The "Whole in every part" is a principle known by poets, mystics, great thinkers, children and ordinary people like you and I, since the beginning of time. It was intelligently presented to the scientific community of the Western world during the second half of the last century by physicist David Bohm, an associate of Albert Einstein and neurophysiologist Karl Pribram.
Can you “see the world in a grain of sand, and heaven in a wild flower, hold infinity in the palm of your hands, and eternity in an hour?” (William Blake).
From Bohm’s perspective, the universe is recognized to be holistically interconnected through resonance occurring within the underlying Unified Field that connects all matter, energy and information in the cosmos. In fact, Bohm and many scientists, mystics and again: regular people like you and I, believe that despite its apparent solidity the universe is a gigantic splendidly detailed, multi-dimensional, super-hologram.
I personally believe that the human brain is an organ to process, reflect and translate the holographic universe. An individual’s brain is like a portal that is connected to the super-hologram of the Grand Universe.
