Reading Map · Nine Stretches of Road, One Precept
This book is a road.
On a long walk, it steadies you to have a map in your hand—to know which stretch you are on, what lies ahead, and what this stretch is for. This reading map is the map of that road.
The book has nine parts and thirty chapters, plus eight short "transitions" between the nine stretches of road. The road sets out from that one question in the Sāvatthī park—"What is the meaning of keeping the precepts?"—and walks all the way to the "precept as teacher" of today. But whichever stretch you are on, what walks this road is always the same one thing—the precept: how it grows from a list outside into an ability in the body, into a seed in the heart, until even the mark is set down and it stands as a complete circle, falling at the last back into the life of every day.
Below, I will point out the nine stretches of road to you, one by one. You need not memorize them; a sense of direction in your heart is enough.
The Shape of the Road
The first three parts (Parts One through Three) are the roots: first the word "precept" is made clear in its definition (the Pāli); then we watch how it is handed, rule by rule, into the hands of living people (the Āgamas); then we watch how, person by person and case by case, it grows into a rigorous Vinaya (the Vinaya canon). These three parts lie closest to daily life, and are planted the firmest.
The middle two parts (Parts Four and Five) are the depths: the Mahāyāna stretches the precept wide—stretches it onto the mind; the patriarchs of the Chinese land press the question "at the moment of receiving the precepts, what is new in body and mind," and the answer reaches straight into the deepest place of the mind. This is the densest stretch of doctrine in the whole book; walk it slowly.
The three parts after that (Parts Six through Eight) are the heights: the vow-power of the Buddha Bhaiṣajyaguru guards the conditions for those who keep precepts; prajñā sets down even the mark of "keeping the precepts"; and at the last, three great sūtras establish the precept as a complete circle—ground, gate, form, and stage.
The last part (Part Nine) is the road home: bringing the whole road back to today, back into your daily use.
Nine stretches of road, one main line: the precept grows from rules into an ability, condenses from ability into the precept-substance, sets down the mark from the precept-substance, stands complete where the mark is empty, and from completeness falls back into daily use. This main line answers to that one word: "not"—in the Heart Sūtra's "neither arising nor ceasing"—after the giving gate has loosened the hand and the repentance gate has washed the karma clean, you receive a new boundary that guards you.
The Nine Stretches, One by One
Part One · Pāli Roots · What the Precept First Looked Like (four chapters)
The start of the road: going back to the root of the word "precept."
The first chapter, "The Precept Carries Three Things," opens the book with Ānanda's question, "What is the meaning of keeping the precepts?", then lays the word "precept" open—beneath it, it carries three things with three different kinds of work. The second chapter, "The Fourth Factor of Entering the Stream," watches a dispute between two men of the Śākya clan, and the verdict the Buddha handed down with His own lips: the precept is the fourth thing in which one who has entered the stream is accomplished. The third chapter, "Recollecting the Precepts You Have Kept," watches how a practitioner invites the precepts he has himself fulfilled back into the heart, to recollect them. The fourth chapter, "When the Precept Is Pure, Concentration Comes of Itself," lays down the book's long foreshadowing—this road leads to concentration, and concentration is something that comes of itself.
Part Two · The Precept in the Āgamas · A Precept Handed into Human Hands (four chapters)
From definition, into the field—how the precept is handed, rule by rule, into the hands of living people.
The first chapter, "Three Stretches of the Great Road Are the Precept," looks at the eight limbs of the noble eightfold path and sees that three of them are themselves the precept. The second chapter, "The Five Precepts: Where Each Line Is Drawn," lays open the five precepts everyone knows best, and looks at where each one's line is drawn. The third chapter, "Borrowing a Day and a Night to Learn Leaving Home Once," looks at that most ingenious of arrangements, the eight-precept uposatha. The fourth chapter, "The Fragrance That Travels Against the Wind," looks at what a precept actually kept gives off in the world.
Part Three · Three Vinaya Lineages · A Vinaya That Grew (three chapters)
Between the precepts scattered through the sūtras and a Vinaya recited fortnightly, there stands a gate.
The first chapter, "How the First Precept Was Laid Down," returns to Vesālī—to Sudinna, the man and his deed, and to the ten purposes the Buddha laid down with His own lips: the Vinaya grew, person by person and case by case, like case law, not like statutes handed down from heaven. The second chapter, "One Vinaya, Passed Down into Five Houses," watches this living code grow, along trade routes and through translation halls, into five transmitted recensions—their items differing here and there, their shared core not moving by a thread. The third chapter, "Two Storms," watches the Saṅgha pass through one breaking and one deliberation, and the thousand-year rule that the deliberation settled.
Part Four · The Mahāyāna Turn · The Precept, Laid Out to the World of Beings (four chapters)
The Vinaya can judge deeds, but not the arising of intent; it can hold the saṅgha-boundary, but cannot light what lies outside the wall. The Mahāyāna's answer arrives.
The first chapter, "Upāli's New Question," hears the venerable one foremost in upholding the Vinaya ask a question he himself cannot answer—and from it rise the three clusters of pure precepts: beyond stopping evil, there is also cultivating good and delivering beings. The second chapter, "Transgression Unobtainable, the Precept Unbreakable," watches what the precept looks like kept to its utmost in prajñā—a poison-dragon, with the one-day precepts, keeping those eight words unto death. The third chapter, "Nine Kinds of Śīla, One Completed Map," watches the Yogācārabhūmi-śāstra draw the bodhisattva precepts into a map whose end joins its beginning. The fourth chapter, "A Thousand Li Without a Preceptor: Self-Vow Before the Buddha-Image," watches how such a precept is received—and once received, it is not lost unto the very end of future time.
Part Five · The Precept-Substance · After Reception, What Is New in Body and Mind (three chapters)
The deepest layer of the whole book: the Chinese Vinaya school's learning of the precept-substance.
The first chapter, "At the Moment of Reception, What Was Received," hears the three answers—form-dharma? neither form nor mind? a seed?—then watches how Vinaya Master Daoxuan judges. The second chapter, "First Raise the Perimeter Wall, Then Build the House," meets the thousand-year standard text that holds this learning up, the Xingshichao: receiving is the perimeter wall; following is the house; receiving and following must sustain each other. The third chapter, "The Depths of a Single Seed," walks into the place where that seed lives—the storehouse of the eighth consciousness, the shadow of the seventh, and the homecoming of the transformation of the basis.
Part Six · Bhaiṣajyaguru's Twelve Vows · Guarding the Conditions of the One Who Keeps Precepts (two chapters)
What of the one who stumbles? The person who cannot keep the precepts may not be lacking in will.
The first chapter, "Twelve Vows That Guard the Conditions for Keeping Precepts," watches how the twelve great vows of the Buddha Bhaiṣajyaguru guard, for the one who keeps precepts, one thing after another—body, faculties, food, clothing, circumstance: the precept-vow at the center, the other eleven vows as its foundation. The second chapter, "A Ladder, or a Piece of Level Ground," asks whether the twelve vows are, in the end, a ladder climbing upward, or a piece of ground that holds a person up.
Part Seven · Prajñā's Sign-less Precept · A Precept That Sets Up No Mark (three chapters)
Six parts have made the precept ever more solid; the seventh part sets down the "mark" of it all.
The first chapter, "The Silence of the Diamond Sūtra," solves a riddle—why, in the most widely circulated Diamond Sūtra, the word "precept" appears only once in the whole text. The second chapter, "Remove It Directly, Do Not Perturb the Mind," watches the sign-less precept land on two bhikṣus who had broken the precepts and dared not face the Buddha—those eight words of Vimalakīrti's are the deepest line in the learning of repentance. The third chapter, "The Three Wheels Are Pure," sets down all at once the keeper, the precept, and the protected being—empty all the way down, and the practice is still there.
Part Eight · The Complete Precept · The Precept as the Ground of Concentration (four chapters)
The last scriptural stretch of the road for the learning of the precept: three great sūtras, four positions.
The first chapter, "Sand Cannot Be Steamed into Rice," goes up to the Śūraṅgama assembly to hear the Buddha gather all practice into three phrases—gathering in the mind is what I call the precept; from the precept concentration is born; from concentration wisdom is unveiled—and the four pure and clear instructions, the foundation for entering concentration of which not one can be spared. The second chapter, "The Precept Is Also a Gate," returns to the same sūtra's chapter on perfect penetration—the precept is not only the foundation; keeping the precept is itself a gate into concentration, standing equal with all the other gates. The third chapter, "To Abide In, Not to Keep Away From," goes to the Lotus assembly to see what form the precept takes inside this gate—"to abide in," not "to keep away from." The fourth chapter, "One Precept, Held to the Buddha-Ground," climbs the ten grounds of the Huayan—the same one precept, held from effortful guarding to acting of its own nature, from the measure of a śrāvaka to the measure of the buddha-ground.
Part Nine · The Modern Diagnosis · The Precept as Teacher (three chapters)
Bringing the whole road back to today.
The first chapter, "Two Illnesses, One Root," diagnoses the two illnesses of precept-keeping today—one preached soft: keeping the feeling, dropping the form; one held hard: keeping the form, dropping the heart—two illnesses on one same root. The second chapter, "'I Didn't Say That,'" walks to where the illness bites deepest, the karma of speech: in an age when machines too can write words, the ancient scale of the false-speech precept still weighs that one moment of mind. The third chapter, "The Precept as Teacher," returns to the middle of the night between the twin sāla trees, to hear the Buddha's final exhortation—and to answer the book's last question: when the reasoning is all spoken, where does the precept land? It lands in doing it, day by day.
When Part Nine is read, the road is fully walked.
How to Walk This Road
Walking it in order is best. This is a road with a beginning and an end. The "transitions" between the parts are there to carry your breath—each gathers in what the last part won, points to what it could not yet handle, and hands you gently into the next. Do not skip them.
You may also pick and choose. The first three parts lie closest to daily life; if you want a steady place to set your hand, begin there. Part Five is the densest in doctrine; do not hurry—walk it stretch by stretch.
If you are impatient, read the final chapter first. If all you want to know is "then what do I actually do?", turn first to the last chapter, "The Precept as Teacher." It gathers the whole road into four words. When you have read it and come back, you will understand what stands behind those four words.
The catalog numbers and the textual scholarship are all in the appendices. All the catalog numbers, fascicle numbers, and original Pāli and Sanskrit words for the sūtras, Vinaya texts, and treatises this book quotes are gathered into Appendix A and Appendix C at the back. None of it is laid in the body text, so nothing need trip your feet as you read; whatever you wish to look into closely, the appendices hold.
The map ends here. Nine stretches of road, one precept.
We set out from the first stretch of the road—to hear Ānanda ask that one question: What is the meaning of keeping the precepts?
