Well. I believe that the soul does not start from anywhere, it awakens... In a sense, I remember when I was a baby, I used to have awakenings, and then it was like I was sleeping, whereas when I asked my mom, I apparently was not sleeping at that time. Its like I was on "automatic". For example I remember myself on a hill, surrounded by tall grass, and somewhere down there was a river. And that image is all that I remember. My mom tells me thou that they were looking for me and found me amongst many ants, and that I was looking at them ants, not afraid in any sense. Well I have no recollection of that whatsoever...so what I believe is that the fact that I do not remember myself in this situation does not mean that "I do not remember" that, but rather means that I did not have control over-myself at that time, sort of sleeping soul but awaken body. So in terms of soul, I believe if you were to graph soul as a function over time, the function would be exponential. This function would represent the percent of control the soul has over the body as y-axis over time as x-axis. and you would have the function be an exponential starting from infinity approaching 0, growing to 100% and never approaching it, then decreasing once we get close to death, exponentially decreasing and once again approaching close to 0, but never touching it. And that is my interpretation of soul.
