Sri Aurobindo describes a transitional process from our current state of mentality, based in ignorance, groping around in darkness to find truth and light, to a new status based in knowledge, sourced from the supramental realm that sees the oneness and the multiplicity for what they are and their relations to one another. There can be two separate lines of development. The first is the expansion and development of the mind to a wider, fuller, more powerful and light-filled instrument of the supermind; the second is the development of beings who have the “native” action of the supermind in all its fullness of power and knowledge. Both of these are likely to be part of the transitional phase and will provide the links between our present status and that future reality of existence.
Sri Aurobindo writes: “A new humanity means for us the appearance, the development of a type or race of mental beings whose principle of mentality would be no longer a mind in the Ignorance seeking for knowledge but even in its knowledge bound to the Ignorance, a seeker after Light but not its natural possessor, open to the Light but not an inhabitant of the Light, not yet a perfected instrument, truth-conscious and delivered out of the Ignorance. Instead, it would be possessed already of what could be called a mind of Light, a mind capable of living in the truth, capable of being truth-conscious and manifesting in its life a direct in place of an indirect knowledge. Its mentality would be an instrument of the Light and no longer of the Ignorance. At its highest it would be capable of passing into the supermind and from the new race would be recruited the race of supramental beings who would appear as the leaders of the evolution in earth-nature. Even, the highest manifestations of a mind of Light would be an instrumentality of the supermind, a part of it or a projection from it, a stepping beyond humanity into the superhumanity of the supramental principle. Above all, its possession would enable the human being to rise beyond the normalities of his present thinking, feeling and being into those highest powers of the mind in its self-exceedings which intervene between our mentality and supermind and can be regarded as steps leading towards the greater and more luminous principle. This advance like others in the evolution might not be reached and would naturally not be reached at one bound, but from the very beginning it would be inevitable: the pressure of the supermind creating from above out of itself the mind of Light would compel this certainty of the eventual outcome. The first gleamings of the new Light would carry in themselves the seed of its highest flamings; even in the first beginnings the certainty of their topmost powers would be there; for this is the constant story of each evolutionary emergence: the principle of its highest perfection lies concealed in the involution which precedes and necessitates the evolution of the secret principle.”
