INTRODUCTION You are the architect of your own life: it is yours to make or to mar. By the power of thoughts you are building; are you building aright? The power of thought, as Emerson says, is a spiritual power. It is the greatest power that man has at his disposal. The world today is in its present state simply as a result of mankind's collective thinking; each nation is in its present state of either peace and prosperity, or poverty, murder and anarchy, simply as a result of its thinking as a nation; and each individual is what he is, and his life is what it is, and his circumstances are what they are, simply as results of his thoughts. What a man thinks, he becomes; what a man thinks is the mainspring of all his actions; what a man thinks attracts to him his circumstances and environment; what a man thinks determines what type of friends and companions will gather around him; what a man thinks decides whether he shall be happy or miserable, successful or unsuccessful, healthy or unhealthy, prosperous or povertystricken, hated or loved. What a man thinks either builds up his character or pulls it down. What a man thinks can overcome fate or strengthen it, can bring him into alignment with his glorious destiny, or make him an outcast and a wanderer in desert places. Indeed, there is no limit to the power of thought, because it is a spiritual power of intense potency. It is the power which distinguishes man from the brute, it is the power by which he can mount up to God, it is the power which can make the unsuccessful successful in the battle of life, it is the power which can make the loftiest achievement possible, it is the power by which difficulties can be overcome, disadvantages of birth and parentage surmounted, and the life beautified and inspired and energised with Godgiven powers. 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
