At the ending of a universe, the tattvas merge in each other by disintegration; Prithivî Tattva, having disintegrated into atoms, these atoms are themselves broken up, and the tanmâtra that formed them, being no longer able to express itself for lack of suitable material, ceases to be a power, and remains only represented by a modification in consciousness – a permanent possibility. Thus Apas Tattva becomes the lowest manifestation, and, by a repetition of the above process, ceases to exist. In like fashion each successively vanishes. Hence, Mahâdeva is represented as saying in the Shivâgama: "The universe proceeded from the tattvas; it goes on through the tattvas; it vanishes into the tattvas."
Such is the grandiose conception of the kosmos given by the science of antiquity; one life, pulsing into innumerable vibrations, and these throwing matter into forms. On this was based the Pythagorean system of numbers; on this mathematics and music were founded; on this the "Great Science," or Magic, of long-perished nations was built up. That science only survives in its purity in the Great White Brotherhood, but its traces may yet be seen in the scriptures and the religions of the world.
We take up modern science, and pass into a different atmosphere. Now phenomena are to be studied, forms are to occupy our attention. But as we look at modern science we find that it is beginning to transcend the study of forms; we find the efforts of its greatest men are turned to seek unity amid diversity. Do not think that, in speaking of modern science as studying forms, I am indifferent to the mighty achievements that it has made, or that I would say one word in derogation of the ability of the leading men of science, and the priceless value of the work that they are doing for humanity. Their achievements during the present century are achievements that are worthy of the very deepest respect, not only for the "sublime patience of the investigator," of which William Kingdon Clifford so rightly spoke, but also for the self-abnegation with which many of them have given their lives to follow truth, to study in the innermost recesses of the phenomena of nature what secrets she has hidden, what may be underneath the "Veil of Isis." I do not, then, speak a word against modern science, but I point out to you this fact, that the greatest work of science has been the generalisations that have been suggested in the attempt to reach simplicity, to reduce multiplicity to unity. How far has science gone from that generally accepted view of the materialistic school of thirty years ago, that the universe is made up of an indefinite number of atoms, the atoms being our chemical elements! A phrase from one of the most famous of the then leading men of science, Dr. Ludwig Büchner, will mark the greatness of the change: he declared that the carbon atom will always remain a carbon atom, and has been a carbon atom from all eternity; that the hydrogen atom from all eternity has been a hydrogen atom, and to all eternity a hydrogen atom it will remain; for atoms with their properties are indestructible, and are therefore eternal. What man of science would dare to allege that to-day, knowing that he would be laughed to scorn by all his scientific brethren; who would say that these atoms are eternally of the same nature as they have till now been made out to be? What is science in fact, doing as to the atom? It is finding in what is called the atom a composite body, a compound, not an element. This discovery is chiefly due to the researches of Sir William Crookes, who is guided in his investigations by a deeper philosophy of the universe than is common among scientists. It is gradually finding out that these atoms are things that are built up gradually, and that the qualities of atoms are not fixed, but are properties that change with every difference of conditions. Late investigations have shown that when chemical bodies are submitted to extraordinary conditions of cold – such cold as makes the air into a liquid and solidifies hydrogen and oxygen – they suffer the destruction of their supposedly permanent properties. It is proved that, as these conditions are changed, and as lower and lower ranges of temperature are brought to bear upon these chemical elements, one by one their eternal properties disappear, and they lie there changed in their activities, and lose the characteristic traits which enabled them to be discovered as parts of the moving world. Downward and downward falls the temperature, property after property disappears, until science asks, bewildered, what will happen when we reach the absolute zero, what will then become of the properties of matter, what will remain of the characteristics of the elements? Is there not but one Matter, and are not all chemical elements but modifications, aggregations, of this one ultimate matter? Similarly with Force, modern science has made the magnificent generalisation that all the forces that we know are modifications of one Force, and are identical in their essential nature; that heat, and light, and all the various forces around us, electricity, magnetism and the rest, that all these are but vibrations of varying lengths and activities in a subtle medium, and that they may be transmuted the one into the other. They are not fundamentally different, but are one and the same in their root. But if this be so, if there be but one Matter, if there be but one Force, then science is now tending towards unity; and as that unity is traced or aimed at, science will have to pass out of the grosser realm of dense matter into the realm of forces working in subtle media; and we find this wondrous change that, whereas in old days the existence of force was argued for inductively, by studying the changes in matter, now science is beginning to posit the existence of force and to question whether matter is anything more than the action of force. Instead of regarding an atom as a solid indivisible particle, the tendency is to regard it as a vortex of energy, a centre of force. One writer even goes so far as to suggest that an atom is a source "through which an invisible fluid is pouring into three-dimensional space." Other atoms, "anti-atoms," may be "sinks" through which the fluid pours out. If these unite, may not inertia be neutralised as well as gravity? May there not be potential matter, and may there not be such in space, without any of the attributes which characterise matter, but ready to be vivified and form a system of worlds? Here we have H. P. B.'s atoms and laya centres, put forward tentatively as a scientific problem. Science is mounting into the invisible world and is trying to measure and to weigh that which therein it finds. Now this tendency to unity is the testimony to the One that underlies all manifestation; only one Force, only one Matter; endless diversity of forces, transmutable into each other; endless diversity of forms, which break up again to recombine; only one Force under all forces, one Matter under all forms. It is seen that the very fact of harmony and of evolution points to a root unity, and that eternally independent self-moving particles would only perpetuate a chaos.
As science travels along this most hopeful line, we find great changes are arising in the nature of the studies that are being carried on, and we have that wonderful theory of Sir William Crookes of the genesis of the elements. He takes protyle as a starting-point, which is really Vâyu in its form on this physical plane – Prithivî Vâyu – and out of that builds one atom after another, making all the chemical elements to be bodies aggregated together by the action of a positive and a negative force. Let me just remind you of this, because some amongst you go so eagerly after modern science and despise your own literature. If you had read your Vishnu Purâna, with your brain, and not merely with your eyes through modern spectacles, you might have learnt that theory of Sir William Crookes long, long before he gave it. He has drawn a picture, and the picture shows an immovable axis, and around it a spiral coil, and at points in that coil are atoms of the chemical elements, generated by that coil which represents a swinging and cooling force. That spiral is in the great ocean of protyle, or primeval matter, and, as that spiral goes round and round the immovable axis, it generates chemical elements one after another, and so brings into existence the materials out of which the world is to be formed. That is the dry scientific statement summarised from his own address. But I have read in an ancient
