Heart Lectures, by Ehrenfried PfeifferMercury Press
What is the greater significance of the heart? Pfeiffer sees it and explains it as an etheric organ, an inner sun. He describes how its motion reflects the expansion and contraction of the cosmos itself and asserts that it doesn't "pump" blood as we normally think, but etherizes it. Included is a description of the manifestations of different mystery streams in ancient cultures.
