All life is a struggle; both without and within there are conditions against which man must contend; his very existence is a series of efforts and accomplishments, and his right to remain among men as a useful unit of humanity depends upon the measure of his capacity for wrestling successfully with the elements of nature without, or with the enemies of virtue and truth within. It is demanded of man that he shall continue to strive after better things, after greater perfection, after higher and still higher achievements; and in accordance with the measure of his obedience to this demand, does the angel of joy wait upon his footsteps and minister unto him; for he who is anxious to learn, eager to know, and who puts forth efforts to accomplish, finds the joy which eternally sings at the heart of the universe. First in little things, then in greater, and then in greater still, must man strive; until at last he is prepared to make the supreme effort, and strive for the accomplishment of Truth, succeeding in which, he will realize the eternal joy.
