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.'
Shantideva
