The dependence of man and the independence of man depend upon what he wishes to experience. If he wishes to experience the dense earth, he depends upon the dense body; if he wishes to live the life of the spirit, he need not depend upon anything. The spirit is living, the spirit is life itself; it only depends upon matter for its experience and not for its life; for the spirit itself is life, though a life which is different from the life we generally recognize as such. What we call living is the matter which has absorbed spirit; and what we call life is that which is moving, acting through and by that spirit. In reality life is that which matter has absorbed; life passes away from matter and remains; life cannot be destroyed. It is in the understanding of this that lies the secret of immortality.
