An introduction to the practical steps toward awakening in the internal planes, or in other words, Astral Travel.

"All human beings travel in the Astral Body during their hours of sleep.  Their dreams are astral experiences; we must learn to remember our astral experiences.  Thus when awakening from our normal sleep, we will practice a retrospective exercise in order to remember all those things that we did during normal sleep." - Samael Aun Weor
