"Thou grievest for those whom thou shouldst not grieve for, and yet thou speakest words about wisdom. Wise men do not grieve for the dead or for the living. Never was there a time when I was not, nor thou, nor these lords of men, nor will there ever be a time hereafter when we shall all cease to be."
-Krisna talks to Arjuna, Bhagavad Gita
