William Walker 
Dynamic Thought [EPUB ebook] 

From the Foreword: 'This is a queer book. It is a marriage of the Ancient Occult Teachings to the latest and most advanced conceptions of Modern Science—an odd union, for the parties thereto are of entirely different temperaments. The marriage might be expected to result disastrously, were it not for the fact that a connecting link has been found that gives them a bond of common interest.’
