Dhammapada Chapter 12: Self

The Self chapter concentrates the Dhammapada's teaching on responsibility. Its keystone verse is a question and its own answer: self is the lord of self — what other lord could there be? With self well-tamed, one finds the lord that is hard to find (12.4). Hold yourself dear, then guard yourself well (12.1) — and the guarding has an order of operations: first establish yourself in what is proper, then instruct others; teach as you do, for the self is truly hard to tame (12.2–12.3).

The chapter's realism is bracing. Evil done by oneself, born of oneself, crushes the fool as a diamond grinds a gemstone (12.5); what is harmful is easy to do, while the beneficial and good is extremely hard (12.7). And its most quietly radical verse removes every proxy from the moral life: purity and impurity are personal — no one can purify another (12.9). Even the final counsel against self-neglect keeps the same axis: let no one neglect their own true welfare for another's, however great; know your own welfare clearly and be intent on it (12.10) — not as selfishness, but because a drowning person rescues no one.
