"To master the contents of these books, is to master the sum of human knowledge in the various departments of science. With this mastery there will come to us the largest understanding, and the clearest obtainable conception of our relations toward each other, and to the universe around us. Thus enlightened, we may discover that ignorance is a sin; that as responsible entities in the great pulsing sea of cosmic life, with more or less power to help or hinder the purpose and perfect unfoldment of all life--we cannot afford to be selfish, sinful or cruel in our actions toward each other, or toward any other form of cosmic life. Having once acquired these convictions, with this most important fund of information, we possess the key which will unlock the mystery of the action and reaction of the potent and unseen forces of nature, which affect us as individuals, as they do the earth, air and water, the elements so necessary to our existence. The restless, never-satisfied, questioning spirit, born with every human soul, is the expression of a divine purpose! To gratify this insatiable desire for more knowledge, is to comply with the demands of a wise cosmic law. By so doing, we enter into the enjoyment of a never-failing source of perpetual delight. We are crowned with a happiness of the purest type! "In viewing this vast field of knowledge, spread so invitingly before us; in anticipating the joy we may glean therefrom; we catch a glimpse of the exceeding richness of the boon of immortality, which, as a spiritual heritage, is waiting for us. We begin slowly to understand ourselves as the repositories of infinite possibilities!--as cosmic units of the larger Cosmos--as a perfect microcosm of the macrocosm! With feelings of awe-inspiring adoration, we reflect that we may know ourselves as individuals, only as the extent of our knowledge of the universe around us is increased. Responding to the law of action and reaction, the more we reflect, the greater becomes our desire to know more of ourselves. Always more! Ever more! Never quite satisfied! Fortunately, the immortality of the wisdom loving human soul embraces all time, and all eternity! Therefore, through the law of eternal progression, we may naturally and rightfully aspire to the acquirement of all possible knowledge. In cultivating these aspirations, we may rest assured that we shall constantly gain new conceptions and new meanings for the word 'Heaven.'
