buddhist counteraction does not merely replace negative content with positive content; it also observes correctly that all dharmas arise in dependence on conditions, do not abide for even a moment, and have no fixed self-nature that can be grasped—thereby loosening, at the root, the grasping of the perceiver and the perceived.
In the final analysis, what "perfuming-seeds" tells us is not a slogan like "habits determine your life," but two deeper facts: no single arising of a thought ever completely fails to leave a causal after-effect, and no established tendency possesses an eternally unchanging self-nature.
Saṃsāra is heavy because manifest activities continuously perfume seeds, and seeds continuously give rise to manifest activities; liberation is possible because this cycle itself is established in dependence on conditions. Since it is established in dependence on conditions, it can be transformed from the side of conditions. Every time one does not continue to fabricate with craving and anger, every moment of accurate awareness, every instance of correct hearing, reflection, and cultivation—none of these is decorating a fixed "self"; each is changing which dharmas will arise more easily in the future, and ultimately moving toward the transcendence of the entire structure of grasping.
