Reincarnation

Reincarnation: the ability of the soul to outlive the body, either get lost on the Earth plane or move to a heaven of choice after death and then be reborn to complete a learning cycle back on Earth again.
Two separate authors, one with the post-life spiritual and one with no it's a one-off situation so make the most of it.
The book gives the credentials of the two one a University of Adelaide parapsychology tested Esper and the other someone who calls himself a shaman who's travelled the spiritual path for some 50+ years and used, tested and been acknowledged by people in those spheres of religion and philosophy.
The two different viewpoints are here to make your own minds up as to which you'll believe.
