So astral projection has been a focus in my practices and studies for awhile. Recently, I picked up a book from a local bookstore, and I thought I should share it with you all. Its called Astral Projection for Psychic Empowerment by Carl Llewellyn Weschcke and Joe H. Slate.
The book has a number of useful topics, including various ways and means of using AP for healing and psychic development, but it also helps give an overall understanding as to what one is capable of in the astral realm. The book also features a host of good practices and techniques for strengthening one's energy body for astral travel, and overall techniques for achieving astral projection.
