"O procrastinating one, who thinketh not of the coming of death,
Devoting thyself to the useless doings of this life,
Improvident art thou in dissipating thy great opportunity;
Mistaken, indeed, will thy purpose be now
if thou returnest emptyhanded from this life...
Wilt thou not be acting even as a traitor to thyself?'
The Tibetan Book of the Dead
