I am sitting here, and it has suddenly dawned on me that I don't know how much of my personality is a product of my genetic makeup and how much is from an aggregation of my past lives. Is it possible to change from lifetime to lifetime simply because of a different genetic makeup? ( I know, for example, that when I was female, which in most instances I was female in my past lives, I had a very different personality in each instance) So in each lifetime, we are either somewhat different or radically different depending on the influence of genetics, yet somehow we retain our former idenity as formed in our past lives. So this leads to the question; which is stronger in the the makeup of our personality? Our genetic structure, or our soul signature which was passed along in a long succession of past lives?
