Evil-doers who denounce the wise resemble a person who spits against the sky; the spittle will never reach the sky, but comes down on himself. Evil-doers again resemble a man who stirs the dust against the wind; the dust is never raised without doing him injury. Thus, the wise will never be hurt, but the curse is sure to destroy the evil-doers themselves.
Gautama BuddhaJust as a mother would protect with her life her own son, her only son, so one should cultivate an unbounded mind towards all beings, and loving-kindness towards all the world. One should cultivate an unbounded mind, above and below and across, without obstruction, without enmity, without rivalry. Standing, or going, or seated, or lying down, as long as one is free from drowsiness, one should practice this mindfulness. This, they say, is the holy state here.
Gautama BuddhaYou yourself must make an effort. Buddhas are only show the way. The thoughtful who enter the way are freed from the bondage of defilements.
Gautama Buddha
