Product Description
The hardest three obstacles I encountered while accomplishing this work were the English language, which I do not master enough, studying and experimenting psychological phenomena, hypnosis etc., and attempting to simplify a complex science that embraces biology, physics, psychology, literature, religion and more. To link these various fields of science together, one has to use sane imagination, vast knowledge, and should have the ability to read foreign languages and to carry through long research and hard studies.
