"That which we know as Yoga is the method by which evolution is quickened in the individual, and all the powers of the Self, up to the threshold of divinity, may by it be brought into manifestation in the man of the present. That is why Yoga training was necessary for the ancient scientist; he must develop in himself the three aspects of God, if he were to understand them as manifested in the universe around him. Now, at our own stage of evolution, it is specially the life of Brahmâ—or the Brahmâ aspect of God—with which the human mind is coming into touch, because the mind in man is the reflection of the universal mind in Kosmos. That life is the life that is the force in the atom, that vivifies every atom, nay, that brings the atom into existence, as we shall see, and remains during the whole of the growth of the universe as the fundamental life that keeps those atoms as active particles building up innumerable forms."
