Albert Einstein’s mathematical discovery of the four-dimensional plane of existence, the ‘Spacetime’ or ‘Space-Time Continuum’, as it is called, is an evolutionary breakthrough in the realm of Science. Since the plane of ‘Spacetime’ or ‘Space-Time Continuum’ is a mathematical structure, the most celebrated scientist finds it to be a physical plane of existence. Mysteriously enough, it is not physically visible. Physics is answerless on its invisibility. Transcending Einstein, Sri Aurobindo, a ‘yogi of the unknown eternal heights’ reveals ‘Space’, in his epic Savitri, to be ‘a vast experiment of Soul’, the Divine Consciousness in the being of Man. Furthermore, it is the Soul of the Universe, ‘Vishwatman’, as the Rishis call it. In such a vision of space the mystery of the invisibility of Spacetime disappears. The plane of Spacetime is the plane of integral existence to which mankind is yet to evolve. Man is subject to the divisive principle of Consciousness as a result of which the plane of Spacetime is not visible to him. On account of the subjection to the divisive principle of consciousness Newton could find Space and Time to be two incompatible realities. Man is required to evolve his latent spiritual consciousness to attain the integrality of Consciousness for the vision of the plane of Spacetime. He has to undertake the yoga to attain, first, the silent state of mind to ascend the planes of the spiritual and Supramental Consciousnesses, says Sri Aurobindo. In the silent state of mind, the divisiveness of consciousness ceases to have its hold as a result of which man is able to visualise the plane of Spacetime, the Spacetime which is all the more clearly visible when he continues to ascend the higher planes of the spiritual consciousness. On the plane of the spiritual consciousness there is a movement towards the integrality of consciousness, and consequently ‘Space’ is found to be ‘a vast experiment of Soul’ in this movement, the movement which is, in fact, the ascent of the yogic consciousness.
