Dhamma Verses (Dhammapada, KN 2)

17: The Chapter about Anger – 207
One should rein in anger
Against the pleas of a tree spirit a monk cut down a tree
thereby injuring her child at the same time; the tree spirit at
first thought to kill him, but restrained her anger and reported
the matter to the Buddha instead, who spoke this verse and
gave her a new tree to live in, and laid down a rule that monks
should not injure trees and plants.
222. Yo ve uppatitaṁ kodhaṁ rathaṁ bhantaṁ va dhāraye,
tam-ahaṁ sārathiṁ brūmi rasmiggāho itaro jano.
Whoever should hold back anger
just like a swerving chariot,
that one is a charioteer,
other people just rein-holders.
