This is one of the last books written by James Allen. Like all his works it is eminently practical. He never wrote theories, or for the sake of writing, or to add another to his many books; but he wrote when he had a message, and it became a message only when he had lived it out in his own life, and knew that it was good. Thus he wrote facts, which he had proven by practice. To live out the teaching of this book faithfully in every detail of life will lead one to more than happiness and success-even to blessedness, satisfaction and peace. - Summary by Lily L. Allen
