Rejoicing, and Two Supplications

Chengguan reads this vow as four concentric circles, deliberately ordered from the least to the most exalted: first the whole of every buddha's own path, from the first arousing of the aspiration through eons of literally giving away heads, eyes, hands, and feet, down to the distribution of their relics after death; then the ordinary merit of every being reborn anywhere across the six destinies; then the attainment of śrāvakas and pratyekabuddhas; then the vast, difficult cultivation of bodhisattvas. He explains the ordering as pedagogical rather than a claim that a buddha's merit is somehow last in importance — the text moves "from inferior to superior" precisely so that the vow ends on the note of greatest weight, having already established, at the bottom of the scale, that no good deed is too small to be included.

To convey how much is generated by rejoicing alone, without any deed of one's own, Chengguan cites two comparisons this vow's tradition inherited from elsewhere. The Mahāprajñāpāramitā Sūtra asks the reader to imagine splitting a single hair into a hundred strands, dipping one strand into the entire ocean, and drawing out one drop — the number of such drops in that ocean can, at least in principle, be counted; the merit of rejoicing in others' virtue cannot. And the Lotus Sūtra's "fiftieth person" parable is more extreme still: someone fifty people removed from ever hearing the sermon itself — who merely rejoices on catching a fragment of it, secondhand, from someone who heard it from someone who heard it — still generates merit that outstrips eighty years of giving every sentient being in four hundred myriad koṭis of world-systems every imaginable luxury. Chengguan's point in citing both is the same: rejoicing costs nothing but a change of heart toward what someone else has already done, and this vow treats that change of heart as inexhaustible merit in its own right.

Chengguan raises the objection this vow invites directly: in the perfect teaching, every sound in the universe is already the Dharma wheel turning, ceaselessly, whether anyone asks for it or not — so what could a "request" possibly add? His answer turns on where the obstruction actually lies. It is not that the Buddha's teaching needs to be started; it is that an ordinary mind, fixed on particular sounds and forms, is like an ear made deaf by too much music — unable to hear the single, all-pervading resonance beneath the noise. He quotes the Avataṃsaka's own chapter on the Buddha's manifestation: "knowing sound to be like an echo, one requests the turning of the Dharma wheel" — the request is not a summons addressed outward to a Buddha who might otherwise stay silent, but the very act of a mind clearing itself enough to finally hear what was never not being taught. He grounds this in the historical scene as well: at Deer Park, tradition holds it was Brahmā's own request that occasioned the first turning of the wheel for the five ascetics — not because the Buddha's realization required an audience's permission, but because the request itself is what makes a teaching land in the world it is spoken into.

Chengguan poses this vow's own hardest question before answering it: if a buddha's dharma-body is, by nature, always and everywhere present, what could it possibly mean to "request" that a buddha remain, as though presence were something a buddha might otherwise withhold? His answer draws on an image from the Avataṃsaka's chapter on the Buddha's manifestation: the sun rises and its reflection appears in every clean vessel of water at once, without exception; if the reflection fails to appear in one particular vessel, the fault lies with that vessel — cracked, or clouded — never with the sun, which has done nothing different. In exactly the same way, the Buddha's wisdom, like a sun, shines into the entire Dharma realm without gap or interruption; a being who cannot see the Buddha has not been abandoned by the Buddha, but is looking out through a mind too clouded or too broken to hold the reflection. On this reading, "requesting the buddhas to remain" is not a plea addressed outward at all — it is the vow to keep one's own mind clean enough, moment by moment, to go on seeing what was never actually absent. Chengguan draws the explicit parallel to the Vimalakīrti Sūtra's own teaching that a pure land is nothing other than a mind made pure.

He also cites, at length, the scene from the Nirvana Sūtra that stands behind this vow's language: light streaming from the Buddha's face at Kuśinagara, and the assembled beings' grief-stricken entreaty in verse — "like a calf that has lost its mother," "like a country with no king, its people starving" — begging him not to enter nirvana. Read alongside the vessel-and-reflection teaching, the two together give this vow its full weight: the grief is real and the language of loss is not dismissed, but the deeper teaching underneath it is that what looks like a buddha's departure is, from the buddha's own side, no departure at all — only a change in whether the world in front of him still has a clean enough vessel to catch the light.
