As I had responded back then (using more words than now), I don't believe that birth is separation from the All. It seems like that because we believe we are the body, and we think of ourselves as something separated. In other words, we feel separated because we believe so, remaining to what the eyes see.

The journey is -among other things- about realizing that we continue to be One with the All even while we are in a body... That there is continuation, e.tc
