Astral Projection is the practice of navigating the hidden worlds beyond the material by leaving the body — "psychic space travel." It is the core method of Astral Spaceways Incorporated, and the same navigation the clergy use to ascend The Cosmic Tree and locate The Calf on the astral plane. Magnetic Rose is its most advanced practitioner; it was during an astral-travel session, on an early level of the tree, that she first met the Herd.
