For the individual centred in the mental consciousness, the awareness of the individual Soul as a passive witness of creation is a first step. From there, this awareness must eventually widen and expand beyond the limits of the individual personality. Instead of focusing on the individual limited being, the seeker can see the entire creation as residing within his own larger Self.
Sri Aurobindo describes this experience: “It is as the immanent, silent Self in all that the foundation of this cosmic consciousness can most easily be laid by the mental being, the Witness pure and omnipresent who regards all the activity of the universe as the Conscious Soul of the cosmos, Sachchidananda for whose delight universal Nature displays the eternal procession of her works. We are aware of an unwounded Delight, a pure and perfect Presence, an infinite and self-contained Power present in ourselves and all things, not divided by their divisions, not affected by the stress and struggle of the cosmic manifestation, within it all even while superior to it all. Because of that all this exists, but that does not exist because of all this; it is too great to be limited by the movement in Time and Space which it inhabits and supports. This foundation enables us to possess in the security of the divine existence the whole universe within our own being. We are no longer limited and shut in by what we inhabit, but like the Divine contain in ourselves all that for the purpose of the movement of Nature we consent to inhabit. We are not mind or life or body, but the informing and sustaining Soul, silent, peaceful, eternal, that possesses them; and this Soul we find everywhere sustaining and informing and possessing all lives and minds and bodies and cease to regard it as a separate and individual being in our own. In it all this moves and acts; within all this it is stable and immutable. Having this, we possess our eternal self-existence at rest in its eternal consciousness and bliss.”
