Transition Four · From the Anāgāmin to the Fruit of Arahantship
Part Four is walked, and the road now runs outside the desire realm. Take stock.
The change of kind: the five lower fetters gathered and exhausted, the desire realm's binding at zero, "rebirth in the desire realm" stripped of its agent—no return. The three stations' rebirth-sentences in one line: not falling (the destination raised, within the realm), one return (the count reduced, within the realm), no return (across the realm)—one subtraction, two steps of quantity, then one of kind. The differentiation: past the crossing, the ways to nibbāna are five—in the interval, upon rebirth, with exertion, without exertion, upstream; one kind of spark from one iron, differing in when it goes out, never in size or rank. Fruit fixed by severance; journey fixed by conditions.
Now look at the last stretch of road.
The "remainder" the five roads sever has names: craving for form, craving for the formless, conceit, restlessness, ignorance—the five higher fetters. "Higher" is the binding of the higher realms: the first two bind a person to the form and formless realms—desire's craving exhausted, the craving for subtler modes of existence remains; the last three—conceit, restlessness, ignorance—are the three that wind deepest and hide best. Of the ten fetters these five stand last, not because they are lightest—precisely because they are finest. Coarse fetters show themselves, and the blade finds them; fine fetters grow flush against the mind, and the blade must be exact.
The next part is the last. But its shape differs from all four before it, and that should be said before the door.
At each of the four stations so far, the writing reached the fruit—severed, settled, then on to the next station. At this last station, the book writes only to the approach. Chapter one looks at the five higher fetters—where each of the last five walls is tied, and why they are the finest and hardest. Chapter two writes to the point where the taints are at the brink of exhaustion and the person stands on the threshold—and there, the pen stops.
Why stop? The word given at the end of Part One is honored here: what lies inside the door belongs to another volume. The freedom of mind and wisdom that opens when the taints are exhausted—the three knowledges, the six powers, the adornment of the both-ways liberated—is the view after arriving, and it belongs to this book's twin volume on the attainment axis. Walking writes the going; attainment writes the arrival. This volume's office is to bring a person to the threshold—not a step short, not a step past.
So the last part's two chapters: one for the walls, one for the stretch that reaches the threshold. When the fifth wall is torn to its end, the book ends—ends before the door opens.
The five finest walls are ahead. Go in.
