एयं सुयं भगवया, धम्मं जाणह पंडिया।
This has been heard from the Blessed One — know the teaching, O learned ones.
Chapter 16 is the closing chapter of Book 1 of the Sutrakritanga, and its function is the seal — not a new teaching but the affirmation and summary of everything that has been transmitted across the preceding fifteen chapters. The opening phrase is deliberately formal: "This has been heard from the Blessed One." In the Jain tradition, the phrase marks the boundary between what was directly received from the Tirthankara and what might be inference, commentary, or later addition. Everything in Book 1 falls within this boundary — it is the transmitted teaching of Mahavira, carried through his principal disciple Sudharman and passed down through the monastic chain of transmission. The Jain tradition treats this chain as a sacred trust. Each disciple who received the teaching and passed it forward was responsible for preserving it without distortion — not reinterpreting it, not embellishing it, not simplifying it for convenience, but transmitting exactly what was heard. "Know the teaching, O learned ones" — the address to the learned ones is an address to those in each generation who carry this responsibility. Being learned in the Jain sense means being capable of receiving the teaching accurately and transmitting it faithfully. This is not just a matter of scholarship — it is a matter of spiritual integrity. The teaching's survival depends on the quality of those who receive and pass it on.
The simple version: This teaching comes from the one who knew it from direct experience. The chain of transmission matters because it guarantees that what was heard was preserved accurately.
