All the suffering in the world comes from seeking pleasure for oneself. All the happiness in the world comes from seeking pleasure for others.
ShantidevaPassion is overcome only by him who has won through stillness of spirit the perfect vision; it comes through the contentment that is regardless of the world.
ShantidevaAs long as space abides and as long as the world abides, so long may I abide, destroying the sufferings of the world.
Shantideva
