The human mind creates distinctions and tends to oppose them, one to another. Thus, there is a separation between the Eternal and the temporal, between the Infinite Existence and the finite, transitory forms of the world. The mind separates past, present and future and, when it becomes absorbed in a particular motion, action or process, it loses awareness of other aspects of existence.
The supermind, however, resides always in a full awareness of the Eternal, while at the same time it has the ability to choose and create forms, beings and actions in the manifestation of the universal creation through the instrumentality of Time.
Sri Aurobindo describes the nature and character of the supermind: “It does not live only in what it is and thinks and does selectively in the present or on one plane only of being; it does not feed its existence only on the present or the continual succession of moments to whose beats we give that name. It does not see itself only as a movement of Time or of the consciousness in time or as a creature of the perpetual becoming. It is aware of a timeless being beyond manifestation and of which all is a manifestation, it is aware of what is eternal even in Time, it is aware of many planes of existence; it is aware of past truth of manifestation and of much truth of being yet to be manifested in the future, but already existing in the self-view of the Eternal. It does not mistake the pragmatic reality which is the truth of action and mutation for the sole truth, but sees it as a constant realisation of that which is eternally real. It knows that creation whether on the plane of matter or of life or of mind or of supermind is and can be only a self-determined presentation of eternal truth, a revelation of the Eternal, and it is intimately aware of the pre-existence of the truth of all things in the Eternal. This seeing conditions all its pragmatic thought and its resultant action. The maker in it is a selective power of the seer and thinker, the self-builder a power of the self-seer, the self-expressing soul a power of the infinite spirit. it creates freely, and all the more surely and decisively for that freedom, out of the infinite self and spirit.”
