Part Five · The Three Wheels Empty · Prajñā, Honed to Its Sharpest

Part Four followed the great treatises of the Mahāyāna and laid the matter of "the three wheels empty" wide open, talked it through to the bottom. That is what treatises are good at: breaking the reasoning apart until it is perfectly clear, so that your head understands.

Part Five steps from the treatises that explain into the sūtras that hone this same matter to its sharpest edge—and sing it most movingly—the prajñā sūtras. In the Chinese world, almost everyone has heard a few of their lines.

Three chapters, three sūtras, three angles.

The first chapter: the Diamond Sūtra. It gives you no long analysis—only one light phrase, "giving without abiding in marks": when you give, the mind does not stop on any single mark. What it tells you is how to give: abide in nothing.

The second chapter: the Heart Sūtra. The shortest and most widely known of them all—and yet from beginning to end it never once says the word "giving." That silence is itself a teaching of the deepest kind. What it tells you is the condition under which giving becomes giving—prajñā. And it is precisely in this chapter that the word this book faces, "crossing over," will rise to the surface at last: "saw that the five skandhas are empty and crossed over all suffering and distress." Loosen the hand that clenches "mine," that clenches "I am giving," until there is nowhere left to abide—and that loosening is the crossing.

The third chapter: the Great Prajñāpāramitā Sūtra, a vast work of six hundred fascicles. It is the very opposite of the Heart Sūtra: it says "giving" over and over again—yet every time it says it, the word comes wrapped in emptiness. What it tells you is where giving leads: giving is the first step of the whole road, and prajñā is the pair of eyes that lets this road see its own direction.

The three chapters together: how to give (non-abiding), why giving is possible at all (emptiness), and where giving goes (all-knowledge). This is where "the three wheels empty" is honed to its sharpest—and where losing the "I" cuts keenest.

We begin with the Diamond Sūtra, and its phrase "giving without abiding in marks."
