see, then after a while hear, and then feel, and while we heard a man talking we should not see him at all, because all the centres are different. This body is made of particles which we call matter, and it is dull and insentient. So is what is called the fine body. The fine body, according to the _Sânkhyas_ is a little body, made of very fine particles, so fine that no microscope can see them. What is the use of it? It is the receptacle of what we call mind. Just as this gross body is the receptacle of the grosser forces, so the fine body is the receptacle of the finer forces, that which we call thought, in its various modifications. First is the body, which is gross matter, with gross force. Force cannot exist without matter. It can only manifest itself through matter, so the grosser forces work through the body and those very forces become finer; the very force which is working in a gross form works in a fine form and becomes thought. There is no real difference between them, simply one is the gross and the other the fine manifestation of the same thing. Neither is there any difference in substance between the fine body and the gross body. The fine body is also material, only very fine material. Whence do all these forces come? According to the Vedânta philosophy there are two things in Nature, one of which they call _Âkâsa_, which is substance, or matter, infinitely fine, and the other they call _Prâna_. Whatever you see, or feel, or hear, as air or earth, or anything, is material. And everything is a form of this _âkâsa_. It becomes finer and finer, or grosser and grosser, and it changes under the action of _Prâna_ (universal Energy). Like _âkâsa_, _prâna_ is omnipresent, interpenetrating everything. _Âkâsa_ is like the water, and everything else in the universe like blocks of ice, made out of that water and floating in it, and _prâna_ is the power that changes the _âkâsa_ into all these various forms. This body is the instrument made out of _âkâsa_ for the manifestation of _prâna_ in gross forms, as muscular motion, or walking, sitting, talking, and so on. The fine body also is made of _âkâsa_, a much finer form of _âkâsa_, for the manifestation of the same _prâna_ in the finer form of thought. So, first there is this gross body, beyond that is the fine body, and beyond that is the _jiva_ (soul), the real man. Just as these finger nails can be pared off a hundred times a year, and yet are still a part of our bodies, not different, so we have not two bodies. It is not that man has a fine and also a gross body; it is the one body, only it remains longer when it is a fine body, and the grosser it is the sooner it dissolves. Just as I can cut this nail a hundred times a year, so millions of times I can shed this body in one æon, but the fine body will remain. According to the dualists this _jiva_, or the real man, is very fine, minute.
