Itzhak Bentov, a Czech born inventor and mystic was very interesting person. He tried to connect spirituality and physics or in other words tried to explain spiritual planes with tools of science. I have seen an interview with Bentov (not available on Google Video anymore), he was very nice and humble man.

What is important, Bentov never said his ideas are complete and ultimate truth. He said these ideas were only a model which needs to be verified and expanded. I highly recommend his books (Stalking the Wild Pendulum and A Brief Tour of Higher Consciousness), they cover a lot of interesting topics on spirituality. Quite simple diagrams and his drawings regarding evolution, consciousness, universe, kundalini energy and meditation are easy to understand for everybody.

Bentov’s ideas (taken from Wikipedia):

• Our bodies are mirrors of the whole universe, at every level.
• Vibration permeates all things.
• The universe and all matter is made of consciousness in the process of developing to higher levels.
• Our brains are thought receivers and amplifiers, not the source of thought.
• All knowledge that has ever been generated is potentially available to us from other consciousnesses somewhere in the universe.
• The universe is a hologram. The brain is a hologram interpreting a holographic universe.
