“Astral Projection” by Brad Steiger (1982 edition scan)
"Far more than just a scholarly dissertation on out-of-body experiences, Astral Projection examines the scientific and non-scientific evidence of this amazing occurrence. You'll find everything from controlled laboratory experiments to Steiger's work with color and Peruvian whistling vessels as means of controlling your out-of-body experiences.
Take part in experiments that will tell you about your past life. Maybe you were a peasant, a soldier or even an aristocrat. Discover how these past lives affect the way you are now. Imagine being able to contact long-dead relatives. What could you do with the knowledge they can pass on to you? Learn a variety of techniques that will allow you to project your spirit out of your physical body and find out why those who have mastered astral travel have no fear of death."
