This book's purpose is to furnish a statement of the Spiritual Philosophy of Life with special reference to physical health. We make no claim for the originality of any ideas here expressed. The author has given the substance of these Chapters in lectures, to his classes, and to his patients. They have proved their helpfulness, and people have made many urgent requests to have them put into more permanent and available form. We send these Chapters forth in the hope that they may bring help to a steadily increasing company of people. The purpose is to interpret the truth in the language of modern thought so that these good people may see that every blessing of the good God, both temporal and spiritual, is available right where they are, without forsaking religion for self-appointed vendors of vagaries, and without depriving themselves of the advice of trained physicians, which they often need. Many medical professions are using the agencies of mental and spiritual powers. Their contributions to the advance of sound mental therapeutics are known to anyone who cares to know, although a conservatism has usually marked it, born probably of an instinctive distrust of illogical statement and unreasoning enthusiasm. If we serve these purposes, the author will feel amply repaid for the effort.
