In this work, H. Spencer Lewis leads an investigation and discussion on the cyclical hidden forces which work to alter and affect our lives each day. Notable within the occult movement for his research and accounts of forces unknown, Lewis pioneered a system that explains much of the unusual events that beset both people and the world at large. Namely that a supreme and unending series of cycles permeate the universe, themselves influenced by cosmic forces acting beyond our planet and solar system. These forces span all manner of things; life and death, the creation of souls, and the very passage of time. Each of the phenomena for which the cyclical forces are responsible receive explanation. Lewis was fascinated by this background energy, and would even invent devices intended to detect and measure cosmic rays. This book also acts as a life guide; by observing, predicting and acting according to the cyclical phenomena in our lives, we may enjoy fortune, prosperity and harmony in everyday existence.
