When anger surges, they drive it out,
as with medicine a snake’s spreading venom.
Such a mendicant sheds the near shore and the far,
as a serpent its old worn-out skin.
NOTE: This verse clearly indicates that the Buddha wanted us to remove anger (and all unwholesome states of mind) and not just observe them.
