Dennis Klocek has for many years studied and incorporated Western esotericism into his own inner research, focusing especially on alchemy and the wisdom and practicality of Rudolf Steiner's spiritual science. Based on thirteen lectures, he discusses human physiology and the hidden forces and processes that sustain our life on Earth and beyond. His informal and accessible approach delves deeply into specific organs, functions, life processes and diseases, drawing vivid images for the reader that stimulate a profound understanding and appreciation of human physiology.

The topics discussed include a wide range of diseases, physical and spiritual organs, psychology, sleep and dreams, digestion, emotions, consciousness, aging, a variety of therapies and much more. Dennis Klocek offers a comprehensive owner's manual for our human body.
