Notwithstanding the immense amount of attention which has been directed in a broad general way to mind and its action, and although the constructive and creative ability of mind through thinking has been so long and so universally acknowledged, yet we are just now beginning to recognize the close and direct personal relation which thinking bears to man. The limits of the power of mind have never been clearly perceived, but recognition of their extent continually enlarges as knowledge and understanding increase. The differences between ignorant and enlightened, between savage and civilized, between brute and man, are all due to mind and its action. All the multifarious customs and habits of mankind, whether simple or complex, though often attributed to other causes, are, from first to last, the direct results of thinking. The unwritten history of the evolution of clothing, from its rude beginnings in the far-distant and forgotten past through all the ages since man first inhabited the earth, though at first glance seemingly simple, yet, as a whole, is wonderfully complex and astonishing in its particulars. Its story is only the story of the application of mind to the solution of a single one of the vast multitude of problems connected with human requirements. It is true that our factories and palaces, our temples and our homes, are built of earthly material, but mind directed their fashioning into the vast multitude of forms, more or less beautiful, so lavishly displayed by architecture in city and country. The multitudinous products of constructive art which are scattered in lavish profusion over the whole earth are marvelous exhibitions of what mind has done; and these are being multiplied daily. Only in these more recent years has it been clearly perceived that mind action is first in the order of occurrence, and that it is the absolute ruler of man himself as well as of all these wonderful works which mind has created. Mind is the motor power and governs everything, everywhere; but man can control mind, and therefore, by that control, he may be the imperious dictator of his mind's entire course, and, rising thence to the highest pinnacle of possibility, he may become the arbiter of destiny itself.
