The first thing to be known about death is that death is a lie. Death exists not; it is one of the most illusory things. Death is the shadow of another lie -- the name of that other lie is the ego. Death is the shadow of the ego. Because the ego is, death appears to be there.
The secret of knowing death, of understanding death, is not in death itself. You will have to go deeper into the existence of the ego. You will have to look, watch, observe, be aware of what this ego is. And the day you have found that there is no ego, that there has never been -- it appeared only because you were not aware, it appeared only because you were keeping your own existence in darkness -- the day it is understood that the ego is a creation of an unconscious mind, the ego disappears and simultaneously death disappears.
The real you is eternal. Life is neither born nor dies. The ocean continues, waves come and go -- but what are waves? Just forms, the wind playing with the ocean. Waves have no substantial existence. So are we, waves, playthings.
