Refers to sentient beings who lie between those definitely destined toward the good and those definitely destined toward evil—whose nature is as yet undetermined and who easily drift along with causes and conditions.
What This Concept Is About
In the Buddhist comprehensive mapping of sentient beings’ faculties and future trajectories, the “three groups” (三聚, trayo rāśayaḥ) form an extremely crucial classification system. “聚” (rāśi) means gathering or category. The “three groups” classify all sentient beings into three major communities according to the strength of their “definiteness” in moving toward liberation or falling away:
1. 正定聚 (samyaktva-niyata-rāśi, “the group definitely destined for the good”; also 正性定聚): refers to sentient beings who have already established irreversible right faith and right view, or who have already cut off the delusions of views (見惑, darśana-heya) and entered the stage of the noble ones—whose destiny is “definitely oriented toward the good and certain to reach liberation.” 2. 邪定聚 (mithyātva-niyata-rāśi, “the group definitely destined for evil”; also 邪性定聚): refers to sentient beings who have created extremely grave karmic deeds (such as the five uninterrupted deeds, 五無間業, pañcānantarya-karmāṇi), who stubbornly cling to wrong views, and whose destiny is “definitely oriented toward evil and certain to fall into the bad destinies.” 3. 不定聚 (aniyata-rāśi, “the indeterminate group”; also 不定性聚): refers to the vast majority of sentient beings who lie between the above two—having neither established an unshakable cause of liberation nor committed an irrevocable determined evil karma—whose mind, conduct, and future destiny depend entirely on the “conditions encountered.”
To thoroughly understand 不定聚 (aniyata-rāśi), one must, within the overall coordinate system of the path of liberation, unpack its core doctrine into the following four progressive dimensions:
1. Core Attribute: Lack of Definiteness, Easy Drifting with Conditions
“不定” (aniyata, “indeterminate”) is not some independent, fixed quality, but rather a floating state lacking anchorage. The faculties and mind-nature of beings in the indeterminate group have not yet been “set.” Encounter good spiritual friends (善知識, kalyāṇamitra), pure environments, or conditions of the true Dharma, and they can sprout toward the good; encounter evil companions, defiled environments, or the inducement of wrong views, and they will flow downstream and fall. The scriptures point out that because beings of the indeterminate group lack definitive right faith, their life trajectory is in a state of extreme fluctuation and change—“或向于异趣” (may turn toward different realms of rebirth)—possessing great uncertainty.
2. The Buddha’s “Definitive Knowledge”: Insight Within Indeterminacy
For beings of the indeterminate group, with their chaotic, wavering, unpredictable tendencies, ordinary people see chaos and confusion, but under the Buddha’s wisdom-vision, it is entirely transparent and clear. The 《大宝积经》 (Mahāratnakūṭa Sūtra) emphasizes that the Buddha, as the “Great Guide” (大導師, mahānāyaka), is able to achieve “definitive knowledge” (決定知) with regard to all three types of beings—those of the good-definite group, the evil-definite group, and the indeterminate group. Even when beings of the indeterminate group are in the “non-appropriate places” (非處, asthāna) where causes and effects are intricately entangled, and may at any moment turn toward different destinies because of the rising and falling of karma, the Buddha knows their trajectories without omission and without error. This shows that the wavering and indeterminacy of sentient beings’ own minds does not obstruct an awakened one’s clear illumination of the laws of cause and effect.
3. Easily Falling into the Bad Destinies, and Compassionate Rescue Within Them
Because they lack a firm line of defense of right view (正見, samyag-dṛṣṭi), beings of the indeterminate group, in the long flow of birth-and-death, are extremely easily pulled by evil conditions and “堕于诸恶道” (fall into the various bad destinies). However, the 《大宝积经》 reveals an extremely warm and profound doctrine: the Buddha’s rescue does not take as its precondition whether beings have “met the standard.” For beings of the indeterminate group who have sunk into the bad destinies because their nature was not yet determined, the Buddha, even within the bad destinies, “亦为说涅槃” (also teaches nirvāṇa, 涅槃, for them). The faint light of the Buddha’s compassionate vows can penetrate the darkness of the bad destinies, and for beings who have fallen because of their indeterminate state, plant anew the seed of awakening.
4. Its Position in the Causal Network of Liberation and the Pure Land: The Necessary “Conversion of Group”
In the causal network of the Pure Land (淨土, jìngtǔ) and ultimate liberation, 不定聚 is given a rigorous position. As the dialogue between Ānanda and the Buddha in the 《大宝积经》 states, all sentient beings born in that Buddha-land’s Pure Land are able to ultimately attain unsurpassed bodhi (無上菩提, anuttara-samyak-saṃbodhi); and the reason why that land has no beings of the evil-definite or indeterminate groups is that beings in the states of the evil-definite and indeterminate groups “不能了知建立彼因” (are unable to understand and establish the cause for that [birth]).
In other words, “不定聚” itself does not automatically lead to liberation. People in an indeterminate state, because their minds waver and their causes and effects are unclear, cannot establish in the present moment the “definitive cause” that leads to the Pure Land or liberation. Therefore, throughout the entire path of practice, “不定聚” is the starting line for the vast majority of ordinary people’s cultivation; but the central task of cultivation is precisely—through hearing the true Dharma, accumulating provisions (資糧, sambhāra), and establishing vows (誓願, praṇidhāna)—to transform oneself from “wavering and indeterminate” into “正性決定” (definitive orientation toward the good).
A Walkthrough in Everyday Life
We often think of ourselves as “modern people” with principles, opinions, and rational independence. But if we use the rigorous classical definition of 不定聚 to conduct a “walkthrough” of contemporary life, we will find that we perfectly match the characteristics of the indeterminate group the vast majority of the time.
Scenario One: Morning Phone-Scrolling and Algorithmic Conditioning
* The scene: Waking up in the morning, you originally planned to recite sutras, meditate, or read. But your hand unconsciously reaches for your phone, opening social media or short videos. The algorithm, based on your latent desires, pushes a controversial news item; your emotions are instantly stirred; anger, anxiety, or curiosity takes over your brain, and before you know it, half an hour has passed. * Concept mapping: This is a textbook case of “drifting with conditions” (隨緣流轉). The mind has no fixed axis; whatever conditions the environment (the phone and the algorithm) offers, the mind shifts in that direction. * Common mapping error: Many people think, “I’m just casually looking; I can close it anytime,” mistakenly believing they possess control (正定, correct determination). But the classical definition of 不定聚 is precisely this kind of state—thinking one can control oneself, while in reality being extremely easily led by external conditions.
Scenario Two: Workplace Competition and Overtime Involution
* The scene: In daily life, you consider yourself a gentle, kind person. Yet when facing promotion competition, performance pressure, or covert exclusion by colleagues, in order to protect yourself or outdo others, you begin to say things against your conscience, play petty tricks, or even participate in slandering others. Afterwards you feel regret, but in that moment you were entirely swept along by the adverse conditions of the environment. * Concept mapping: This is the classic warning: dwelling in the indeterminate group, one is easily pulled by adverse conditions. Good roots are not yet firm; once encountering high-pressure or interest-conflict adverse conditions, the original “faint goodwill” collapses in an instant, and there is danger at any moment of “falling into the bad destinies” (墮於惡道)—creating evil karma, the mind’s power sinking downward. * Common mapping error: People often explain this as “in the world, one cannot help oneself” (人在江湖，身不由己), considering it a mature survival principle. But in Buddhist doctrine, this “cannot help oneself” is precisely the typical manifestation of being in the “indeterminate” state, because definitive right view has not been established.
Scenario Three: Intimate Relationships and Parenting Anxiety
* The scene: Facing your partner or child, when you are in a good mood and circumstances are smooth, you can be loving and tolerant (turning toward the good); but once you are tired from work, or the other person does not meet your expectations, your irritability, control, and hatred burst forth (turning toward evil). You swing frequently between love and harm. * Concept mapping: This displays the characteristic of the indeterminate group’s “unsettled nature”—one has not committed irrevocable determined evil karma (邪定), but neither has one established unconditional compassion and right mindfulness (正定). The quality of one’s life depends entirely on momentary emotions and external stimuli.
Why Contemporary People Need It
Contemporary life is extremely complex and fast-paced. This environment amplifies the fragility of 不定聚 to the utmost. There are three crucial reasons why contemporary people should understand and recognize 不定聚:
1. Breaking the Illusory Fantasy of “Self-Control”
Modern technology (recommendation algorithms, the attention economy, dopamine design) is essentially an enormously vast “system of external conditions.” Without the power of correct determination, modern people are like a small boat on huge waves. The algorithm knows your soft spots; public opinion knows your anxieties. Understanding 不定聚 allows us to clearly realize: before we have established firm right view, what we call “free will” is, most of the time, merely a stress response imposed by environment and desire.
2. Beware the Moral Complacency of “The Frog in Warming Water”
Many people think: “I haven’t committed any crime, nor any great evil that violates heaven and reason (not 邪定聚), so I must be a good person.” But the doctrine of 不定聚 reminds us: “not evil” is not the same as “correctly determined.” Not having committed great evil is only because your current environment has not yet pressured you to that point, or because you have not yet encountered a sufficiently large temptation of gain. If one does not actively establish a positive definitiveness, a life in the “indeterminate” state has a far higher probability of falling than rising in the long flow of saṃsāra.
3. Stimulating the Urgency of “Establishing the Definitive Cause”
The scriptures clearly state that being in the indeterminate group means one “cannot understand and establish the cause for that [birth]” (不能了知建立彼因), and therefore cannot respond to the Pure Land or achieve ultimate liberation. The lesson for contemporary practitioners is: practice cannot be entrusted to “letting things take their natural course.” If it is merely a 佛系 (fóxì, “Buddhist-lite”), go-with-the-flow, check-in style of casual cultivation, the undertone of one’s life remains 不定聚. We need to consciously, through hearing and contemplating the true Dharma, observing precepts, and making vows, forge the wavering mind into an unshakable 正定聚 (samyaktva-niyata-rāśi, the group definitely destined for the good), actively establishing for life an irreversible line of defense.
Common Misreadings and Clarifications
Misreading One: Thinking That “Indeterminate” Means “Buddhist-Lite, Going with the Flow, Open-Minded”—a Transcendent State Worth Pursuing
* Clarification: This is the most common literal misunderstanding of the term among contemporary people. In the modern context, “going with the flow” (隨緣) is often equated with “non-attachment, openness, and tolerance.” However, in classical Buddhism, 不定聚 is by no means a term of praise, but rather a dangerous, fragile state. Its “going with the flow” is a passive drifting—“falling with adverse conditions, rising with good conditions.” On the path of liberation, “不定聚” is a stage one is admonished to cross and transform as quickly as possible, not a reason to remain stagnant.
Misreading Two: Thinking That Because One Usually Accumulates Merit, Does Good Deeds, and Has Correct Worldview and Values, One Already Belongs to the 正定聚
* Clarification: In the rigorous definitions of the scriptures and treatises, the threshold for 正定聚 is very high. In the Hīnayāna abhidharma (阿毗達磨), one ordinarily must realize the path of seeing (見道位, darśana-mārga, at or above the first fruit, 初果) and cut off the delusions of views (見惑, darśana-heya) to be counted as entering the group definitely destined for the good; in the Mahāyāna common teaching (通教, tōngjiào) or the Pure Land approach, one must also establish firm, irreversible right faith and vows. The good deeds done by ordinary people on the basis of worldly morality, though praiseworthy, may still waver and collapse when faced with extreme adversity, illness, or the threshold of life and death. Therefore, the vast majority of worldly “good people” are still in the 不定聚—one must not be blindly self-satisfied.
Misreading Three: Thinking That Once One Falls into “Indeterminacy” or Even Accidentally Falls into the Bad Destinies, One Has Been Abandoned by Buddhism
* Clarification: This is a misunderstanding of the Buddha’s compassionate vows. The 《大宝积经》 particularly emphasizes the Buddha’s “definitive knowledge” (決定悉知) and “teaching nirvāṇa within the bad destinies” (惡道說涅槃). The Buddha not only sees clearly the chaotic trajectories of indeterminate beings, but also does not abandon them because they fell due to wavering. Even if beings sink into the bad destinies because of their indeterminacy, the Buddha’s compassionate vows will still, within the bad destinies, proclaim for them the Dharma of nirvāṇa. This teaching tells us: although an indeterminate life is fragile, the gate of awakening is always open to it—there is absolutely no possibility of utter destruction or eternal abandonment.
