One should do nothing other than what is directly or indirectly of benefit to living beings.
ShantidevaDeath will be so quick to swoop on you; Gather merit till that moment comes! Wait till then to banish laziness? Then there'll be no time, what will you do? "This I have not done. And this I'm only starting. And this - I'm only halfway through ..." Then is the sudden coming of the Lord of Death, And oh, the thought 'Alas, I'm finished.'
ShantidevaAll the suffering in the world comes from seeking pleasure for oneself. All the happiness in the world comes from seeking pleasure for others.
Shantideva
