"Let the dead bury the dead."

"Let the dead bury the dead." is sometimes attributed to a certain higher being's "point of view", suggesting that the walking-dead should be the ones to bury the actually-dead, and that the presumed really alive have no need of either. There are other more metaphorical meanings possible of course, but let's just stay with the obvious one.

In fact, it's an ordinary person's point-of-view regarding the dead. When the dying - and this often includes higher mammals - recognize somehow they are near death, they will very often leave camp, to go somewhere alone to die. After a few days at most, nature has taken care of the remains, and for all intents and purposes, they are buried, superficially perhaps, but scarcely to be seen at all. That is, the dead bury themselves.

Let's dig a little deeper. Thoughts give the impression of being alive as long as they are running rampant in you. When they are effectively, "out of mind", they are also, quite forgotten. Remember them yet again, and you effectively raise them from the dead, to live again - to pretend to be you again. If you could forget large tracts of land housing even larger groups of unwanted, useless members of your chaotic little society of mind (euphemistically called, the 'slumber room', popular in the funeral business), perhaps they would eventually just die off, never to trouble you again. If the dying are not brought back to mystical health by you remembering them, they will soon enough die off completely, and instantly be buried.

The dead bury themselves, in a sane world,
the second they open their mouths critizing it, in any way.

Only the living remain, in a sane world.
