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.'
ShantidevaThe hostile multitudes are vast as spaceWhat chance is there that all should be subdued? Let but this angry mind be overthrownAnd every foe is then and there destroyed
Shantideva
