All phenomenal existence resolves itself into force, into a movement of energy that assumes more or less material, more or less gross or subtle forms for self presentation to its own experience. In the ancient images by which human thought attempted to make this origin and law of being intelligible and real to itself, this infinite existence of Force was figured as a sea, initially at rest and therefore free from forms, but the first disturbance, the first initiation of movement necessitates the creation of forms and is the seed of a universe.
Matter is the presentation of force which is most easily intelligible to our intelligence, moulded as it is by contacts in Matter to which a mind involved in material brain gives the response. The elementary state of material Force is, in the view of the old Indian physicists, a condition of pure material extension in Space of which the peculiar property is vibration typified to us by the phenomenon of sound. But vibration in this state of ether is not sufficient to create forms.
There must first be some obstruction in the flow of the force ocean, some contraction and expansion, some interplay of vibrations, some impinging of force upon force so as to create a beginning of fixed relations and mutual effects. material force modifying its first ethereal status assumes a second, called in the old language the aerial, of which the special property is contact between force and force, contact that is the basis of all material relations. Still we have not as yet real forms but only varying forces. A sustaining principle is needed. This is provided by a third self-modification of the primitive Force of which the principle of light, electricity, fire and heat is for us the characteristic manifestation. Even then, we can have forms of force preserving their own character and peculiar action, but not stable forms of Matter. A fourth state characterised by diffusion and a first medium of permanent attractions and repulsions, termed picturesquely water or the liquid state, and a fifth of cohesion, termed earth or the solid state, complete the necessary elements.
All forms of matter of which we are aware, all physical things even to the most subtle, are built up by the combination of these five elements. Upon them also depends all our sensible experience; for by reception of vibration comes the sense of sound; by contact of things in a world of vibrations of force the sense of touch; by the action of light in the forms hatched, outlined, sustained by the force of light and fire and heat the sense of sight; by the fourth element the sense of taste; by the fifth the sense of smell. All is essentially response to vibratory contact between force and force.
In this way the ancient thinkers bridged the gulf between pure Force and its final modifications and satisfied the difficulty which prevents the ordinary human mind from understanding how all these forms which are to his senses so real, solid and durable can be in truth only temporary phenomena and a thing like pure energy, to the senses nonexistent, intangible and almost incredible, can be the one permanent cosmic reality.
The problem of consciousness is not solved by this theory; for it does not explain how the contact of vibrations of Force should give rise to conscious sensations. The Sankhyas or analytic thinkers posited therefore behind these five elements two principles which they called Mahat and Ahankara, principles which are really non-material; for the first is nothing but the vast cosmic principle of Force and the other the divisional principle of Ego-formation. Nevertheless, these two principles, as also the principle of intelligence, become active in consciousness not by virtue of Force itself, but by virtue of an inactive Conscious Soul or souls in which its activities are reflected and by that reflection assume the hue of consciousness.
Such is the explanation of things offered by the school of Indian philosophy which comes nearest to the modern materialistic ideas and which carried the idea of a mechanical or unconscious Force in Nature as far as was possible to a seriously reflective Indian mind. Whatever it’s defects, its main idea was so indisputable that it came to be generally accepted. However the phenomenon of consciousness may be explained, whether Nature be an inert impulse or a conscious principle, it is certainly Force; the principle of things is a formative movement of energies, all forms are born of meeting and mutual adaptation between unshaped forces, all sensation and action is a response of something in a form of force to the contacts of other forms of Force. This is the world as we experience it and from this experience we must always start.
Physical analysis of Matter by modern Science has come to the same general conclusion, even if a few last doubts still linger. Intuition and experience confirm this concord of Science and Philosophy. Pure reason finds in it the satisfaction of its own essential conceptions. For even in the view of the world as essentially an act of consciousness, an act is implied and in the act movement of Force, play of Energy. This also, when we examine from within our own experience, proves to be the fundamental nature of the world. All our activities are the play of the triple force of the old philosophies, knowledge-force, desire force, action-force, and all these prove to be really three streams of one original and identical Power, Adya Shakti. Even our states of rest are only equable state or equilibrium of the play of her movement.
