这个概念在说什么
The classical entry provided is unusually brief — a single line: "依根性或修證差別所分四類人" (four categories of persons divided according to differences in root faculty and cultivation/realization). That brevity is itself meaningful: 「四種人」不是某一部經裡唯一的清單，而是一個反覆出現的「分類框架」 — a meta-concept. Different sūtras and treatises propose different four-folds depending on the question they are trying to clarify. What unites them is a single pedagogical intent: to honor the fact that sentient beings differ in starting points, responsiveness, and vows — and that the Dharma must be taught in light of those differences, not flattened onto a single template.
The phrase 「依根性或修證差別」 tells us the framework cuts along two axes: - 根性 (root faculty) — the deeply-conditioned orientation one carries into practice (in Yogācāra called 種性 / *gotra*, "seed-nature") - 修證 (cultivation and realization) — where one actually stands on the path
Below I will lay out the four most widely-recognized four-fold schemes in Chinese Buddhist tradition. I will then develop the first one — 凡夫 / 聲聞 / 緣覺 / 菩薩 — as the spine for the rest of the essay, because it most directly fits "依根性或修證差別". I will pull in the second scheme — the four horses — for the life walk-through, because its concrete imagery makes the abstract come alive.
Scheme A — Four Vehicles (依修證方向)
This is the framework most readers of Chinese Buddhist literature will meet first. It appears across the Mahāyāna sūtras — most importantly in the 大涅槃經 (*Mahāparinirvāṇa Sūtra*), where it becomes the scaffolding for asking whether each type possesses 佛性 (*Buddha-nature*); in the 法華經 (*Lotus Sūtra*), whose 藥草喻品 (Parable of the Medicinal Herbs) says the rain of dharma falls equally but the soil differs; and in the 維摩詰經 (*Vimalakīrti Sūtra*), where the four are shown to be porous categories rather than sealed boxes.
The four are:
1. 凡夫 (*pṛthagjana* / ordinary being) — those whose root faculties are not yet decisively oriented toward liberation. They remain caught in saṃsāric habits; 出離心 (the mind of renunciation) is either absent or only weakly formed.
2. 聲聞 (*śrāvaka* / "hearer") — those who, having heard the Buddha's teaching, enter the path with the goal of personal liberation from the round of birth and death. Their definitive realization is 阿羅漢 (*arhatship*).
3. 緣覺 (*pratyekabuddha* / "solitary realizer") — those who awaken primarily through direct observation of 因緣 (causes and conditions), typically by contemplating the 十二因緣 (twelvefold chain of dependent origination), often in eras when no Buddha appears in the world. Their realization is 辟支佛 (pratyekabuddha fruit).
4. 菩薩 (*bodhisattva*) — those who, having generated 菩提心 (the mind of awakening), undertake the long path for all beings, vowing to attain complete Buddhahood before entering final nirvāṇa.
The differences cut across three dimensions: - 根性 — the kind of seed-nature one carries - 修證 — the practices one undertakes and the fruits one attains - 心量 — whether the orientation is inward (聲聞, 緣覺) or outward to all beings (菩薩)
Scheme B — Black-and-White Four-Fold (依身口意清淨度)
In the early Buddhist āgama literature — particularly the 增壹阿含經 (*Ekottara-āgama*) and the corresponding Pali *Aṅguttara Nikāya* — there is a vivid four-fold classification based on the relative purity of body, speech, and mind:
- 黑中之黑 (darkest of dark): body, speech, and mind all unskillful - 黑中之白 (white within dark): body and speech unskillful, but mind skillful - 白中之黑 (dark within white): body and speech skillful, but mind unskillful - 白中之白 (whitest of white): body, speech, and mind all skillful
Usually framed as a karmic teaching, it is also used to classify persons by their dominant orientation — and to point out that the mind/intention layer is decisive even when outward conduct looks respectable.
Scheme C — The Four Horses (依對法的回應模式)
In the 雜阿含經 (*Saṃyuktāgama*) and the corresponding *Saṃyutta Nikāya*, the Buddha tells the parable of 四種馬 (four kinds of horses). In the commentarial tradition — and in much popular Chinese Buddhist pedagogy — it is directly applied to four types of learners, by the way each horse responds to the rider's signals:
- 良馬 (good horse) — responds at the slightest turn of the rein. Those who awaken deeply with minimal prompting. - 鈍馬 (dull horse) — responds only when the whip falls. Those who need steady, repeated teaching and accountability. - 惡馬 (bad horse) — responds only when wounded or in pain. Those who awaken through crisis, suffering, or hitting bottom. - 駑馬 (very poor horse) — does not respond even when wounded. Those whose current obscurations are so thick that this-life awakening does not take hold.
A note on honesty: the sūtra itself is a parable about horses; the extension to "four types of persons" is a pedagogical application developed in the commentarial tradition. I include it here because, in Chinese Buddhist education, it is by far the most-used scheme when a teacher asks "which kind of practitioner are you, really?"
Scheme D — Yogācāra Gotras (often presented as four)
The 瑜伽師地論 (*Yogācārabhūmi-śāstra*) classically distinguishes 五種性 (five *gotras*): 聲聞種性, 緣覺種性, 菩薩種性, 不定種性 (undetermined), and 無種性 (no-seed-nature / *icchantika*). Some traditions, for working purposes, drop the contested 無種性 and present four gotras as a scheme. The full five-gotra debate is its own large topic, treated separately in the Yogācāra literature.
For the rest of this essay I will work primarily with Scheme A and selectively with Scheme C, because together they offer the richest material for mapping onto contemporary life — Scheme A for the where am I question, Scheme C for the how do I respond question.
生活里的走查
Scene 1 — A week that didn't go as planned
Reading it through Scheme C, the four horses' responsiveness to the teaching of life:
Suppose on Monday your boss gives you a piece of feedback. By Friday, four colleagues have responded in four different ways.
The 良馬 colleague heard the feedback once, paused, and quietly restructured their week. By Wednesday the change was visible. They didn't need a follow-up meeting; they didn't need a written action plan. The teaching landed on the first signal.
The 鈍馬 colleague wanted to do better but kept falling back into old patterns. They asked for a follow-up meeting. They wrote a checklist. They signed up for an accountability partner. They need the whip of structure to keep moving — not because they don't care, but because their conditioned patterns need more friction to shift.
The 惡馬 colleague didn't really move all week. Then on Friday evening, something painful happened — a missed deadline, a friend saying "you keep doing this" — and at the moment of being wounded, something cracked open. By Sunday night, this person has rethought their entire approach. They are not worse than the 良馬; they simply awaken through impact rather than through a gentle signal.
The 駑馬 colleague also got the feedback, and also got the painful Friday evening event. By Monday of the next week, they have constructed an external explanation for everything — the boss was unfair, the deadline was unrealistic, the friend was projecting. The teaching hasn't landed yet. Not because they are bad, but because the patterns are currently thick enough to deflect almost anything.
A crucial mapping note: it is tempting to read this as a ranking. It is not. The 良馬 in this life may be the one whose sharper conditions are exactly what made the path available now; the 駑馬 may be the one who, after many more cycles, finally arrives with great force. The scheme describes this-life responsiveness, not ultimate worth. Hold this in mind as we move on — it is the most common place contemporary readers get it wrong.
Scene 2 — A quiet Sunday, asking 「這一切到底是為了什麼?」
Reading it through Scheme A — 凡夫 / 聲聞 / 緣覺 / 菩薩:
The morning is open. No meetings, no children to ferry, no inbox. For the first time in weeks, there is silence. Now look at what each "type" does with that silence.
In 凡夫 mode, the question may not even arise. The hands reach for the phone. Half-watching a show, ordering food, drifting toward sleep. There is no moral failure here — it is the texture of a mind whose root faculty has not yet been decisively oriented toward asking. The 大涅槃經, when it talks about 凡夫, does not condemn this state; it simply describes it as the default human condition — and, importantly, as the condition from which awakening becomes possible at all.
In 聲聞 mode, the silence becomes uncomfortable. Something surfaces: *"I keep doing the same things, but nothing feels like it's going anywhere."* The orientation is "I need to find my own way out of this." Someone in this mode might sign up for a meditation class, begin therapy, start reading something with depth, or begin a daily practice. The direction is inward — toward self-liberation — and this is treated with full respect in the Buddhist tradition. The 聲聞 path is not a lesser path; it is a complete path. The Buddha's own community was predominantly śrāvakas.
In 緣覺 mode, the silence produces something different: not a search for a teacher, but a direct observation of cause and effect. Watching a child grow. Seeing a friend go through a difficult divorce. Sitting by a window. And something clicks: *"Oh — everything is impermanent; my clinging is the actual source of the suffering."* This kind of insight can arrive spontaneously, often to people who are not very religious or institutional at all. The 緣覺 path is, in a sense, the most self-generating of the four — it requires little external scaffolding, only a mind honest enough to look.
In 菩薩 mode, alongside the personal unease, a second question arises: *"If I see this clearly, others must be in this same fog — what can I do?"* This is not "more spiritual" in some metaphysical sense; it is a deliberate widening of the scope of concern. Someone in this mode might be drawn to teaching, nursing, counseling, social work, parenting taken seriously, or activism. Their danger is over-effort and burnout — which is why the tradition insists that 菩薩 *work* must be grounded in 菩薩 *practice*, not the other way around.
Mapping mistake 1 (the most common): people often imagine 菩薩 is the "highest" type and try to skip straight there. The classical teaching is the opposite: 菩薩 practice presupposes a foundation in self-cultivation. You cannot authentically serve others from a chaotic mind. A bodhisattva who has not done their own inner work tends to become a savior, then a burnout, then a cynic.
Mapping mistake 2: people also assume these are fixed identities. The Mahāyāna texts are very clear: 種性 is not destiny. Root faculties can ripen, fade, or shift across lifetimes — and within one life, a person may pass through several of these modes, sometimes in a single afternoon. The labels describe the *current* texture of the mind, not its permanent address.
Scene 3 — How a teacher, parent, or therapist uses the framework
This is where the four-fold becomes a pedagogical instrument rather than a self-classification tool.
- For a 凡夫-mode student: don't dump deep dharma on them; first help them settle. Build a regular rhythm. Maybe just teach kindness toward themselves and let the questions germinate on their own schedule. - For a 聲聞-mode student: they are hungry; give them concrete practices — a meditation form, a structured path, a clear sequence. Let them have their own process. Don't compete with them. - For a 緣覺-mode student: don't over-institutionalize them. Their insight comes in flashes. Provide conditions for stillness, but don't force a curriculum on them; you'll just kill the insight. - For a 菩薩-mode student: their danger is over-effort. Your task as their guide is to slow them down, anchor them in their own practice, and warn against savior complexes and martyrdom dressed up as service.
This is essentially what the 法華經·藥草喻品 means when it says the rain of dharma falls equally — the teaching is one — but the soil differs. The four-fold protects you from the delusion that the teaching "didn't take", when in fact the soil just absorbed it differently than you expected.
当代人为什么需要它
1. 它阻止一种常见的自我挫败：「我应该已经觉醒了」
Modern spiritual culture, especially online, is saturated with images of awakened teachers, "high-vibration" lives, and people who seem to have figured everything out by thirty. Anyone who is just beginning to question their life feels they are doing it wrong. The 四種人 framework reframes this entirely: there is no wrong place to start. 凡夫 is not a failure mode; it is the human starting point. Even the Buddha, in previous lives, was a 凡夫 for countless cycles before his awakening. The framework gives permission to be where you are, without comparison.
2. 它讓教學者真正「對機」
Whether you are a parent, a manager, a therapist, a teacher, or a friend giving life advice, the four-fold reminds you that one size fits none. Someone in 惡馬 mode (Scheme C) doesn't need another gentle reminder — they may need a real reckoning. Someone in 良馬 mode doesn't need a five-hour lecture; they need one clear sentence. Knowing which type you're dealing with saves both sides enormous wasted effort and a lot of unnecessary guilt.
3. 它保存了道路的多樣性
Contemporary culture pushes toward a single metric of success — wealth, status, productivity, or, in some circles, "spiritual attainment." The 四種人 framework insists that realization is multi-dimensional. 聲聞 realizes self-liberation. 緣覺 realizes via direct insight. 菩薩 realizes through vow and service. None of these is more "real" than the others. This is a powerful counter-narrative to the monoculture of "you should be / want / achieve X."
4. 它保護修行人不被「種性」所困
Used properly, the framework prevents two opposite errors: - Fatalism — "I'm a 凡夫, so nothing will change." Wrong: 種性 ripens through conditions; even the 法華經 describes the 鈍根弟子 (dull-rooted disciple) eventually arriving at full realization through patient conditions. - Pride — "I'm a 菩薩 type, so I'm more advanced." Wrong: the bodhisattva path is precisely a path of relentless self-emptying, not self-aggrandizement.
In both directions, the framework disarms the ego's tendency to weaponize every teaching, including this one.
常见误读与澄清
Misreading 1 — 把四種人當成高低階梯
Many readers see 凡夫 → 聲聞 → 緣覺 → 菩薩 as a hierarchy with 菩薩 at the "top." This is the single most common mistake. In the Mahāyāna framing, 菩薩 is not "higher" in the sense of being more spiritually superior; it is a different orientation of vow. A 聲聞 who has fully realized nirvāṇa has, in one important sense, arrived at the end of their path; a 菩薩 has chosen to delay arrival in order to work for others. Neither is "better."
Even the early Buddhist texts explicitly criticize ranking these as class grades. The framework is functional (what kind of path does this person walk?), not evaluative. The 法華經's famous reorientation — 會三歸一, that the three vehicles ultimately converge into the one vehicle — is precisely a teaching against the ladder reading.
Misreading 2 — 種性是命定
A second widespread error is reading 種性 as fixed destiny: "I have a 聲聞種性 so I can never become a Buddha." This contradicts both the 大涅槃經's teaching that all beings possess 佛性, and the 瑜伽師地論's own analysis showing that 不定種性 (undetermined) covers most beings — meaning one's path is not locked in.
In contemporary terms: think of "root faculty" not as DNA but as deeply-conditioned patterns. Patterns can transform; they are not fate. A person who has spent thirty years in 鈍馬 mode can, through a single transformative relationship or crisis, shift into a different responsiveness pattern. The framework describes tendencies, not destiny.
Misreading 3 — 把四種馬讀成「靈性資質評分」
When the four-horses parable is reduced to a personality quiz ("which horse are you today?"), it loses its force. The point is not to label yourself; it is to notice, with compassion, where you are right now, and to recognize that the Dharma is available in all four conditions. The 駑馬 is not condemned; they are simply someone whose current conditions for awakening are minimal — which is itself a teaching about impermanence and the preciousness of this life. A teaching that lets you look at the 駑馬 in yourself or in others without flinching, without contempt, and without despair — that is a teaching doing its job.
Misreading 4 — 隨信行 / 隨法行 ≠ 四種人
In Yogācāra texts there is a famous two-fold classification of practitioners: 隨信行 (one who walks by following faith) and 隨法行 (one who walks by following direct understanding of dharma). Some popular presentations stretch this into a four-fold (by adding combinations) and conflate it with 四種人. They are different teachings; the 隨信/隨法 distinction should be treated on its own terms, because it answers a different question — *how does this practitioner learn best*, rather than *what path are they on*.
A closing thought
The deepest service the 四種人 framework offers is not classification itself, but the gentle dismantling of comparison. Once you really see that the four are not a ladder but a fourfold mirror — 凡夫-mode asking the question, 聲聞-mode turning inward, 緣覺-mode seeing directly, 菩薩-mode turning outward — then your own position stops being a failure, and other people's positions stop being a threat. The teaching lands where it lands, in the soil it lands in. The Dharma is not diminished by the slowness of the soil; the soil is not diminished by the speed of the rain. This is the kind of seeing that, regardless of which "type" you happen to be this week, makes the whole conversation worth having.
