Let us recapitulate before going into details. The _Real Man_ is the trinity of _Atma-Buddhi-Manas_, or Spirit and Mind, and he uses certain agents and instruments to get in touch with nature in order to know himself. These instruments and agents are found in the lower Four—or the Quaternary—each principle in which category is of itself an instrument for the particular experience belonging to its own field, the body being the lowest, least important, and most transitory of the whole series. For when we arrive at the body on the way down from the Higher Mind, it can be shown that all of its organs are in themselves senseless and useless when deprived of the man within. Sight, hearing, touch, taste, and smelling do not pertain to the body but to the second unseen physical man, the real organs for the exercise of those powers being in the Astral Body, and those in the physical body being but the mechanical outer instruments for making the coördination between nature and the real organs inside. CHAPTER V. The body, as a mass of flesh, bones, muscles, nerves, brain matter, bile, mucous, blood, and skin is an object of exclusive care for too many people, who make it their god because they have come to identify themselves with it, meaning it only when they say “I.” Left to itself it is devoid of sense, and acts in such a case solely by reflex and automatic action. This we see in sleep, for then the body assumes attitudes and makes motions which the waking man does not permit. It is like mother earth in that it is made up of an infinitesimal number of “lives”. Each of these lives is a sensitive point. Not only are there microbes, bacilli, and bacteria, but these are composed of others, and those others of still more minute lives. These lives are not the cells of the body, but make up the cells, keeping ever within the limits assigned by evolution to the cell. They are forever whirling and moving together throughout the whole body, being in certain apparently void spaces as well as where flesh, membrane, bones, and blood are seen. They extend, too, beyond the actual outer limits of the body to a measurable distance.
