When we hear the phrase “mind over matter”, we think of it as a spiritual idea, a not a physical reality. This lecture ” the biology of belief” given by Dr Bruce Lipton, a cellular biologist and medical school professor, gives us hard physical science that proves it. The lecture and research put forward, proves how genes do not control biology, cells can live and behave with all genes and DNA removed. It is our perception of our environment and ourselves, that choose the behavioral proteins. Mind over matter is no just a catchphrase, but is a biological truth.
