What this concept is saying
Jiānzhōng zhì 兼中至—roughly, “the arrival within the mutual inclusion”—is the fourth position in the Caodong school’s Five Ranks of the Relative and the Absolute (*piānzhèng wǔwèi* 偏正五位). Its central meaning is “essence and function arrive together” (*tǐ-yòng bìng zhì* 體用並至): reality as such and its concrete activity are fully present at once, without collapsing into either side.
A textual caution is useful at the outset. The principal sources here—the *Recorded Sayings of Chan Master Dongshan Liangjie of Ruizhou* (*Ruìzhōu Dòngshān Liángjiè Chánshī Yǔlù* 瑞州洞山良价禪師語錄) and the later Chan anthology *Eyes of Humans and Gods* (*Réntiān Yǎnmù* 人天眼目)—are Chan records and compilations, not sutras spoken by the Buddha. Their verses should therefore be attributed to those records, not introduced generically as “the sutra says.”
The Five Ranks provide several standpoints from which awakening and the phenomenal world may be understood:
- 正中偏 (*zhèngzhōng piān*, “the relative within the absolute”): function arises from essence—*體起用*. - 偏中正 (*piānzhōng zhèng*, “the absolute within the relative”): function returns to or discloses essence—*用歸體*. - 正中來 (*zhèngzhōng lái*, “coming from within the absolute”): awakening turns freely toward activity; absolute and relative are already interacting. - 兼中至 (*jiānzhōng zhì*): essence and function arrive together—*體用並至*. - 兼中到 (*jiānzhōng dào*): essence and function are both effaced as separately graspable positions—*體用俱泯*.
These are not five substances or five worlds. Nor should they be made into a rigid ladder on which one collects spiritual promotions. They are interrelated perspectives exposing progressively subtler forms of attachment: attachment to phenomena, attachment to emptiness, attachment to the movement between them, and finally attachment even to the idea that “absolute” and “relative” are two things that must somehow be united.
In this vocabulary, 正 (*zhèng*, “upright,” often interpreted as the absolute) points toward emptiness, equality, or reality prior to conceptual division. 偏 (*piān*, “inclined,” conventionally the relative) points toward distinctions, events, roles, causes, effects, and concrete appearances. These translations are only aids. 正 is not a metaphysical substance hiding behind the world, while 偏 does not mean false or inferior. The relative is precisely where the absolute functions; the absolute is never found apart from particular conditions.
Similarly, 體 (*tǐ*, essence or body) does not mean an eternal soul or changeless cosmic material. It names reality considered in its undivided character. 用 (*yòng*, function or activity) is that same reality appearing as seeing, hearing, answering, working, choosing, suffering, helping, and adapting to conditions. Jiānzhōng zhì is therefore not the joining of two originally separate entities. It is the realization that they were never separable—while still allowing each to retain its meaning.
That is the force of 兼, “including both,” and 至, “arriving”: neither side remains merely implicit. Emptiness does not remain a private inner serenity; it arrives as conduct. Activity does not lose itself in multiplicity; its groundless, ungraspable character is present within the activity itself.
The *Recorded Sayings of Dongshan* expresses the rank in three matched lines:
兩刃交鋒不須避。 好手猶如火裏蓮。 宛然自有沖天志。
A serviceable translation is:
When two blades cross, there is no need to evade. A skilled hand is like a lotus blooming in fire. Clearly it possesses its own sky-soaring resolve.
The three images should not be flattened into one vague message about courage. Each marks a distinct aspect of the rank.
1. “Two blades cross; there is no need to evade.”
The two blades evoke the sharp encounter of 正 and 偏, essence and function, equality and distinction. At this rank one does not escape the relative by retreating into emptiness, nor abandon emptiness in order to manage worldly affairs. Both edges are completely present.
“不須避”—“there is no need to evade”—does not mean recklessly seeking conflict. It means that when reality presents an irreducible demand, practice does not create an inner refuge from which one refuses the demand. There is no separate observer keeping awakening safe from life.
2. “A skilled hand is like a lotus in fire.”
The 好手 (*hǎoshǒu*, skilled practitioner) can enter intense conditions without either being consumed by them or becoming numb to them. The lotus does not bloom because the fire has first been extinguished. It blooms in the fire.
This is more demanding than ordinary calm. Calm maintained only while no one contradicts us is conditional composure. The fire-lotus represents freedom functioning amid pressure, pain, disagreement, and complexity. Yet it does not imply invulnerability or the suppression of emotion. A practitioner may feel grief, fear, or anger clearly. What is absent is the compulsive construction of a fixed self around them.
3. “Clearly it possesses its own sky-soaring resolve.”
“宛然自有” suggests something unmistakably present, not mechanically manufactured from outside. The “sky-soaring resolve” is the unobstructed vitality of awakened functioning: wisdom naturally tends toward expression, and compassion naturally tends toward response.
This should not be converted into a doctrine of an eternal inner essence. In Chan idiom, saying that the resolve is “inherently present” cuts through the belief that awakening is a foreign object acquired by the ego. It does not establish a permanent self beneath experience. Nor does it excuse the lack of cultivation: what is not acquired from outside must nevertheless be realized, embodied, and tested in conditions.
*Eyes of Humans and Gods* states the doctrinal point succinctly:
正中偏者。體起用也。偏中正者。用歸體也。兼中至。體用並至也。兼中到。體用俱泯也。
That is: in the first rank, essence gives rise to function; in the second, function returns to essence; in jiānzhōng zhì, essence and function arrive together; in the final rank, both are effaced as separately held positions. The received wording is available in the [*Recorded Sayings of Dongshan*](https://zh.wikisource.org/zh/%E7%91%9E%E5%B7%9E%E6%B4%9E%E5%B1%B1%E8%89%AF%E4%BB%B7%E7%A6%AA%E5%B8%AB%E8%AA%9E%E9%8C%84) and the [Chinese text of *Eyes of Humans and Gods*](https://baus-ebs.org/sutra/fan-read/003/03-017.htm).
The same anthology correlates the rank with “neither existent nor nonexistent” (*fēi yǒu fēi wú* 非有非無) and “neither person nor environment is taken away” (*rén-jìng jù bù duó* 人境俱不奪). “Neither existent nor nonexistent” is not foggy indecision. The event exists conventionally: words have effects, pain hurts, promises matter. But neither the person nor the event exists as an independent, fixed entity. Consequently, “not taking away the person or environment” means that subject and situation are allowed to stand in their full conventional reality without being reified.
In the Five Ranks’ courtly symbolism, jiānzhōng zhì is described as the minister turning toward the sovereign and sharing the work: 臣向君共功. Read carefully, “sovereign” and “minister” do not legitimate worldly hierarchy. They are symbolic roles. The sovereign indicates the undivided source; the minister indicates differentiated functioning. At the fourth rank, functioning does not merely receive orders from an abstract principle. Source and activity accomplish the work together.
This places jiānzhōng zhì at a crucial point on the path of liberation. Early insight may reveal that thoughts, identities, and situations are empty of fixed selfhood. But one can then become attached to spaciousness, silence, detachment, or the identity of “one who sees through things.” Jiānzhōng zhì is the turning point at which realization must survive contact with the world. Emptiness must answer the email, apologize without self-protection, make the difficult decision, wash the bowl, and care for the suffering person before it.
A walkthrough in everyday life
Imagine an intimate relationship under strain. After a long day, your partner says, “You never listen to me. Everything is always about your work.” Immediately your body tightens, the mind prepares evidence for the defense, and a familiar identity appears: “I am the responsible one, and I am being unfairly accused.”
Here is how jiānzhōng zhì can be walked through without reducing it to a communication technique.
First, the two blades meet.
The concrete situation—the words spoken, your exhaustion, your partner’s expression, the history between you, the practical question of work—is the differentiated world of 偏, the relative. Nothing in the teaching permits you to dismiss it as “merely a projection.”
At the same time, when you look closely, no fixed attacker, victim, anger, or self can be found apart from changing sensations, memories, expectations, and conditions. This ungraspability is the aspect indicated by 正, the absolute or empty character of the event.
The common mapping error is to call your inner calm “the absolute” and your partner’s complaint “the relative.” That quietly makes enlightenment yours and delusion theirs. 正 and 偏 are not two people in the room. Both are dimensions of the entire encounter.
Nor is the body simply “function” while some pure awareness inside is “essence.” The tension in the chest, the sound of the complaint, awareness of it, the history that gives it meaning, and the possible response all arise dependently. Essence is not an invisible witness standing behind these events.
Second, you do not evade.
Evasion can take several forms. You might counterattack. You might become coldly silent. More subtly, you might tell yourself, “There is no self, so there is no one being hurt,” or “Everything is empty, so this argument does not matter.” The latter sounds Buddhist but uses emptiness to take away the person and the environment.
“不須避” means remaining available to both truths. The accusation is not an independently existing verdict on who you are; nevertheless, your partner may genuinely have been lonely. You do not have to protect a fixed self, and precisely for that reason you can investigate the concrete harm more honestly.
Third, the lotus blooms in the fire.
You feel the defensive heat without making it your sovereign. Instead of rehearsing a spiritual formula, you might say: “I can feel myself wanting to defend my intentions. But I want to understand what this week has been like for you. When did you feel most alone?”
This response is 用, function: speech, timing, attention, and ethical action. But it is not mere busyness or outward performance. Its freedom comes from 體: no fixed image of “me, the good partner” has to be preserved. Essence and function arrive together in the response.
The mapping mistake here would be to identify function with whatever action happens. A defensive insult is also an activity, but “function” in the mature sense of this rank is unobstructed functioning—not simply muscular movement, productivity, or spontaneous impulse. “I acted without thinking” is not proof of nonduality.
Fourth, sky-soaring resolve becomes concrete.
After listening, you may need to change your schedule, set a boundary with work, arrange childcare differently, or admit that you cannot make a promise. The “sky-soaring” quality is not emotional grandiosity. It is the freedom to respond without being trapped by the old self-story.
Perhaps the wisest response is tenderness; perhaps it is a firm refusal; perhaps it is seeking counselling. Nonduality does not prescribe one visible behavior. Its test is whether wisdom and circumstance are functioning together—without clinging to self, without erasing consequences, and without using principle to avoid relationship.
The same walk can occur while scrolling a phone. The algorithmically selected image, the desire it triggers, and the commercial system shaping attention belong to the fully differentiated relative. Their lack of fixed essence is the absolute aspect. Jiānzhōng zhì neither demonizes the feed as an alien power nor claims, “It is all empty, so it cannot affect me.” It sees conditioned influence clearly and acts: putting the phone down, continuing deliberately, or changing a setting. The act is not outside contemplation. It is contemplation arriving as function.
An AI analogy can help, within limits. A model’s architecture and parameters cannot be meaningfully separated from their functioning in a particular interaction; what the system is becomes visible through what it does under conditions. But this is only an analogy. Buddhist 體用 is not a computational theory, an AI model is not evidence for Chan awakening, and current debates about machine cognition do not establish the presence of realization or subjective awareness in machines.
Why contemporary people need it
Contemporary life repeatedly divides what jiānzhōng zhì holds together.
One division is between inner wellness and outer responsibility. Meditation can become a protected zone used to tolerate an unhealthy workplace, avoid a difficult conversation, or preserve a pleasant self-image. Jiānzhōng zhì asks a sharper question: does stillness arrive as truthful speech and responsive conduct? If it cannot enter the fire, it has not yet shown the freedom praised by the verse.
A second division is between principle and context. Public life often rewards absolute declarations, while actual care requires attention to particulars. “Everyone should be treated equally” expresses an important principle, but equal regard may require different concrete responses to different conditions. In the language of the Five Ranks, 正 without 偏 becomes abstraction; 偏 without 正 becomes fragmentation or favoritism. Their simultaneous arrival permits equality to function as intelligent responsiveness.
A third division is between authenticity and discipline. Contemporary culture may equate freedom with expressing whatever feeling arises. Jiānzhōng zhì points to a deeper spontaneity. The fire-lotus is not impulsiveness. It is responsiveness no longer organized around defending a fixed self. Such freedom generally requires long cultivation: ethical restraint, attention, repentance, patience, and repeated willingness to see one’s evasions.
A fourth division is between emptiness and compassion. If persons are empty of inherent existence, their suffering is not thereby unreal. On the contrary, because suffering arises through conditions, conditions can be understood and changed. Emptiness removes the imagined walls around beings; compassion is how that absence of separation functions. In jiānzhōng zhì, insight is not complete until it has hands.
This is why the fourth rank matters within the liberation path. It addresses a sophisticated attachment: the wish to possess awakening as a standpoint apart from ordinary life. The first freedom is seeing that phenomena cannot bind a fixed self. A deeper freedom is having no need to stand outside phenomena in order to remain free.
Still, jiānzhōng zhì is not presented as the final rank. “Essence and function arrive together” can leave a subtle observer congratulating itself for successfully integrating two sides. The fifth rank, 兼中到 (*jiānzhōng dào*), removes even that trace: essence and function are no longer maintained as two categories whose unity someone possesses. The fourth is the magnificent arrival of nondual functioning; the fifth releases attachment to the arrival itself.
Common misunderstandings and clarifications
“It means balancing two opposites.”
Not quite. Balance assumes two independently existing forces whose proportions must be managed. Jiānzhōng zhì points to mutual inclusion: essence is never found without function, and function never departs from essence. Practical balance may follow, but ontological nonseparation is the deeper point.
“The absolute is the real world; the relative is an illusion.”
This imports a two-world metaphysics into the Five Ranks. The absolute is not a superior realm behind appearances. An appearance is “relative” because it arises through relations and distinctions, not because it is nothing. Its emptiness and its concrete causal efficacy are simultaneous.
“Nonduality means distinctions no longer matter.”
That is one of the most dangerous errors. Empty praise and cruel speech do not have identical consequences. Medicine and poison remain distinguishable. Consent, responsibility, and power differences remain ethically decisive. Nonduality frees distinctions from reification; it does not abolish discernment.
“人境俱不奪 means neither I nor the world can be questioned.”
It means neither person nor environment is erased as a functioning conventional reality. It does not grant the ego and its interpretation absolute authority. Both person and environment are fully present precisely as conditioned and empty.
“The fire-lotus teaches emotional invulnerability.”
The verse praises freedom amid intensity, not the inability to be wounded. Refusing grief or bodily limits may be another form of evasion. A lotus in fire can appear as crying without self-entrapment, leaving a harmful situation, requesting help, or acknowledging that one’s present capacity is insufficient.
“大用現前不存軌則 means an awakened person is beyond rules.”
Hongzhi’s line, “the great function manifests before us, not preserving fixed tracks,” concerns freedom from mechanical patterns. It is not permission to ignore precepts or consequences. In Buddhist practice, claims of spontaneity that consistently benefit oneself and harm others deserve particular suspicion. Genuine flexibility remains answerable to compassion and causality.
“Its natural resolve means no practice is necessary.”
“Not acquired from outside” does not mean “already embodied in every habit.” Sunlight may be unobstructed in nature while a closed room remains dark. Practice does not manufacture awakening as an egoic possession; it exposes and relinquishes the grasping that prevents awakening from functioning.
“兼中至 was always the uncontested fourth-rank name.”
The received *Dongshan Record* lists the sequence as 正中偏, 偏中正, 正中來, 兼中至, 兼中到, placing 兼中至 fourth. But *Eyes of Humans and Gods* preserves Jiyin’s criticism that an earlier or alternative name, 偏中至 (*piānzhōng zhì*), had been changed to 兼中至. This is a genuine textual and interpretive variation, not something to conceal. The later name is especially congenial to the gloss *體用並至*, but one should not project that terminological uniformity backward without qualification.
“The five ranks are simply five chronological enlightenment levels.”
They can guide progressive training, but they also interpenetrate. A mature practitioner may display clarity in one circumstance and cling to emptiness in another. The ranks are best used as diagnostic mirrors, not spiritual titles. Asking “Which rank have I attained?” can preserve the very self-position that the ranks are designed to undo.
Jiānzhōng zhì finally asks something wonderfully practical: when no fixed self can be found, what does that freedom do here? If it retreats from the crossed blades, it is incomplete. If it becomes mere activity, it has lost its source. When emptiness is fully present as the particular response, and the particular response is free of self-grasping, the lotus blooms where one least expects it—in the fire itself.
