The theme of the book is that the world of the spirit is real and can be learned, to some extent at least. And that spiritual kinowledge based on fact is truly power, and it brings satisfaction and contentment beyond all else to those who seek it. It is about the teaching of "The Ancient Wisdom." Jesus came to teach this as did others before him and others after. There is nothing new about the basic facts. What is new is the more effective way that it can be explained in this modern era. There is no plot---just 50 essays, most of them based on spiritual experiences of the author, each one illustrating some aspect of the world of the spirit. Simple enough for the beginner to get started, yet deep enough to interest for a lifetime. Some aspects are approached from more than one perspective for clarity, inluding metaphysics and a New Testament outlook with remarkable conclusions. Not totally a how-to book, rather a way to select appropriate how-to books. Crammed with valuable insights, it can be a captivating guide for anyone seeking the ancient eternal wisdom. The author, a mechanical engineer, began a spiritual quest at age 37. Adept in the world of science and machines, he was an unlikely personality type to get very far in this type of endeavor. But it soon became apparent to him that there is no real conflict between proven science and true religion. Although this realization is contrary to some long-held popular beliefs, it simplified his religious studies immensely. He met some qualified teachers who knew that the great religious truths are meant for 'here and now' in this lifetime as well as any afterlife, and could teach it well. The eternal wisdom (some of it anyway) 'came through' even to the literal scientific mind of the engineer. And (some of it anyway) can be passed on to the reader.
