Henry Thomas Hamblin's The Power of Thought stands between that of James Allen's As a Man Thinketh, and A Course in Miracles. It appeals to those seeking to improve their lives, whether by the practical application of thought or through following a more spiritual path. "By thought man either blesses or curses himself. By it he brings into his life either success or failure, health or disease, happiness or unhappiness, poverty or prosperity. It is all in his mind and the character of his thought. Whatever there is in your life or mine, of disharmony, lack, sickness or unhappiness, is the result of our disharmonious thought. We live in an orderly Universe, but we do not react harmoniously to our environment, we are not in correspondence with the hidden law and order around us. It is not necessary for the universe to be altered; what is needed is that we ourselves should be changed. Within ourselves is the cause of the disorder in our own individual world-for we each live in a little world of our own creation- therefore, the disorder and trouble lhal afflicts us, or the lack that restricts our life, can never be overcome, save by a change of mind, habit of thought, and mental attitude." Henry Thomas Hamblin was an English mystic and New Thought author. He believed that "abounding health, sufficiency of supply, achievement, accomplishment and joy indescribable are the normal state for man.", and that, to achieve this state, man needed to come into "harmony with Cosmic Law".
