Mental Therapeutics [EPUB ebook] 

These lessons give you the essence and substance of the best scientific knowledge regarding the prevention and cure of physical ills by the power of the mind.
But in presenting the theory and practice of Mental Therapeutics there is absolutely no reference to mysticism or occultism, or strange metaphysical and philosophical theories. Mental Therapeutics is a science, not a superstition; it is something based on sound scientific facts, and not upon vague imaginings.
