The case in full
Blue Cliff Record (Biyán Lù, 碧巖錄) Case 1, compiled by Yuánwù Kèqín (圓悟克勤, 1063–1135): 舉。梁武帝問達磨大師。如何是聖諦第一義。磨云。廓然無聖。帝曰。對朕者誰。磨云。不識。帝不契。 "Emperor Wu of Liang asked the great master Bodhidharma: 'What is the highest meaning of the holy truth?' Bodhidharma said: 'Vast emptiness, nothing holy.' The Emperor said: 'Who is it that stands before me?' Bodhidharma said: 'I don't know.' The Emperor did not catch it." The "no merit" exchange precedes this in other sources. The Platform Sūtra (Huìnéng, 6th c.) preserves the fuller version: Emperor Wu asks about his merit from building temples, copying sūtras, supporting monks. Bodhidharma: "No merit" (並無功德). Emperor Wu: "Why no merit?" Bodhidharma: "These are small causes of human and heavenly results — impure to their root."
Why "no merit" was scandalous
Emperor Wu of Liang was not a casual Buddhist. His patronage was massive: hundreds of monasteries built, thousands of sūtras copied and distributed, lavish state support for the Sangha, and personal ordination rituals. By 6th-century Chinese Buddhist standards, he was its most important lay supporter. The accepted understanding — then as now — was that such acts produce merit (功德, gōngdé), which conditions favorable rebirth, favorable circumstances, and eventual progress toward awakening. This understanding came directly from Indian Mahāyāna sūtras and was universally taught. Bodhidharma's "no merit" is a direct refutation of what every Buddhist teacher in China would have said. It is more radical than Zhàozhōu's "Mu" because Emperor Wu is not asking a subtle doctrinal question — he is stating the obvious. Bodhidharma's answer denies the obvious. This is what makes the case foundational: it establishes, at the very opening of the Chán line in China, that Chán operates from a position that cannot be built on accumulation logic.
What "no merit" actually means
Bodhidharma is not saying: (a) patronage is bad, (b) Emperor Wu's motives were impure, (c) Buddhism doesn't work. Each of these would be a standard critique from within the accumulation framework — "you did good things but your motives were impure" — and would be instantly recognizable to Emperor Wu. He could have processed and responded to any of them. Bodhidharma is saying something the framework cannot process: the very activity of "accumulating merit" is already a misunderstanding of what practice is. Merit-accumulation logic treats Buddha-nature as something to acquire, practice as investment, awakening as payoff. These are all framework-confusions. No amount of temple-building converts a framework-confusion into awakening, because the framework-confusion IS the thing that needs to drop. The "no" in "no merit" isn't claiming the merit is zero rather than high. It is refusing to play the merit-counting game at all. This is why Emperor Wu "does not catch it" — he continues to operate within the framework and cannot hear an answer that refuses it.
The second exchange: "vast emptiness, nothing holy"
Emperor Wu, trying to recover, asks the standard catechism question: what is the highest meaning of the holy truth? Bodhidharma: "Vast emptiness, nothing holy." This is the same move in a different register. If there were a "holy truth" that was itself holy, Chán would be another variety of religious accumulation — just subtler. Bodhidharma denies this too. The emptiness is not holy. The emptiness is not an alternative-object-to-be-valued. It is empty even of being the-thing-that-is-valuable. This is the Mādhyamaka move: śūnyatā is empty too (śūnyatā-śūnyatā, emptiness of emptiness). Nāgārjuna formalized this philosophically in the 2nd century; Bodhidharma is reported to have used it as direct teaching in the 6th. Emperor Wu's next question — "Who is it that stands before me?" — is a last attempt at handling. He is asking Bodhidharma to identify himself as a holy personage, which would preserve at least the teacher-as-holy frame. Bodhidharma: "I don't know." Not false humility. The "I" that would be a holy personage — a great teacher from India, twenty-eighth patriarch, carrier of special transmission — doesn't exist as a substantial thing. Bodhidharma truly doesn't know what "I" Emperor Wu is asking about. The meeting fails. Bodhidharma leaves, crosses the Yangtze (legendarily on a single reed), and sits for nine years facing a wall at Shaolin. Chán begins.
Why this kōan matters for modern practitioners
Meditation-for-benefits discourse recreates Emperor Wu's framework exactly. "Meditate and you'll be more productive." "Mindfulness reduces cortisol." "Zen improves executive function." Each of these is an accumulation-logic statement: do this practice, receive this benefit. This is not false — the benefits are real and empirically measurable. But they are "small causes of human and heavenly results — impure to their root" in Bodhidharma's sense. They do not touch what practice actually is. A practitioner who meditates primarily for benefits has reinvented Emperor Wu's framework in secular form. The benefits will come, but the fundamental cognitive operation — I am accumulating something through this — reinforces the self-structure that practice is, at depth, designed to dismantle. The kōan is not asking you to stop meditating. It is asking you to notice when meditation is being held as accumulation, and to drop that holding while continuing to sit. This is harder than it sounds. The holding is subtle — it hides in the checking of apps, the counting of streaks, the "I've been meditating for three years now" identity consolidation. Bodhidharma's "no merit" is pointed at exactly these subtle holdings. If they cannot drop, the practice stays inside Emperor Wu's framework regardless of how many temples you build.
A practical exercise
For one week: 1. Do not count sits, log time, track streaks, or mention to anyone that you've been meditating. 2. Do not make any claim about practice progress, even internally. 3. Do not plan practice in advance; sit when the moment permits and do not sit when it doesn't. 4. Notice every accumulation move that arises — the urge to count, to plan, to identify, to narrate. After seven days, observe what you find. Most practitioners discover they have been practicing substantially for the accumulation dimension — and that the practice itself has been getting smaller under the accumulation apparatus. The week is not a recommended permanent mode. It is a diagnostic tool showing how much of practice has been Emperor Wu.
