Looked at the previous link and apparently your considering the value of past life regression hypnotic therapy to prove reincarnation. I took up hypnotism for a while as a lark and can tell you the mind is very susceptible to input and misinterpretation of historical events similar to the dream state (both require the alpha brain wave).
Reincarnation has interested me in the past:
The intellectual wall I encountered was how the population of intelligent life forms in existence increases its population.
I considered that perhaps a frog soul becomes a human soul through successively successful reincarnations but what can a frog learn from a frogs experience and how does that lead to intelligence.
Not trying to be a dick here, just don’t know how you overcame this wall.
P.S. Thanks for the how to quote tip, tried it and liked it.
