#astral soul

If we study Plato and other philosophers of old, we may readily perceive that while the ʺirrational soul,ʺ by which Plato meant our astral body, or the more ethereal representation of ourselves, can have at best only a more or less prolonged continuity of existence beyond the grave; the divine spirit — wrongly termed soul, by the Church — is immortal by its very essence.
If the life‐principle is something apart from the astral spirit and in no way connected with it, why is it that the intensity of the clairvoyant powers depends so much on the bodily prostration of the subject? The deeper the trance, the less signs of life the body shows, the clearer become the spiritual perceptions, and the more powerful are the soulʹs visions. The soul, disburdened of the bodily senses, shows activity of power in a far greater degree of intensity than it can in a strong, healthy body.
