What this concept is saying
*Fei xin fei Fo* (非心非佛, “neither mind nor Buddha”) is a Chan expression for dismantling attachment to both “mind” and “Buddha.” It is not a metaphysical declaration that mind and Buddha do not exist, nor a final doctrine offered in place of “mind is Buddha.” It is medicine prescribed in response to a particular fixation—and medicine is successful when it cures the illness, not when the patient begins worshipping the bottle.
The expression is associated especially with Mazu Daoyi’s teaching tradition. Its meaning becomes clear only when read beside *ji xin ji Fo* (即心即佛, “this very mind is Buddha” or “mind itself is Buddha”). The *Records of the Ancient Worthies* (*Guzunsu yulu*, 《古尊宿語錄》) preserves the celebrated exchange:
“Why does the master say, ‘Mind itself is Buddha’?” The master said, “To stop a child from crying.” “What about when the crying has stopped?” “Neither mind nor Buddha.”
The image gives us the whole pedagogical structure. A child is crying because it thinks what it needs is somewhere else. Similarly, a practitioner may imagine awakening as an exalted object possessed by a remote Buddha, attainable only after becoming someone fundamentally different. “Mind itself is Buddha” interrupts that outward search: do not abandon immediate experience in pursuit of a sacred object elsewhere.
But the sentence that ends one search can begin another. The practitioner may now seize “mind” as a hidden spiritual substance: a pure inner witness, an eternal consciousness, a special state behind ordinary experience, or an essence called “Buddha-mind.” At that point, “mind itself is Buddha” has become another possession. “Neither mind nor Buddha” removes the new attachment.
This is why the *Records of the Ancient Worthies* calls the saying “examining the illness and prescribing the remedy” (驗病施方). Its truth is inseparable from its function. It does not construct a second philosophy in which an entity called “non-mind” replaces an entity called “mind.” It stops the practitioner from converting provisional language into an absolute.
The two expressions therefore work as a paired movement:
1. “Mind itself is Buddha” cuts through alienation—the belief that awakening must be sought outside the life presently being lived. 2. “Neither mind nor Buddha” cuts through appropriation—the attempt to identify, possess, define, or preserve some inner thing as “my awakened mind.” 3. “Not mind, not Buddha, not a thing” (不是心不是佛不是物), the third formulation listed in Dahui Zonggao’s *Recorded Sayings* (*Dahui Pujue chanshi yulu*, 《大慧普覺禪師語錄》), removes the temptation to turn the negation itself into a subtle object or ultimate principle.
These are not three competing theories. They are three interventions. Dahui warns that if one remains occupied with deciding which statement is “correct,” one is being used by the three sayings. Freedom means being able to use the sayings without being used by them.
That point is dramatized in the encounter between Mazu and Damei Fachang. Damei awakened through Mazu’s “mind itself is Buddha” and later heard that Mazu was now teaching “neither mind nor Buddha.” He replied:
“Let him have his ‘neither mind nor Buddha’; for me, it is simply ‘mind itself is Buddha.’”
When Mazu heard this, he said that “the plum is ripe”—a play on Damei’s name. Damei’s maturity did not consist in choosing the older slogan over the newer one. He was no longer pushed about by reports of changing formulations. Had he abandoned his realization merely because a new phrase sounded more advanced, he would still have been seeking certainty in words.
Dahui summarizes the matter with characteristic precision. Asked which was right—Damei’s “mind itself is Buddha” or Mazu’s “neither mind nor Buddha”—he answered:
“Both are right; both are not right.” —*Dahui Pujue chanshi yulu* (《大慧普覺禪師語錄》)
“Both are right” means that either can liberate when it meets the corresponding illness. “Both are not right” means that neither is an independently valid description to be grasped apart from circumstances. Chan language here is performative: it is meant to loosen a grip, not furnish the mind with a more sophisticated object to grip.
This also explains the relation between “neither mind nor Buddha” and *prajñā* emptiness. The *Diamond Sūtra* (*Vajracchedikā Prajñāpāramitā Sūtra*, 《金剛般若波羅蜜經》) employs the pattern “the Tathāgata says that a composite is not a composite; therefore it is called a composite” (如來說一合相，即非一合相，是名一合相). Dahui explicitly invokes this pattern when discussing the play of affirmation and negation. The point is not that language is useless. It is that a name does not establish an independent essence in what it names. One may use “mind,” “Buddha,” and “awakening,” provided one does not mistake useful designation for self-existing reality.
“Neither mind nor Buddha” therefore occupies a precise place on the path of liberation. It addresses attachment at the level of the Dharma itself. Ordinary craving grasps possessions, status, sensations, relationships, and identities. Spiritual craving can grasp purity, insight, Buddha-nature, meditation, emptiness, and even non-attachment. The latter objects sound nobler, but the structure of bondage is the same: “There is something I must obtain, define, secure, or become.” Chan applies the teaching of non-grasping to its own teachings.
Yet negation is not the destination. Yuanwu Keqin’s *Recorded Sayings* (*Yuanwu Foguo chanshi yulu*, 《圓悟佛果禪師語錄》) says:
“Neither mind nor Buddha—put it to one side. If you call it Buddha, you add a head on top of your head. If you call it Dharma, you bind yourself without a rope.”
“Put it to one side” is essential. The saying is a thorn used to remove a thorn. Keeping the second thorn in the wound is not liberation.
Yuanwu can consequently move from negation back into complete affirmation:
“It is not mind, it is not Buddha. The whole mind is Buddha; the whole Buddha is the human being; human and Buddha are not two.” —*Yuanwu Foguo chanshi yulu* (《圓悟佛果禪師語錄》)
This is not carelessness or contradiction. When “mind,” “Buddha,” and “human being” are no longer conceived as sealed substances confronting one another, ordinary life need not be rejected in favor of a sacred elsewhere. Negation prevents fixation; renewed affirmation prevents nihilism. What remains is not an inert blank but responsive living without the burden of manufacturing a spiritual essence.
A walkthrough in everyday life
Imagine an exhausted commuter standing in a crowded train after a difficult day. She opens her phone and sees that a colleague has received the promotion she wanted. Several processes unfold almost instantly: bodily tension, disappointment, comparison, the thought “I am falling behind,” an impulse to scroll further, and a fantasy that a calmer, more successful version of herself would not feel this way.
First comes the ordinary outward search. She thinks relief lies in obtaining the right job, recognition, relationship, productivity system, meditation app, or ideal state of mind. Even spirituality can enter the same marketplace: “If I find the right teacher or technique, I will finally become peaceful.”
Here “mind itself is Buddha” functions as the first medicine. It does not mean that every passing thought is wise, that resentment is enlightenment, or that whatever she does is automatically Buddhist practice. It redirects the search. The discomfort, comparison, bodily contraction, and knowing of them are not obstacles standing outside the field of practice. This very event is where greed, aversion, identification, impermanence, and awareness can be seen. There is no need to manufacture a sacred experience before practice begins.
She puts down the phone and attends to what is happening. Tightness is tightness; heat in the face is heat; disappointment is disappointment; the sentence “I am a failure” is a thought appearing under conditions. None has to be denied, and none needs to be promoted into a permanent self.
Then a subtler mistake appears. She thinks: “Behind these reactions there must be a pure awareness. That true mind is the Buddha. If I can stay identified with it, nothing will disturb me.” This sounds spiritual, but it has reconstructed the same acquisitive pattern. The promotion was once the coveted object; now “pure awareness” is the coveted object. The imagined owner—“I”—has become more refined, not necessarily freer.
At this point, “neither mind nor Buddha” is the fitting medicine. Look directly: where is the independent entity called “mind”? Is it the bodily tension, the disappointed feeling, the mental image, the act of recognizing, the impulse to defend herself, or the awareness of all these? Each is conditioned and changing. No single episode, hidden observer, or sum of episodes needs to be enthroned as an immutable spiritual substance.
Likewise, where is the “Buddha” she is trying to acquire as a perfected identity? If Buddha becomes an ideal self-image—always composed, never jealous, invulnerable to criticism—it is functioning as another instrument of self-rejection. “Neither Buddha” cuts off that imagined trophy. It does not deny buddhahood; it denies her attempt to possess buddhahood as a thing that would certify “me.”
Then comes the most easily missed turn. She may conclude, “So nothing is real, there is no mind, ethical effort is pointless, and I should detach from everything.” That is not liberation but attachment to negation. “Not mind, not Buddha, not a thing” prevents her from turning “nothing” into a final thing. The train is still crowded. Envy still hurts. Her colleague is still a person rather than a projection in her private philosophy. Causes have consequences; speech can wound; conduct matters.
So she answers the colleague’s message without either pretending to be delighted or discharging her pain through sarcasm. Perhaps she waits until the agitation settles. Perhaps she congratulates the colleague sincerely while later discussing her own career prospects with her manager. Non-grasping does not erase discernment. It allows discernment to operate without being completely commandeered by the demand to protect an identity.
The walkthrough can be stated compactly:
- “The answer is somewhere outside me”: “Mind itself is Buddha” interrupts estrangement and outward spiritual seeking. - “Then my true mind must be an inner, pure object”: “Neither mind nor Buddha” dismantles that reification. - “Therefore nothing exists and nothing matters”: the third saying blocks nihilistic reification of negation. - “Which sentence is finally correct?”: Dahui’s ‘both right and both not right’ exposes the demand for a context-free formula. - “How, then, should I live?”: meet conditions clearly, act responsibly, and do not convert experience or doctrine into a self to defend.
The most common mapping error is to treat “mind” here as merely one’s stream of conscious thoughts. “Neither mind” does not mean “stop thinking,” suppress emotion, become blank, or behave without reflection. Nor does it mean that the practical distinctions among attention, memory, intention, and perception vanish. The target is the grasping that makes “mind” into an independently existing essence or final refuge.
A similar pattern appears in intimate relationships. One partner thinks, “If you truly loved me, you would stabilize my sense of worth.” “Mind itself is Buddha” redirects the person from demanding salvation from the partner toward seeing the fear and grasping alive in the present encounter. “Neither mind nor Buddha” then prevents that inward turn from becoming narcissistic spiritual isolation: “Everything is merely my mind, so your pain is irrelevant.” The partner’s experience cannot be reduced to an object inside one’s private consciousness. Freedom from fixed selfhood should deepen accountability and listening, not cancel them.
In parenting, the same teaching can expose the image of the “perfect parent.” One first seeks validation through the child; then one may seek a permanently calm “Buddha-mind” that never becomes frustrated. “Neither mind nor Buddha” releases the demand to maintain this sanctified identity. What remains is more modest and more demanding: notice irritation, refrain from harmful speech where possible, repair harm when one fails, and respond to the child actually present rather than to an idealized story about oneself.
Why contemporary people need it
Contemporary life constantly converts experience into identity. Recommendation systems learn from clicks and return a portrait of “what you like.” Workplaces quantify performance. Social platforms reward stable, recognizable personas. Self-improvement industries encourage us to monitor sleep, attention, fitness, productivity, and emotional regulation. These tools can be useful, but their measurements readily harden into a verdict: this profile is what I am.
“Neither mind nor Buddha” challenges this hardening. A behavioural profile is not a whole person. A recurring thought is not an essence. A diagnosis, personality type, political identity, meditation experience, or productivity score may disclose patterns without becoming an ultimate self-definition.
Artificial intelligence offers a useful but limited comparison. A model can produce coherent language without there being, inside each sentence, a little author who individually stores and selects every phrase. This can help loosen the intuitive picture of mind as a tiny controller sitting behind experience. But the comparison must stop there. Questions about consciousness, embodiment, subjective experience, and the capacities of artificial systems remain philosophically and scientifically contested. AI does not prove Buddhist teachings, and Buddhist analyses of attachment are not reducible to computational theories.
The saying also protects spiritual life from branding. “Awakened,” “mindful,” “nondual,” and “conscious” can become premium identities. A person may become attached not only to being admired but to being admired as someone who has transcended the need for admiration. “Neither Buddha” is especially sharp here. The image of oneself as spiritually advanced may be more difficult to relinquish than an openly worldly ambition because it can disguise self-protection as wisdom.
More deeply, the saying addresses the recursive nature of grasping. The mind can appropriate anything used to expose it:
- It can turn non-self into the identity “I am someone who has no ego.” - It can turn emptiness into the belief that nothing matters. - It can turn presence into a state that must be continuously maintained. - It can turn letting go into a performance of detachment. - It can turn “neither mind nor Buddha” into a superior doctrine with which to dismiss devotional practice, ethics, study, or other practitioners.
This is why Chan distinguishes a “living phrase” (*huoju*, 活句) from a “dead phrase” (*siju*, 死句). Dahui says:
“Students of the Way must investigate the living phrase, not the dead phrase. Realized under the living phrase, it is never forgotten through endless ages; realized under the dead phrase, one cannot even save oneself.” —*Dahui Pujue chanshi yulu* (《大慧普覺禪師語錄》)
The distinction is not simply between two sets of words. The very phrase “neither mind nor Buddha” becomes dead when stored as an explanation, repeated as a password, or used to avoid direct examination. It is alive when it cuts through the fixation operating now. Yuanwu goes further and refuses to let the student congratulate himself for calling “neither mind nor Buddha” a living phrase: all language, once grasped, becomes dead.
Its place in the path is therefore neither at the beginning nor exclusively at the end. At the beginning, it warns us not to objectify the goal. In sustained practice, it removes attachment to experiences and interpretations. At mature stages, it prevents realization from becoming an attainment owned by someone. Throughout, however, it does not replace ethical discipline, meditative cultivation, compassion, or wisdom. A deconstructive saying cannot serve as an excuse to bypass the training through which greed, hatred, and delusion become visible and workable.
The liberation toward which it points is not the achievement of a perfectly blank mind. It is increasing freedom from compulsive appropriation: experience occurs without every event having to establish who “I” am; teachings guide without becoming ideological property; compassionate action becomes possible without requiring a sacred self-image in return.
Common misreadings and clarifications
1. “It means there is literally no mind and no Buddha.”
That converts a therapeutic negation into an ontological creed. The records themselves refuse this move. Yuanwu asks, in effect: everyone plainly acts through what is called mind, so why speak of “no mind”? The question forces us to distinguish conventional use from ultimate reification. Conventionally, we speak meaningfully of minds, Buddhas, people, intentions, and practices. “Neither” denies that these names disclose fixed, independently existing essences.
2. “It overturns ‘mind itself is Buddha,’ so the later statement is more advanced and more true.”
The child-and-crying exchange does present a pedagogical sequence, but it does not establish a hierarchy of dogmas. “Mind itself is Buddha” can be liberating where someone seeks Buddha externally. “Neither mind nor Buddha” can be liberating where someone has reified mind or Buddha. Either can be wrong when applied as a fixed answer. Hence Dahui’s “both right; both not right.”
3. “Mind itself is Buddha means every thought and impulse is enlightened.”
This confuses non-separation from the field of practice with moral endorsement of everything arising in it. Anger, greed, and delusion need not be excluded from awareness before practice begins, but harmful intentions remain harmful and karmically consequential. “This very mind” removes the fantasy of an awakening imported from elsewhere; it does not canonize every habit.
4. “Neither mind” means thought suppression or a trance without mental activity.
The expression does not prescribe cognitive blankness. Trying to eliminate thought can itself become a powerful attachment to a preferred state. The issue is not whether thoughts appear but whether they are grasped as self, possession, final truth, or spiritual failure.
5. “Neither Buddha” rejects Buddhism, devotion, or the reality of awakening.”
The target is attachment to Buddha as an objectified external saviour or an identity one can possess. The saying arises within Buddhist practice and serves liberation from clinging. It does not ridicule reverence or eliminate the conventional meaning of buddhahood. It asks whether one’s idea of Buddha opens the hand or tightens it.
6. “Everything is mind, so other people and the external world are merely my projection.”
That is a serious narrowing of the teaching. Neither “mind itself is Buddha” nor “neither mind nor Buddha” licenses solipsism. The expressions address the practitioner’s grasping; they do not reduce other beings to content inside an individual ego. A supposed insight that makes another person’s suffering less worthy of care has missed the liberative function of the teaching.
7. “If no formulation is ultimately correct, words and doctrines are pointless.”
The crying child was helped by words. Medicine matters precisely because conditions matter. A teaching need not possess an independent, eternal essence in order to be effective. The error is not using language but demanding that a useful expression become an unchanging absolute.
8. “The negation itself is the final truth.”
This is the central danger. Yuanwu says to put “neither mind nor Buddha” aside. Damei refuses to be turned around by Mazu’s new wording. Dahui warns against being manipulated by the three sayings. Once negation has released the fixation, carrying it as a badge recreates the very bondage it was meant to undo.
9. “Non-attachment means indifference.”
Indifference is often attachment wearing armour: one withdraws to protect a threatened self. Genuine non-grasping makes room for a more accurate response. Because one need not defend a fixed identity at every moment, one can apologize, change course, endure discomfort, hear criticism, and care for another without converting care into ownership.
10. “Understanding the logic is the same as seeing through the attachment.”
One can explain provisional language, emptiness, living phrases, and nonduality while remaining deeply governed by the need to be right. Chan’s suspicion of conceptual fixation does not condemn understanding; it asks understanding to become self-applying. At the moment of insult, envy, fear, or spiritual pride, can the supposed knower be found as the fixed thing one is defending? Can the teaching work there, before it hardens into commentary?
The heart of *fei xin fei Fo* is therefore not a dramatic “No” spoken against mind, Buddha, or the world. It is a compassionate refusal to let any name—even the holiest name—become a prison. “Mind itself is Buddha” calls us home from searching elsewhere. “Neither mind nor Buddha” prevents us from turning home into a possession. “Not mind, not Buddha, not a thing” removes the last imagined ground beneath the one who wants certainty.
Then even these words must be put down. What remains is not a doctrinal vacuum, but the ordinary work of liberation: seeing grasping as it forms, not building a self out of it, and responding to the life before us with clarity and care.
