Death - Ug Krishnamurti

What we call death is nothing but a reshuffling of atoms, and the reshuffling of atoms takes place for the simple reason that the level of energy in this universe has to be maintained. It is for this very reason, that is, to maintain the level of energy, that millions and millions of people have been wiped out through catastrophic
events. For nature it is not catastrophic. An earthquake is as much a necessity, as much a part of the planetary activity, as any other event.
