I would become a Buddhist but it raises more questions than it answers. Theodicy, I am reconciled with - why do Christians believe that God is all good? He is all powerful, yet has a dark heart (theology of Auschwitz). Back to Buddhism. Tibetans hold that the soul wanders, in the Bardo. Others that reincarnation takes place at conception, others at birth, others in between.
Stevenson of West Virginia did a pioneering study but did he prove that reincarnation exists? Cryptonesia, a girl in Finland recites Anglo-Saxon texts. Not reincarnation, but she had read a book a year before and subconsciously recalled it.
