“No One Can Purify Another” (Dhammapada 165)
This verse hands you both a burden and a freedom: you are the one responsible for your own heart. Wrongdoing and the defilement it brings, the refraining and the purity that follows — all of it, the Buddha says, is your own doing. “No one can purify another.” Here is the verse, what it means, and where it comes from.
“By oneself is evil done; by oneself is one defiled. By oneself is evil left undone; by oneself is one made pure. Purity and impurity depend on oneself; no one can purify another.” — The Buddha, Dhammapada 165 (trans. Acharya Buddharakkhita)
What it means
The verse is built as a tight mirror: evil is done by oneself; it is left undone by oneself; one is defiled and one is made pure by oneself. The repetition is the message — it keeps returning agency to you.
This is at once sobering and liberating. Sobering, because it removes our favourite excuses: my upbringing, my circumstances, the people who wronged me. Those shape conditions, but the moral quality of this response is still mine to own. And liberating, because if purity depends on oneself, then it is also within reach of oneself — no gatekeeper stands between you and the work of cleaning your own mind.
The final clause, “no one can purify another,” is not a denial of help. It is a precise statement of its limit. Others can teach, encourage, and walk beside you; what none of them can do is reach into your mind and do the purifying for you. That part is, irreducibly, your own.
Where it comes from
The verse is Dhammapada 165, from the Attavagga — the chapter “on the Self” — in the Pali Canon, in Acharya Buddharakkhita’s translation.
Why it matters
This is one of the clearest statements of Buddhism’s stress on self-effort. It sits at the heart of why the tradition reads less like a rescue and more like a training: the Buddha is, in his own famous image, one who only points the way. It shapes how Buddhism understands karma — purity and impurity following from one’s own intentions and acts — and it is one reason the question of whether Buddhism is a religion or a philosophy is genuinely hard to answer.

Frequently asked questions
What does Dhammapada 165 teach?
Moral self-responsibility. The verse says that wrongdoing and its defilement, and the refraining from it and the purity that follows, are alike one's own doing. It concludes with the striking line, 'no one can purify another.' Each person is the agent of their own moral state — no one else can do that inner work for you.
Does this mean Buddhism has no place for teachers or help?
No — teachers, friends, and community matter enormously; the Buddha himself taught for forty-five years. But the verse draws a line: others can show the way, encourage, and support, yet they cannot walk it for you. A teacher can point at the path; the actual purifying of your own mind is something only you can undertake.
How is this different from being saved by a god?
It is one of the clearest expressions of Buddhism's emphasis on self-effort. Where some traditions locate purification in the grace of a savior, this verse places it squarely in one's own hands: 'by oneself is one made pure.' Liberation is not granted from outside; it is realised through one's own practice.
