When a man is stimulated by his own thoughts, full of desire and dwelling on what is attractive, his craving increases even more. He is making the fetter even stronger. But he who takes pleasure in stilling his thoughts, practising the contemplation of what is repulsive, and remaining recollected, now he will make an end of craving, he will snap the bonds of Mara. His aim is accomplished, he is without fear, rid of craving and without stain. He has removed the arrows of changing existence. This is his last body.
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 Buddha
