The teaching in one sentence
Simply leaving the household life does not make someone righteous — if a “beast and a bully” goes forth without real ethical commitment, their life only gets worse, and the community they join has both the right and the responsibility to expel them, so the pure can dwell with the pure.
The supreme treasure
The sutta opens with a claim that sounds almost like praise for renunciation itself: “a righteous life, a spiritual life, they call this the supreme treasure.” But the sentence immediately turns into a conditional: “but if someone goes forth from the lay life to homelessness who is of scurrilous character, a beast and a bully, their life gets worse, as poison grows inside them.” The opening compliment sets up its own reversal — the robe alone does not confer the treasure it’s supposed to represent.
What goes wrong
The next several verses describe the failure in specific terms. Such a mendicant “loves to quarrel,” is “wrapped in delusion,” and “doesn’t even know what’s been explained in the Dhamma taught by the Buddha.” Worse, they end up “harassing those who are evolved” — that is, causing trouble for the very practitioners who are actually progressing — “governed by ignorance,” unaware that this corruption “is the path that leads to hell.” The consequence described is stark: “entering the underworld, passing from womb to womb, from darkness to darkness,” such a person “falls into suffering after death.”
The sewer simile
The sutta’s single most unsparing image arrives next: “one such as that is like a sewer, brimful with years of filth, for it’s hard to clean one full of grime.” There is no softening here — the comparison is deliberately physical and unpleasant, chosen precisely because the ordinary language of ethical failure might not land with sufficient force. The verse is not describing an occasional lapse; it is describing something accumulated over years, and correspondingly difficult to reverse.
A call to purify the community
What follows is unusual for the Sutta Nipāta: a direct procedural instruction. “Mendicants, knowing that someone is like this” — attached to domestic concerns, of corrupt wishes and wicked intent, of bad behavior — “then having gathered in harmony, you should expel them.” The imperative continues in blunt, almost domestic language: “throw out the trash! Get rid of the rubbish! And sweep away the scraps — they’re not ascetics, they just think they are.” That last clause is worth pausing on: the sutta does not say these people have failed to become ascetics; it says they mistakenly believe they already are one, a self-deception the text treats as part of the problem.
The positive vision
Only once this instruction is given does the sutta close on a constructive note. Having “thrown out those of corrupt wishes,” the remaining community should “dwell in communion, ever mindful, the pure with the pure.” The final line makes the purpose explicit: “then in harmony, alert, you’ll make an end of suffering.” The expulsion described earlier is not framed as punishment for its own sake, but as a precondition for the kind of mutual practice that actually leads somewhere — a community, like an individual mind, needs to be free of what is corrupting it before it can function as intended.
