I highly recommend this video of Dr. Bruce Lipton presenting at the Institute of Noetic Sciences.
As he discusses the groundbreaking new discoveries that have been made regarding the interaction between mind, body, and the processes by which cells receive information, we learn that genes and DNA do not control our biology, but rather, DNA is controlled by signals from outside the cell, including the energetic messages emanating from our thoughts.
In this video, he demonstrates how the new science of Epigenetics is revolutionizing our understanding of the link between mind and matter and the profound effects it has on our personal lives and the collective life of our species.
