Prana, the portion of the life-energy appropriated by the man in his embodied state, having lost its vehicle, the ethereal double, which, with the physical body, has slipped away from its controlling energy, must pass back into the great life-reservoir of the universe. As water enclosed in a glass vessel and plunged into a tank mingles with the surrounding water if the vessel be broken, so Prana, as the bodies drop from it, mingles again with the Life Universal. It is only "just after death" that man is a quintile, or fivefold in his constitution, for Prana, as a distinctively human principle, cannot remain appropriated when its vehicle disintegrates. The man now is clothed, but with the Kama Rupa, or body of Kama, the desire body, a body of astral matter, often termed "fluidic," so easily does it, during earth-life, take any form impressed upon it from without or moulded from within. The living man is there, the immortal Triad, still clad in the last of its terrestrial garments, in the subtle, sensitive, responsive form which lent it during embodiment the power to feel, to desire, to enjoy, to suffer, in the physical world. When the man dies, his three lower principles leave him for ever; _i.e._, body, life, and the vehicle of the latter, the etheric body, or the double of the living man. And then his four principles--the central or middle principle (the animal soul or Kama Rupa, with what it has assimilated from the lower Manas) and the higher Triad--find themselves in Kamaloka.[20] This desire body undergoes a marked change soon after death. The different densities of the astral matter of which it is composed arrange themselves in a series of shells or envelopes, the densest being outside, shutting the consciousness away from all but very limited contact and expression. The consciousness turns in on itself, if left undisturbed, and prepares itself for the next step onwards, while the desire body gradually disintegrates, shell after shell. Up to the point of this re-arrangement of the matter of the desire body, the post-mortem experience of all is much the same; it is a "dreamy, peaceful semi-consciousness," as before said, and this, in the happiest cases, passes without vivid awakening into the deeper "pre-devachanic unconsciousness" which ends with the blissful wakening in Devachan, for the period of repose that intervenes between two incarnations. But as, at this point, different possibilities arise, let us trace a normal uninterrupted progression in Kamaloka, up to the threshold of Devachan, and then we can return to consider other classes of circumstances.
