Einstein had a lot of respect for Spinoza's "pantheism", as do I. "Pan"=all, "theos"=God. God is everything, everything is God. If the world insists that we align our belief system around the word "theos", then pantheism is way better than atheism, but it doesn't reduce reality to a mere mechanism. It leaves room for an abstract side of reality that we might label "divine", without resorting to anthropomorphism.
Einstein is also interesting because he wrote the foreword to Upton Sinclair's classic work on ESP, "Mental Radio." He is far less dismissive of Sinclair's research than the typical atheist. I read the foreword here: [www.youtube.com]
By the way, there's no need to purchase my ten-year-old non-fiction book "Reality Check". It was written only a year after my paradigm shift into esoteric spirituality, and it was essentially an early prototype for what became "I, Universe" - over twice as big, and packed with a decade of research and experience.
