It is the goal of Yoga to achieve the unity of consciousness of the seeker with the Divine in all its aspects, transcendent, universal and individual. The realisation is not some kind of mental acknowledgement or an emotional attachment. And because of the infinite nature of the Divine, both in the unmanifest aspect and in the universal creation, the realisation must take on the character of an embrace of that infinity and not try to narrow down or limit the identification to one specific narrow aspect or another.
Sri Aurobindo describes the requirement: “An integral consciousness with a multiform dynamic experience is essential for the complete transformation of our nature.”
He identifies the one fundamental perception needed: “It is to realise the Divine in its essential self and truth unaltered by forms and phenomena. Otherwise we are likely to remain caught in the net of appearances or wander confusedly in a chaotic multitude of cosmic or particular aspects, and if we avoid this confusion, it will be at the price of getting chained to some mental formula or shut up in a limited personal experience. The one secure and all-reconciling truth which is the very foundation of the universe is this that life is the manifestation of an uncreated Self and Spirit, and the key to life’s hidden secret is the true relation of this Spirit with its own created existences. There is behind all this life the look of an eternal Being upon its multitudinous becomings; there is around and everywhere in it the envelopment and penetration of a manifestation in time by an unmanifested timeless Eternal.”
The seeker cannot be satisfied with a mental realisation; there must be the vivid experience in the consciousness. “For what Yoga searches after is not truth of thought alone or truth of mind alone, but the dynamic truth of a living and revealing spiritual experience. There must awake in us a constant indwelling and enveloping nearness, a vivid perception, a close feeling and communion, a concrete sense and contact of a true and infinite Presence always and everywhere. That Presence must remain with us as the living, pervading Reality in which we and all things exist and move and act, and we must feel it always and everywhere, concrete, visible, inhabiting all things; it must be patent to us as their true Self, tangible as their imperishable Essence, met by us closely as their inmost Spirit. To see, to feel, to sense, to contact in every way and not merely to conceive this Self and Spirit here in all existences and to feel with the same vividness all existences in this Self and Spirit, is the fundamental experience which must englobe all other knowledge.”
“This infinite and eternal Self of things is an omnipresent Reality, one existence everywhere; it is a single unifying presence and not different in different creatures; it can be met, seen or felt in its completeness in each soul or each form in the universe. For its infinity is spiritual and essential and not merely a boundlessness in Space or an endlessness in Time; the Infinite can be felt in an infinitesimal atom or in a second of time as convincingly as in the stretch of the aeons or the stupendous enormity of the intersolar spaces. The knowledge or experience of it can begin anywhere and express itself through anything; for the Divine is in all, and all is the Divine.’
