In the *Mahāvairocana Sūtra Commentary* (《大毘盧遮那成佛經疏》, T1796), the eighteenth of the "sixty minds" (六十心) is given a four-character gloss that is both precise and counter-intuitive: 「云何人心，謂思念利他。」 — "What is the human mind? It is the mind that contemplates the benefit of others." To a modern reader this looks almost noble. The classical text, however, goes on to specify that this "benefit of others" includes two seemingly opposite activities: planning how to give great benefit to those who have helped us, and planning how to repay those who have not treated us well. So "人心" is not "the kind mind," not "compassion," not even "altruism." It is a specific *shape* the mind takes when its subtle attention is constantly running calculations about human beings.
To understand what 人心 really is — and why a Tang-dynasty esoteric commentary would single it out as one of sixty varieties of ordinary mind — we need to hold both halves of the definition together, and we need to see where it sits inside the larger framework of *the sixty minds* itself.
What This Concept Says — and Where It Sits in the Whole Map
The framework: 六十心 and 百六十心
The 大日經疏 does not give us a single label like "ordinary mind" or "deluded mind." Instead, it offers what you might call a *taxonomy of mind-shapes* — sixty distinguishable patterns by which an ordinary being's awareness gets caught up, each with its own object, habit, obstruction, and remedy. These are not sins. They are describable *fingerprints* of mentation (念慮), and the practice is to learn to recognize them so they can be dismantled.
The framework runs as follows. After the sixty specific "minds," the text adds a closing one — the 「猨猴心」 (note the classical character 猨, not 猿), "ape-mind," the mind so scattered it lets go of one thing only to grab the next ("放一捉一"), treated by *not following the drift* and *tying attention to one anchor*. Then the text expands the list into the 百六十心 (one hundred and sixteen minds), arriving at that count by enumerating greed, hatred, delusion, pride, and doubt (貪、嗔、癡、慢、疑) multiple times — five root afflictions, each multiplying into subsidiary patterns. The whole discussion is offered as the commentary's answer to the phrase 「諸心想及心殊異」 ("the various minds, and their differences"), i.e. *why minds behave so differently in different people and at different times.*
Two things follow from this. First, 人心 is one of sixty, not the whole of ordinary mind. Second, the framework's goal is not to suppress thought but to bring one into alignment with 淨菩提心 (pure bodhicitta) — the unconditioned awakening-mind. The teacher (阿闍梨, ācārya), in this tradition, is to 「將這些心相一一簡去」 — strip these mind-shapes, one by one, from the disciple's inner ground.
The classical definition, in full
The eighteenth entry is exactly four characters in its compact form, 「謂思念利他」 ("it means contemplating/planning the benefit of others"), but the surrounding commentary explains that this "benefit of others" is in fact the whole range of *interpersonal calculation*:
對有恩者設法使其得大利 — *For those who have helped us, devising means to give them great benefit.* 對曾不饒益者則思量報復 — *For those who once treated us ill, calculating how to repay them.* 皆屬此心所攝 — *All of this falls under this mind.*
And further, the mind of 人心 runs constantly on 「理人利物之計」 — *calculations for managing people and benefiting things,* i.e., schemes, strategies, arrangements, bookkeeping — all centered on other humans as the object.
The pointed observation embedded here is this: the surface content of the thought does not determine its classification. Whether the calculation produces a generous gift or a quiet payback, whether the goal looks saintly or shady, *the mind-shape is the same*. It is the mind turned outward into the field of persons and their affairs.
What the remedy is — and isn't
The classical antidote (對治) given is 「自觀心行，早求法利」 — *Self-observe the mind and conduct; seek the dharma-benefit early.* And the explanation: 「不應讓心識紛紜馳逐於他緣」 — *The mind should not be allowed to rove and chase among external things.*
Note carefully what is *not* being said. The text is not saying: *don't help others*. It is not saying: *your motives must be pure before you act.* It is not even saying: *being kind is wrong.* It is diagnosing a directionality of subtle attention — the continuous, low-grade running of calculations about other people — and pointing out that this constant outward running is precisely what obstructs a practitioner from turning the gaze inward to one's own conduct and from making the dharma the priority. The remedy is *where the inner eye rests*, not what the visible behavior looks like.
This is also why the framework's destination is not silence but 淨菩提心. The practice is not to extinguish mentation; it is to redirect it away from the labyrinth of human accounts and toward a qualitatively different orientation.
The neighboring minds, so we don't confuse 人心 with them
To keep 人心's meaning from blurring, it helps to see what sits beside it on the list (all from the 大日經疏):
- 諍心 — the mind fixed on agreement and disagreement, gain and loss. - 無諍心 — the mind holding no "for" or "against," willing to take in reasonable speech and drop "right/wrong." - 天心 — the mind wishing that whatever one reflects upon succeed at will. - 阿修羅心 — the mind deeply delighting in the rewards of saṃsāra. - 龍心 — the mind thinking of vast wealth and being greedily never-satisfied. - 女心, 自在心, 商人心, 農夫心, 河心 — various desire-, planning-, and dual-leaning patterns named after social roles.
So 人心 is specifically the mind whose *所緣* (object) is other persons and the ledgers of gift and grievance that bind us to them. 諍心 fights inside that field; 天心 wishes inside it; 龍心 hoards inside it. 人心 is the basic structural form, in which the mind treats "people and what to do about them" as its constant preoccupation.
An Examination in Daily Life
To walk this through with a concrete contemporary case, take a fairly ordinary stretch of an adult week.
A colleague, Mei, helped you land a promotion eight months ago by quietly flagging your work to the right person at the right moment. The promotion is now well behind you, but the mind of 人心 is still running its calculation. On a slow Sunday you catch yourself doing mental arithmetic: *how would Mei most like to be repaid, what would be weighty enough not to look cheap, what gesture would actually land as meaningful to her rather than to me?* Then you run a second loop: *how will Mei receive it, will she think it's over-the-top, will it look like I'm paying a debt rather than being a real friend?* Before you have done a single visible thing, the mind has spent a long quiet afternoon running interlocking calculations about one other person.
Now look at a second track. A former collaborator, Daniel, took credit for a project in which you did most of the work, and you have not forgotten. The text says explicitly that 人心 *also* includes 「對曾不饒益者則思量報復」. So the same week, when Daniel's name appears in a thread where his team is struggling to ship something, you notice a small inner process flicker on: *I wonder how this is going for them; what would it feel like if it failed publicly; it's their own doing.* You have not said anything. You have not acted. But the mind is already composing the choreography of one possible future in which Daniel is repaid without your fingerprints anywhere near it.
These two tracks look different — one warm, the other cold — and yet they are the same mind-shape. The common feature is not their moral color. The common feature is that the mind is ceaselessly calculating about other human beings as its primary occupation. Mei is a person-as-object. Daniel is a person-as-object. The calculator is the same.
Now: what would the classical remedy of 「自觀心行，早求法利」 look like here?
It does not ask you to be rude to Mei, nor to send Daniel an apology. What it asks is something prior and more interior: notice that your mind is in 人心. Notice how much of your mental bandwidth is spent on the books of others. Notice that the projector of your attention is pointed outward, into a long accounting ledger of human favors and slights, and only secondarily, if at all, onto your own mind and its actual condition. The remedy is to gently withdraw the projection — not to change the cast of characters on the screen — and ask: *what is the mind, apart from all these accounts? what does it actually look like when not running this calculation? and what is the dharma-borrowing (法利) I am here for that I keep postponing because the ledgers are so loud?*
The places contemporary people most often map this concept wrongly are:
1. Reading 人心 as "kind hearted" because it literally contains 利他 ("benefit others"). The classical point is that the "kind gesture" and the "quiet revenge scheme" are *the same mind-shape*, and neither is what 淨菩提心 has in view. 2. Reading self/other as the relevant axis. Modern readers want to ask, "is this selfish or selfless?" The text is not on that axis at all. The axis is *outward-spinning vs. inward-returning*. A selfless-seeming person who runs twelve mental simulations about other people's lives is still in 人心; a self-interested person whose mental activity has actually withdrawn from the human-accounting game is in a different relation to the framework. 3. Reading the remedy as "stop helping people." 自觀心行 is not a license for interpersonal coldness. It is a practice of retrieving attention. The practice produces a kind of uncluttered availability to others that is qualitatively different from the busy, calculating kindness it replaces — but it never begins by addressing behavior. It begins by changing where the *subtle mind* is pointed.
Why Contemporary People Need This
Modern conditions pour fuel directly onto the 人心 pattern. A few brief observations, with the customary caveat that these are comparisons, not proofs, and that one should not mistake the analogy for the teaching itself.
First, contemporary life is densely *interpersonal.* Our work is project-based and reputation-mediated; our evenings cycle through close family, in-laws, an ex's extended network, and a wider community with which we co-manage children, parents, and shared resources. We are not surrounded by fewer people than our ancestors were; we are surrounded by *more concurrent relationships* with thinner stability, and the mind accordingly has more ledgers to keep open at once. This is structurally favorable to 人心, and unfavorable to whatever a quieter, inward-oriented practice might produce.
Second, social platforms specifically amplify the texture that 人心 relies on. The visibility of others' fortunes and slights is now instantaneous. The mind is gently, constantly cued to compare, to recalculate standing, to wonder what a delayed reply means, to notice who liked what. Neuroscience has documented something adjacent — that social-media feedback activates parts of the reward system with profiles not unlike variable-ratio reinforcement — but this is at most an interesting parallel; it does not prove any Buddhist claim, and the science itself is still debated and oversimplified in popular summaries. The classical diagnosis stands without needing the science.
Third, most people who are tired in a particular modern way — the kind where one cannot precisely say why, where leisure does not restore — are tired *this way.* They are tired of their own mind's endless quiet arithmetic about other people. Recognizing 人心 does not require entering a monastery; it offers a non-evangelical relief for a condition that ordinary introspection has not been able to name.
Fourth, the remedy the text gives is, in practice, gentle and legible: 自觀心行，早求法利. In contemporary language: bring attention back to one's own mind and conduct, and put the dharma-borrowing (the actual teaching one is here for) ahead of the administrative task of running other people's affairs. That is not a forbidding program. It is a specific redirection of attention that, patiently applied, begins to cool a very recognizable kind of suffering.
Common Misreadings and Clarifications
"人心" is not "human nature." In colloquial Chinese, 人心 can mean roughly "the human heart," "what people are like," or "public sentiment." The classical term is narrower and more technical: it is one of sixty named mind-shapes in the esoteric commentary's diagnostic map. Importing the colloquial range will dilute the entry almost beyond recognition.
"人心" is not "selfish mind," nor is its opposite "selfless compassion." The classic axis is different. A person with no human-accounting agenda at all — neither gratitude-rolls nor revenge-rolls — is, from this framework, *not* in 人心, regardless of whether their acts look selfish or selfless on the surface. And a person full of warm altruistic visions of how to repay or uplift others is still in 人心, because the projector of attention is still pointed outward.
"人心" overlaps with 諍心 but is not the same. 諍心 is the mind of *contention* — gripped by "agreement vs. opposition, gain vs. loss." 人心 is broader: it includes warm and generous schemes, even ones that never argue with anyone, so long as other persons are the constant preoccupying object.
The remedy is not "don't be nice to people." 自觀心行 ("self-observe the mind and conduct") is an attention-practice. It changes the *subtle* condition from which visible behavior arises. Practitioners who have understood this correctly emerge with less anxiety-driven busyness in their relationships, not more coldness.
人心 is only one of sixty. This means that recognizing 人心 and redirecting out of it is *not the end of the practice.* After 人心, the list goes on to 天心, 阿修羅心, 龍心, 猨猴心, the roots 貪嗔癡慢疑, and their expansions — until the practitioner arrives at the framework's stated destination, 淨菩提心, the unconditioned awakening-mind for which all the dismantling is preparation.
The classical text is not asking contemporary people to become more aloof. It is asking them to recognize, with some precision, one of the most pervasive patterns in their inner life — *the mind that thinks and schemes on behalf of other persons, almost without stopping* — and to notice that this pattern, however socially useful it appears on the surface, quietly crowds out something much more important: the simple, inward work of seeing one's own mind and cultivating what one is really here for.
