We know the present theories of the Cosmos according to the modern astronomers and physicists, and at the same time we know how wofully they hurt the old school of theologians, and how every new scientific discovery that is made is as a bomb thrown into their house, and how they have attempted in every age to put down all these researches. In the first place, let us go over the psychological and scientific ideas of the Orientals as to cosmology and all that pertains to it, and you will find how wonderfully it is in accordance with all the latest discoveries of modern science, and when there is anything lacking you will find that it is on the side of modern science. We all use the word Nature, and the old Hindu philosophers called it by two different names, _Prakriti_, which is almost the same as the English word “nature,” and by the more scientific name, _Avyaktam_ (“undifferentiated”), from which everything proceeds, out of which come atoms and molecules, matter and force, and mind and intellect. It is startling to find that the philosophers and metaphysicians of India ages ago stated that mind is but matter in a finer form, for what are our present materialists striving to do but to show that mind is as much a product of nature as the body? And so is thought; and we shall find by and by that the intellect also comes from the same nature which is called _avyaktam_, the undifferentiated. The ancient teachers define _avyaktam_ as the “equilibrium of the three forces,” one of which is called _Sattva_, the second _Rajas_ and the third _Tamas_. _Tamas_, the lowest force, is that of attraction, a little higher is _Rajas_, that of repulsion, and the highest is the control of these two, _Sattva_, so that when the two forces, attraction and repulsion, are held in perfect control, or balance, by the _Sattva_, there is no creation, no movement; but as soon as this equilibrium is lost, the balance is disturbed and one of these forces gets stronger than the other. Then change and motion begin and all this evolution goes on. This state of things is going on cyclically, periodically; that is to say, there is a period of disturbance of the balance, when all these forces begin to combine and recombine, and this universe is projected; and there is also a period when everything has a tendency to revert to the primal state of equilibrium, and the time comes when a total absence of all manifestation is reached. Again, after a period, the whole thing is disturbed, projected outward, again it slowly comes out in the form of waves; for all motion in this universe is in the form of waves, successive rise and fall.
