Transition ④ · From the Mahāyāna Turn to the Precept-Substance

Part Four has walked up to those four words—"mind as its substance"—and stopped. The page is about to turn.

This middle page is a breath.

With Part Four done, you hold a complete set of things in your hands. A new master map: the three clusters—stopping evil, cultivating good, carrying beings across—the Vinaya taken in intact as the first cluster, and the bodhisattva's every task contained within them. A ruler for testing: transgression unobtainable, and the precept unbreakable—the truer the emptiness, the steadier the keeping; the poison-dragon's one-day precepts held that ruler unto death. A completed map: the nine kinds of śīla, with the four qualities of the śīla of intrinsic nature as the root, re-purification after a breach drawn into the definition itself, the ring closing head to tail of its own accord. And a great building of reception: the three grades in their sequence; where within a thousand li there is no preceptor, one may receive by self-vow before the buddha-image; and once received, not lost even by transgression, unto the very end of future time.

This set of things establishes the Mahāyāna precept in full: its territory established out to the world of beings, its depth established down to the sign-less, its law of reception established so that everyone can receive.

Is it enough?

By the language of the Mahāyāna scriptures and treatises, yes. One who has aroused the aspiration practices by the three clusters, examines by the nine kinds, receives by the three grades—the practice-gate of the bodhisattva precepts stands complete.

But there is one word these scriptures and treatises use over and over without ever taking it apart to look.

Substance.

"Mind as its substance"—how satisfying to say; how deep, once you press the question. At the moment of reception, before the Buddhas of the ten directions, the three declarations completed—what exactly happened? That thing taken in and received into body and mind—the thing that from then on is "once received, not lost even by transgression, unto the very end of future time," the thing by which an ordinary man comes to "enter the rank of the buddhas"—what is it? Is it a kind of form-dharma, an invisible guard laid upon the body? A kind of mind-dharma, a force continuing thought after thought? Or a single seed, planted deep into the field of consciousness?

This is no idle metaphysics. It pulls on the most practical things: if the precept is form, is it there when the body breaks apart? If the precept is mind, is it there in sleep, in a faint, when an evil thought stands present? When a grave precept is broken, is that substance shattered—or covered in dust? And when one repents—what is being repented?

The Āgamas do not answer this question—they mind only the keeping. The Vinaya does not answer it—it minds only the judging. The Mahāyāna scriptures gave one sentence, "mind as its substance," and said no more. The ones who took this word apart head-on and built it into a discipline of learning were the Vinaya school of China—over several centuries its masters raised three schools' answers and argued three schools' debates, until, in the hands of the Vinaya master Daoxuan, it was gathered into the deepest hall of Chinese precept-learning: the doctrine of the precept-substance.

To understand the precept in the Chinese transmission, there is no way around this hall.
