According to the Talmud, "Sleep is one sixtieth of death."

If sleep is a form of death, then it is also true that death is a form of sleep.

Sleep is not a termination or even an interruption of life. Rather, it is a time of foment, the means by which body and soul recoup their energies for a fresh and refreshed onslaught upon the coming day. So is death. Death is a "descent for the sake of ascent," a retraction of the arrow of life so that it can be impelled by the bow of vacuity with redoubled force.
