I have recently become more interested in the idea of the lifestream and I have been doing a little bit of work in this area, it nearly drove me to insanity, but ill share my findings. I would recommend you watch "The Secret" and Bill Hicks
Now I believe that the most logical idea of where we came from would be from the meteor that hit the earth and killed the dinosaurs, kinda like the cetra. After the dinosaurs were wiped out we suddenly appeared, so im thinking there was something inside that meteor that created us as we know it now, or influenced earths lifestream if we can call it that (Thats what I think anyway, I could be wrong).
Sp if you watch
"The Secret" you will find out that we are living in a world where everything that in the universe is energy. So im going to put a few quotes from the film in here
"So and we can ask the question what creates the world around us he or she will say energy, well describe energy; it can never be created or destroyed, it always was and always has been, it is everything that ever existed it always exists, and its moving into form, through form and out of form.
So you can go to a theologian and say what created the universe and he or she will say god, ok describe god; always was and always has been, never be created or destroyed, it always was and always has been, it is everything that ever existed it always exists, and its moving into form, through form and out of form.
Its the same description just different terminology
So who are we? We are spritual beings, we are an energy field operating in a larger energy field."
So this kinda fits in with
bugenhagens version of events. So we are all blessed with this spirit energy when we are brought into the world, an energy that always was and always has been.
Now if you want Bill Hicks
version of events: "“Today a young man on acid realized that all matter is merely energy condensed to a slow vibration, that we are all one consciousness experiencing itself subjectively, there is no such thing as death, life is only a dream, and we are the imagination of ourselves."
So the lifestream to me seems as logical as you can put it.
