All life from a single cell to galaxies is subject to the re-birth cycles. The system facilitates personal growth both on the physical and psychological levels. Think of it as a phase change, something akin to water vaporization. Every living being has a physical body bonded to a "soul or astral body". Think of it as the computer's hard drive and memory disk. The physical body being the hard drive, the soul the memory disk. At death the bond breaks, releasing the astral body with all its recorded information, which in subsequent lives can be accessed. This book teaches the method how. Telepathy is the key word. It is the universal means of communication, everybody has it on the conscious or subconscious level. This is how the fetus in the womb communicates with his mother, this is how God communicates.
