Is heaven a place or is it not? Theosophy teaches, as may be found in all sacred books, that after death the soul reaps a rest. This is from its own nature. It is a thinker, and cannot during life fulfil and carry out all, nor even a small part of the myriads of thoughts entertained. Hence when at death it casts off the body and the astral body and is released from the passions and desires, its natural forces have immediate sway and it thinks its thoughts out on the soul plane, clothed in a finer body suitable to that existence
This is called Devachan. It is the very state that has brought about the descriptions of heaven common to all religions, but this doctrine is very clearly put in the Buddhist and Hindu religions. It is a time of rest, because the physical body being absent the consciousness is not in the completer touch with nature which is possible on the material plane.
But it is a real experience and no more illusionary than earth life, it is where the essence of the thoughts of life that were as high as character permitted, expands and is garnered by the soul and mind. When the force of these thoughts is fully exhausted the soul is drawn back once more to earth, to that environment which is sufficiently like unto itself to give it the proper further evolution This alternation from state to state goes on until the being rises from repeated experiences above ignorance, and realizes in itself the actual unity of all spiritual beings. Then it passes on to higher and greater steps on the evolutionary road.
