Chapter III: Sleep And Death
When in his backward journeying man has attained the moment of his birth, all such cravings having now undergone the cleansing fire, there is no longer anything to hinder his unimpaired devotion to the spiritual world. He enters on a new stage of existence. Just as in death the physical body, and soon after it the etheric body was laid aside, so now there falls away and disintegrates the part of the astral body which is unable to live save in the consciousness of the external, physical world. Therefore for supersensible science there are no less than three corpses—physical, etheric and astral. The point of time at which the astral corpse is shed is given by the fact that the period of purification lasts about a third as long as the past life between birth and death. Why this is so will only be clear at a later stage, when the whole course of human life has been more thoroughly gone into in the light of Occult Science. For supersensible perception there are ever present in man's environment the astral corpses cast aside by those who are passing form the stage of purification on to higher levels of existence. It is analogous to what is obviously true for physical perception: physical corpses come into being where human communities are living.
