The Buddha (from the Sutta Nipata)

“He who can curb his wrath as soon as it arises, as a timely antidote will check snake’s venom that so quickly spreads — such a monk gives up the here and the beyond, just as a serpent sheds its worn-out skin.”

The Buddha

“Conquer anger with non-anger. Conquer badness with goodness. Conquer meanness with generosity. Conquer dishonesty with truth.”
