A monk who’s fully ordained shouldn’t intentionally kill a living being, not even a small insect. If he intentionally kills a human being, even causing an abortion, he’s not an ascetic, not a Sakyan monastic. Just as an ordinary stone that has broken in half cannot be put back together again, so too is a monk who has intentionally killed a human being not an ascetic, not a Sakyan monastic. You shouldn’t do this for as long as you live.

A monk who’s fully ordained shouldn’t claim a superhuman quality, not even just saying, ‘I delight in solitude.’ If, because he has bad desires and is overcome by desire, he claims to have a non-existent superhuman quality—whether absorption, release, stillness, attainment, path, or fruit—he’s not an ascetic, not a Sakyan monastic. Just as a palm tree with its crown cut off is incapable of further growth, so too is a monk with bad desires, overcome by desire, who claims to have non-existent superhuman quality not an ascetic, not a Sakyan monastic. You shouldn’t do this for as long as you live.” The four things not to be done are finished.

66. The one ejected for not recognizing an offense At one time a certain monk disrobed after being ejected for not recognizing an offense. He then returned and asked the monks for the full ordination. They told the Buddha.
