Throughout this book we will be seeking answers to many questions about the heart from the ancient Hindu Vedas to cutting edge modern research on heart rate variability. Many misconceptions will be outlined in a timeline that reflects the evolution of heart knowledge over the course of history. One of those gross errors in understanding the heart and its function is the myth that the heart is a pump. The true view of blood circulation is much more complicated and has only become accepted by cardiologists in recent times. Dr. Rudolf Steiner's teachings contend that: "The heart is not a pump; the heart is an organ of perception." As a matter of fact, he believes that the heart is the most important organ of perception that can be trained to become a supersensible organ of perception of both the outside world and the inside world of the human being. The heart is an organ that can commune with the divine through a language of the spirit that is unique to the heart.
