Part Two · The Sotāpanna · The Step from Ordinary to Noble
Part One set up the ruler: the fruits are measured by severance, and every fruit has an approach and a fruit. Now, stand before the first wall.
This station is called sotāpanna—stream-entry. On the whole road, it carries the greatest weight: the three stations after it are noble ones going deeper into nobility, but this one station is an ordinary person becoming noble. The question so many practitioners carry for a lifetime—"have I actually entered the door"—is asked of exactly this place.
Part Two has two chapters. Chapter one looks at which three fetters stream-entry severs, and at a surprising fact: the first to fall are not the coarsest—craving and ill will stand further down the line, and what falls first are identity-view, doubt, and the grasping of rites. Why? Because these three block not "going far," but "getting onto the right road" at all. The chapter also takes the name seriously: entered into what stream? The Buddha once examined Sāriputta on exactly this, and the answer stands in the sutta.
Chapter two looks at the two weighty sentences stream-entry carries with it: no falling to the lower destinies; at most seven returns, then the end of suffering. They sound like certificates of guarantee; chapter two shows that they are no one's promise, but the corollaries of severance itself—certainty is not given, it is entailed.
Direction, and certainty. The whole of this station is these two things. We enter chapter one.
