David Bohm may be correct that we will never understand fully the underlying principles. - Just an aside about David Bohm: I consider myself very fortunate, at a place in my life where I was questioning "time" and it's true meaning, to have come across one of David Bohm's books. I hadn't searched anything outside the scriptures and books pertaining to it (because anything outside it was evil and considered taboo) when this book literally fell into my hands. I had already lost faith in the limited knowledge I was allowed to study by my own religious belief. I was starving from lack of knowledge and had grown quite ill. I can say for sure the boundaries of my mind was blown away the day I read it, and I've not seen hide nor hair of those boundaries since! Thank You David Bohm...where ever you are!
