The teaching in one sentence
Watching a group of dreadlocked ascetics plunge repeatedly into the freezing Gayā river, believing “through this there is purity,” the Buddha responds with a verse stating flatly that purity doesn’t come from water at all, but from truth and principle.
Bathing against the winter cold
The scene is set with unusual sensory precision for this collection: “the cold spell when the snow falls in the January winter,” at Gayā Head, where “many dreadlocked ascetics plunged in and out of the Gayā river.” Alongside this repeated plunging, they also “served the sacred flame” — fire-worship paired with ritual bathing — all of it undertaken, the text tells us directly, in the belief that “through this there is purity.”
A silent witness, once again
As in Ud 1.6, there is no dialogue here at all. The Buddha “saw them plunging in and out,” and that observation alone is what prompts the verse. Two of the six discourses in this thread — this one and the Mahākassapa episode — share this structure: no question, no debate, simply a scene observed and a heartfelt saying spoken in response to it.
The verse's answer: truth and principle, not water
The verse could hardly be more direct: “purity doesn’t come from water, no matter how many people bathe there. One who has truth and principle, they are pure, they are brahmins.” It doesn’t deny that the ascetics are sincere, or soften the contrast for tact. It states the claim and its opposite side by side, in as few words as the verse allows.
A recurring canonical concern
The rejection of ritual bathing as a path to genuine purification is a concern that surfaces more than once in early Buddhist texts, generally aimed at the same underlying point this verse makes: that external practices, however sincerely performed, cannot substitute for an internal change of character. This discourse gives that broader concern one of its most compact statements — purity paired not with water but with the twin qualities of truth (sacca) and principle (dhamma).
Closing the six-discourse thread
With this discourse, the run that opened at Ud 1.4 comes to a close. Across six scenes — a muttering ascetic, ten approaching elders, an alms round among the poor, a taunting spirit, a former wife’s visit, and now a company of ritual bathers — the same claim has been tested against ritual utterance, birth, poverty, fear, family attachment, and now water itself. Each time, the verdict lands in the same place: on inner qualities, not external circumstance or practice.

The setting
§1So I have heard. At one time the Buddha was staying near Gayā on Gayā Head. Now at that time—during the cold spell when the snow falls in the January winter—many dreadlocked ascetics plunged in and out of the Gayā river. Plunging and showering, they served the sacred flame, thinking: “Through this there is purity.”
§2The Buddha saw them plunging in and out.
The heartfelt saying
§3Then, understanding this matter, on that occasion the Buddha expressed this heartfelt sentiment:
§4“Purity doesn’t come from water,
no matter how many people bathe there.
One who has truth and principle,
they are pure, they are brahmins.”
