Are you a mental slave, your mind the servant of outside forces? Would you rather be a mental master, your thoughts taking charge not only of mind and body, but destiny? Theron Q. Dumont, a pioneer of the early 20th century's New Thought movement, here gives practical, step-by-step instruction on mastering control of not only the conscious mind but, more importantly, ‘those marvelous faculties which operate on the subconscious planes.’

In this book there will be nothing said concerning metaphysical theories or philosophical hypotheses; instead, there will be a very strict adherence to the principles of psychology. There will be nothing said of 'spirit' or ‘soul’; but very much said of ‘mind’. We know much about how the mind works, but we know little or nothing about what the mind really is. But, for that matter, so far as practical purposes are concerned, it makes very little difference to us just what the mind is, providing we know just how it works, and how it may be controlled and managed.
