sendy47,
I've "always" considered reincarnation as a "fact of life =)". It is the basis of my personal core belief system. My unyielding faith in it's truth has been supported and reinforced by teachings associated with the Unity Church of Christianity, Rosicrucian Philosophy and Western Wisdom Teachings of Christianity.
There are myriad first hand accounts and research proving (to a believer at least) the varacity of it's growing acceptance. One such source (though still unprovable, does prove interesting) can be found at "Past Life Forums".
As contriversial, and at times flammable, a subject as it can be, I find no other explanation suitably explaining the underlying, otherwise unexplainable, variety and complexity of human interaction/behavior. By means of reincarnation, there is always a very real reason for what we do and why.
See my book; "The High Watch, a View of God's Unfolding Divine Plan" on my blog of the same name:
