In The Life Divine, Sri Aurobindo describes the process of “involution and evolution” whereby the supreme powers of existence have become involved in Matter, and then undertake an evolution, a series of steps of self-finding and expansion to integrate Matter with Spirit.
This implies that the development to the next level of consciousness is essentially inevitable in the earth evolution. It becomes then a matter of time and process. Sri Aurobindo describes this at the end of the book The Mother as follows:
“The supramental change is a thing decreed and inevitable in the evolution of the earth-consciousness; for its upward ascent is not ended and mind is not its last summit.”
We can participate and cooperate in this change through a psychological process of aspiration and receptivity from our side and a corresponding response from the consciousness operating on the higher planes. “But that the change may arrive, take form and endure, there is needed the call from below with a will to recognise and not deny the Light when it comes, and there is needed the sanction of the Supreme from above.”
It is the power of the Divine Shakti that provides the impetus for this change. Without the Mother’s Force in action, human effort cannot achieve the result on its own. “The power that mediates between the sanction and the call is the presence and power of the Divine Mother. The Mother’s power and not any human endeavor and tapasya can alone rend the lid and tear the covering and shape the vessel and bring down into this world of obscurity and falsehood and death and suffering Truth and Light and Life divine and the immortal’s Ananda.”
