In a deep metaphysical sense, all that is conditioned is illusory. All phenomena are literally 'appearances,' the outer masks in which the One Reality shows itself forth in our changing universe. The more 'material' and solid the appearance, the further is it from reality, and therefore the more illusory it is.
At the solemn moment of death, every man, even when death is sudden, sees the whole of his past life marshalled before him, in its minutest details. For one short instant the personal becomes one with the individual and all-knowing ego. But this instant is enough to show to him the whole chain of causes which have been at work during his life.
Death consists, indeed, in a repeated process of unrobing, or unsheathing. The immortal part of man shakes off from itself, one after the other, its outer casings, and - as the snake from its skin, the butterfly from its chrysalis - emerges from one after another, passing into a higher state of consciousness.
The human body is constantly undergoing a process of decay and of reconstruction. First builded into the astral form in the womb of the mother, it is built up continually by the insetting of fresh materials. With every moment tiny molecules are passing away from it; with every moment tiny molecules are streaming into it.
