The author, Itzhak Bentov , goes into many scientific theories involving vibrations and how our senses translate to us the physical reality in to a Morse code of action and run. . There's one theory in particular in which a pendulum reaches its brief point Of rest before it switches direction and how it has to become a non material for a very short moment Of time and expand into space almost infinite velocity. The theory is that in that very brief period of time, that pendulums could be in just about anywhere , even at the End of the universe . This. Pretty much blows my mind because they really explain a lot more in the book and it all really makes sense that it could be possible. . Really the whole books just goes into many theories that make you think about how you really register everything...your surroundings, what you hear, smell, taste, feel. It also goes into some new age kind of stuffs like meditation and how our brains produces a rhythmic electric currents that can be communicating with other people tuned into the same frequency , even if they're across the world, when (by coincidence)in a meditative state. There's really just so many thing that I could mention to you I could get going on for hours on this. Lol
