I think it is expressed in several religions. I highly recommend the book "The Anatomy of the Spirit" by Caroline Myss.
I'll have to check out this book. Thanks Victor. I think a lot of religions kind of have a similar idea, but I don't think they really embody this particular belief. (perhaps I'm mistaken), but my belief is quite specific about not allowing for saints, messiahs, prophets, ceremonies, sacred books, etc. And, I don't think God is separate from anything. And I think God is still evolving and that it's our responsibility to make that happen. Does that help any? lots of love Anne
