In The Amazing Secrets of the Yogi I have embodied many valuable secrets, which have been collected with great care from the treasured wisdom of Ancient India. “These secrets if put into daily practice will bring you added health, greater success and unbounded happiness. They will prove to be a “guide, philosopher and friend” and will serve you well in times of trouble, difficulty or disease. In fact you will soon come to regard them as the greatest boon that has ever come into your life.” Charles Francis Haanel was an American New Thought author and a businessman. He is best known for his contributions to the New Thought Movement through his book The Master Key System.
