A monk, while cutting down a tree with an axe to make a dwelling for himself, accidentally severed the arm of a tree deity’s child. She grew angry and wanted to kill him, but she controlled her anger, reflecting that she would be reborn in hell if she killed a virtuous man, and that other deities would also kill monks in future following her bad example. Instead, she reported the matter to the Buddha, who praised her self-restraint and uttered the verse, “Whoever checks his uprisen anger as though it were a rolling chariot, I call a true charioteer. Others merely hold the reins”. At the conclusion of the verse, the deity was established in Stream-winning. The Buddha pointed out an empty tree at Jetavana near his Perfumed Chamber, and she took up residence there. This occasion was the reason for the laying down of the rule for monks regarding damaging plants.
