What This Concept Is Saying
In the Buddhist doctrinal system, 有漏 (sāsrava, "with outflows") does not mean a container has cracked and is leaking liquid; rather, it is a concept that reveals with extreme precision the operating mechanism and pathological root of all things in the world.
漏 (āsrava, "outflow") literally means seepage, flowing forth, leaking. It is compared to defilements leaking like water from a broken pot, constantly seeping outward, preventing the mind-consciousness from remaining focused and settled; it is also like a wound oozing pus, a sore seeping blood, continually generating filth and plunging the life-system into prolonged inflammation and suffering. 有漏 means "carrying the seepage of defilements; able to generate defilements and clinging."
Definition in one sentence: it refers to the mundane conditioned dharmas (有為法, saṃskṛta-dharma) that accompany defilements, generate craving and aversion, and lead to the turning of birth-and-death (生死流轉) — the fetters that practitioners must cut off.
Within the entire path of liberation, 有漏 corresponds to the interwoven state of the noble truth of suffering (苦諦, duḥkha-satya) and the noble truth of origination (集諦, samudaya-satya). It is the underlying attribute of all experienced phenomena (五陰/五蘊, pañcaskandha, the five aggregates; 十二入/十二處, dvādaśāyatana, the twelve sense bases; 十八界, aṣṭādaśa-dhātu, the eighteen elements) before our lives attain liberation. To thoroughly understand 有漏, we must dissect it from the four core dimensions clearly established in the classical scriptures:
1. Operating Mechanism: Generating Craving and Aversion, Arising Together with Clinging
In the 雜阿含經 (*Saṃyuktāgama*), the most direct characteristic of 有漏法 (sāsrava-dharma, "dharmas with outflows") is that they "generate craving (愛, greed) and aversion (恚, hatred)" [5107]. As long as our sensory experience (eye, form, eye-consciousness, eye-contact, and even the pleasant, unpleasant, and neutral feelings that arise from them) remains within the mundane sphere, it is 有漏法 [5598].
The scriptures often pair 有漏 with 取 (upādāna, "clinging"), as in "form is with outflows and is clinging" [5107]. When we encounter agreeable or disagreeable situations in daily life, if we have not cultivated 身念處 (kāyānupasyanā, "contemplation of the body") and the mind lacks the wisdom of liberation, we will delight in and attach to favorable circumstances (craving) and loathe and reject adverse ones (aversion) [11244]. This interweaving of craving and aversion not only causes the defilements of the moment to leak forth, but also gives 天魔波旬 (Māra Pāpīyas, "Māra the Evil One" — external demonic obstacles and internal defilements) a gateway to enter: unarisen obstacles of sorrow, grief, distress, and affliction arise, and already-arisen hindrances grow even greater [5430, 11244].
2. The Nature of Arising and Ceasing: Arising and Ceasing Moment by Moment, the Substance Is Not Real (Inversion)
In the 大般涅槃經 (*Mahāparinirvāṇa-sūtra*), the underlying structure of 有漏法 is revealed as "生生" (birth after birth) or "外法生生" (external dharmas born again and again), meaning they are in the violent flux of "arising and ceasing moment by moment" [9369].
More critically, the scripture explicitly asserts: "一切有漏即是顛倒" — all that is with outflows is precisely inversion [9724]. Why is it called inversion? Because the sensory cognition of ordinary beings (such as "the five consciousnesses of sentient beings") belongs to the sphere of 有漏; through thought, deluded conceptual inversion (顛倒, viparyāsa) arises, grasping the impermanent as permanent, suffering as happiness, non-self as self, and the impure as pure [9724]. The experience established on such inverted cognition is not real in substance and only ever increases the "various outflows"; therefore it can never be called "pure holy conduct" (清淨梵行) [9724].
3. Extension of the Structure: The Three Outflows (欲漏、有漏、無明漏)
The scriptures systematically classify the outflows, primarily as the "three outflows" (三有漏, or simply 三漏):
* 欲漏 (kāma-āsrava, "outflow of desire"): all defilements of the desire realm (欲界, kāmadhātu) and greedy clinging to sensory objects (form, sound, smell, taste, touch) [8011, 9385, 9712]. * 有漏 (bhava-āsrava, "outflow of existence"): here 有 (bhava) means existence, survival. It specifically refers to all defilements of the form realm (色界, rūpadhātu) and formless realm (無色界, ārūpyadhātu) — deep clinging to higher meditative states, mental existence, or the continuation of individual life [8011, 9385, 9712]. * 無明漏 (avidyā-āsrava, "outflow of ignorance"): the fundamental ignorance of the three realms — ignorance of the true nature of dharmas (the four noble truths, dependent origination, non-self). Ignorance is the source and root of all outflows; it gives rise to all outflows of desire and outflows of existence [8011, 9385, 9712].
4. Adjudication of Special Dharmas: "Supreme Worldly Dharma" and the Five Consciousnesses
The classical scriptures and treatises draw the boundaries of 有漏 with great depth — far beyond a crude nominal gloss:
* 眾生五識 (the five consciousnesses of sentient beings): eye, ear, nose, tongue, and body consciousness — all belong to 有漏 and are inverted, because they extremely easily trigger subsequent deluded clinging and increase the outflows [9724]. * 世第一法 (laukikāgradharma, "supreme worldly dharma"): the highest stage of mundane practice within the sphere of 有漏 (the moment immediately before entering the supramundane path of seeing). Although 世第一法 nominally still belongs to 有漏法, because its entire mind is oriented toward 無漏 (anāsrava, "without outflows") and it is the direct antecedent of the correct view of 無漏, the scriptures specifically adjudicate it as "性非顛倒" — its nature is not inverted [9724]. Yet since it is in essence just a single thought of the mundane mind, unable to generate sustained continuity of thought, it still cannot be called "pure holy conduct" [9724]. This extremely fine-grained adjudication demonstrates how rigorously Buddhism guards the boundary between mundane and supramundane dharmas.
5. The Path of Extinction: From the "Seven Methods of Cutting Off Outflows" to the Exhaustion of Outflows and the Unconditioned
In the 中阿含經 (*Madhyamāgama*), the Buddha gives an extremely systematic and practicable "七斷漏法" — seven methods for cutting off the outflows — showing how to stop the leaking of energy step by step:
1. Cutting off by seeing (從見斷): truly knowing the four noble truths, cutting off the three fetters of personality-view (身見, satkāya-dṛṣṭi), attachment to precepts and practices (戒取, śīlavrata-parāmārśa), and doubt (疑, vicikitsā) — cutting off the leaking at the level of thought and cognition [2420, 2421]. 2. Cutting off by guarding (從護斷): guarding the six sense faculties of eye, ear, nose, tongue, body, and mind; cultivating contemplations such as the contemplation of impurity (不淨觀, aśubhā-bhāvanā), so that defilements do not enter through the senses [2421]. 3. Cutting off by avoidance (從離斷): staying away from wild beasts and dangerous places, from evil companions and unfavorable environments [2421, 2422]. 4. Cutting off by use (從用斷): using clothing, food, shelter, medicine, and other necessities of life only moderately — to ward off cold and heat, to allay hunger and thirst, and to support the holy life — never for pride, adornment, or pleasure [2422]. 5. Cutting off by endurance (從忍斷): patiently enduring bodily and mental suffering such as hunger and thirst, heat and cold, mosquitoes and flies, harsh words and beatings, and illness [2422]. 6. Cutting off by removal (從除斷): when thoughts of desire, thoughts of aversion, or thoughts of harm arise, immediately becoming aware and removing, cutting off, and abandoning them [2422]. 7. Cutting off by contemplation (從思惟斷): contemplating the seven factors of awakening (七覺支, sapta bodhyaṅga), based on renunciation, based on desirelessness, based on cessation, tending toward liberation [2422].
Through the gradual washing and refining of these seven methods (like sifting sand to find gold, progressively eliminating coarse dirt, then less coarse dirt, then fine dirt) [15421], the practitioner finally attains "the mind is liberated from the outflow of desire; the mind is liberated from the outflows of existence and ignorance" [4121, 4553]. At this point one truly knows "empty of the outflow of desire, empty of the outflow of existence, empty of the outflow of ignorance"; the inversions of the world are completely extinguished, and only the subtle physical fatigue of "this body with its six sense bases, life still present" remains. This is the ultimate "exhaustion of outflows, without outflows, unconditioned, liberation of mind" (漏盡、無漏、無為、心解脫) [4553].
A Walkthrough in Daily Life
To keep 有漏 from becoming an abstract Buddhist term, let us use the most familiar contemporary scenes — scrolling through your phone late at night and coping with urgent work demands — to conduct a "walkthrough" of our life-state and see how 有漏 leaks our energy without our noticing.
Scene One: Late-Night Scrolling Through Short Videos / Social Media
* Sensory contact (eye, form, eye-consciousness, eye-contact): You lie in bed, finger gliding across the screen. The visual sense receives striking images (form); eye-consciousness and eye-contact occur. * Correcting a misconception: Many people think the act of "scrolling" itself is the defilement. In fact, the light and images on the screen and your eyes seeing them are pure sensory presentation. But as long as your cognition remains in the mundane sphere, this entire mechanism is a platform of 有漏 [5598]. * Craving and aversion arise (outflow of desire): When you scroll to a lavishly decorated mansion video, envy and a sense of lack arise in you (craving); next you scroll to an absurd news item and intense anger and rejection arise (aversion). This is precisely what the 雜阿含經 calls "generating craving and aversion" [5107]. You have developed delight and attachment, aversion and loathing, in sensory stimulation, without cultivating 身念處 [11244]. * Clinging and inversion (outflow of ignorance and clinging): The algorithm captures your emotional fluctuations and begins pushing more content that makes you anxious or agitated. You think "just five more minutes and I'll relax" — this is inversion (mistaking stimulation that brings feverish bitter retribution for happiness) [9724]. You have not actually rested; rather, "unarisen obstacles of sorrow, grief, distress, and affliction with outflows arise, and already-arisen ones grow even greater" [5430]. * Walkthrough summary: This is the intersection of the "outflow of desire" and the "outflow of ignorance." The phone itself is a mere object, but through improper attention you have torn a gap in your mind-consciousness, and mental energy leaks out from here endlessly, leaving you groggy and hollow when you wake the next morning.
Scene Two: "Existential Anxiety" and Performance Reviews in the Workplace
* From "cutting off by use" to 有漏: The company is selecting the annual outstanding employee, or there is a risk of layoffs. Your mind begins to shake violently. * Correcting a misconception: Some think "working hard" is 有漏 and "lying flat" is 無漏. This is a gross misreading. The "seven methods of cutting off outflows" makes it clear: if the necessities of life or work resources are used moderately merely "to ward off cold and heat, to allay hunger and thirst, and to support the holy life," that is the 無漏 wisdom of "cutting off by use" [2422]. * The eruption of the "outflow of existence": When your work is no longer about sustaining livelihood or actualizing value, but becomes "I must prove I am better than others," "I cannot lose this title," this triggers 有漏 (bhava-āsrava, the outflow of existence) [8011, 9385]. You have developed extreme clinging to your "sense of self-existence" (有, bhava). * Māra enters through the gap: Because you fear losing your position (sense of existence), you grow suspicious at a single frown from your boss, defensive toward colleagues' normal cooperation (aversion), and lie awake at night from anxiety. This is precisely what the 雜阿含經 describes: facing disagreeable sense objects, unwholesome dharmas arise, and 天魔波旬 enters through the gap, subjecting one to the images of fame and profit, making one a slave to the "cause of birth, aging, sickness, and death" [4493, 11244].
Why Contemporary People Need It
Contemporary society is an "ultra-有漏" society. The core logic of modern commercial civilization and information technology is almost entirely built on "how to precisely stimulate people's 有漏 attributes."
1. Perceiving the truth of "mental energy hemorrhage" Contemporary people universally feel "mentally exhausted," "spiritually drained," or "burned out." Modern psychology often attributes this to stress and poor energy management. But examined through the lens of 有漏, you will find: energy is not being used up — it is being "leaked" away. When we generate craving toward information streams, aversion toward differing opinions, and terror and self-clinging toward future uncertainty (ignorance), the blood vessels of the mind-consciousness are constantly bleeding. Understanding 有漏, you can see through it at a glance: every violent fluctuation of emotion, every unbridled pursuit of pleasure, is a severe "leakage" of life energy.
2. Reading the "inversion" of the AI and algorithm age Contemporary algorithms (short videos, information feeds, targeted advertising) are in essence "有漏 amplifiers." By analyzing your "five consciousnesses of sentient beings" and preferences (which are themselves 有漏 and inverted) [9724], the algorithm continuously feeds your craving and aversion, keeping you immersed in the "birth after birth" feedback loop of desire. (Note: The algorithm analogy is vivid, but one must clearly recognize that algorithms are merely statistical data-recommendation mechanisms, whereas the Buddhist 有漏 involves the storehouse consciousness (阿賴耶識, ālayavijñāna), the flow of karma (業力), and the activity of deep mental factors (心所, caitta). Science and technology can explain the physical pathways of information transmission, but cannot replace the thorough awakening to the true nature of mind.)
3. Redefining "success" and "purity" The success that contemporary people pursue (wealth, status, fame) — in the Buddhist view, as long as it is accompanied by self-clinging and defilements, no matter its scale, is essentially 有漏法. It is impermanent, arising and ceasing moment by moment [9369]. Understanding 有漏 can inject a dose of cooling medicine into the feverish modern person: not all mundane effort is meaningless, but without establishing the correct view of 無漏, all the stacking of mundane things will ultimately fail to escape the fate of "feverish bitter retribution" [4493]. It reminds us that while pursuing worldly achievement, we must reserve a space of mind for cultivating the 無漏 practices of "guarding the six sense faculties" and "cutting off unwholesome thoughts."
Common Misreadings and Clarifications
Misreading One: 有漏 means "bad things" or "sinful things," and 無漏 means "good things."
* Clarification: Buddhism is not a dualistic moral judgment. 有漏 is a factual and pathological description — it refers to "a mechanism that accompanies defilements and generates fetters and bitter fruits." More importantly, the scriptures contain extremely rigorous stage divisions, such as 世第一法 [9724]. 世第一法 belongs by nature to the mundane sphere (有漏), but because it is wholly oriented toward liberation and is the key step toward the 無漏 path of seeing, the scriptures specifically point out that it is "性非顛倒" — its nature is not inverted [9724]. This shows that within 有漏法 there are also wholesome dharmas and practices that "tend toward 無漏" (such as "cutting off pride through pride, cutting off craving through craving") [6571, 6572]. One cannot crudely equate 有漏 with evil or guilt.
Misreading Two: As long as I don't think about bad things and keep my mind calm, my state is "無漏."
* Clarification: This is a severe narrowing of "無明漏" and 有漏. Many meditators can achieve a mind temporarily free of desire (no outflow of desire), or even enter deep meditative states (such as form-realm and formless-realm concentrations). But the scriptures clearly state that all defilements of the form realm and formless realm belong to 有漏 (bhava-āsrava, the outflow of existence) [9385, 9712]. If you develop a hidden clinging to this state of purity and tranquility, or if the fundamental ignorance (ignorance of the true nature of self and dharmas) has not been broken through by insight, you remain under the dominion of the "outflow of ignorance." True 無漏 requires truly knowing the four noble truths, thoroughly cutting off the three fetters (身見、戒取、疑), and completely dismantling the root of ignorance [2420, 2421].
Misreading Three: Since the five aggregates, six sense bases, and other mundane experiences are all 有漏, liberation means completely destroying the body and senses.
* Clarification: This is a classic annihilationist view (斷滅見, uccheda-dṛṣṭi). In the 中阿含經, when the practitioner has fully realized "the mind is liberated from the outflow of desire, the mind is liberated from the outflows of existence and ignorance" and attained ultimate exhaustion of outflows, what is the state? The scripture says: truly knowing "empty of the outflow of desire, empty of the outflow of existence, empty of the outflow of ignorance," the defilements are exhausted, and "only the subtle fatigue of this body with its six sense bases, life still present, remains" [4553]. The noble one (聖者, ārya) still has a body; the eye, ear, nose, tongue, body, and mind (six sense bases) still exist and function normally — only the mind no longer combines with defilements, no longer generates craving, aversion, and clinging [5107]. What is cut off is the "outflow" (the fetter of defilement), not the senses and life itself. The Tathāgata's (如來) form body, free from defilements, is the truly constant, unchanging, ultimately pure [9710].
