Advances in science have opened many wonders to us in quantum physics, medicine and much more, and yet, there is another source of knowledge that gives deep insight, often preceding the knowledge of science. The preface to this book states the following: "This book is meant to stimulate thought in all of mankind and to motivate the individual to live his life earnestly - both in thought and word, as well as in deeds." And so, deep insight is given to us in this book. Regardless of whether it has to do with the effects of thoughts and feelings on the body, or with the effects of disturbances in the Earth's magnetic fields on the human being, or on whether the harmful parasites and other pathogens are created by the conduct of people themselves, all of this and much more, has been confirmed by science, something mankind considered unthinkable three decades ago, when this book was first published.
