Religion of God

I had my reservations that all the religions seemed same to me as I paced through my life and read a few books on it - one should be named here "Evolution of God" by Robert Wright - when eventually I was led to a knowledge that perhaps all the religions sprang out from one single divine belief that was once monolith in the whole world but now appendages of it has grown out with branches that spread into subdivisions which we refer to as 'religions'. I won't call it a belief, but a path leading towards better understanding of my belief.
