Sri Aurobindo writes in his book Essays Divine and Human: “Matter, Life, Mind, Supermind or Gnosis, and beyond these the quadruple power of a supreme Being-Consciousness-Force-Bliss—these are the grades of the evolutionary ascent from inconscience to the Superconscience.” (pg.249) He also writes that “The evolution of the earth nature is not finished because it has manifested only three powers out of the seven-fold scale of consciousness that is involved in manifested Nature. It has brought out from its apparent inconscience only the three powers of Mind and Life and Matter.” (pg.244) Can we infer from this that after Supermind, the luminous planes of Sat, Chit and Ananda will be evolving here on earth🧐? Of course, the question is mainly to know if I have correctly comprehended Sri Aurobindo’s vision of evolution and its fulfilment here on earth

Absolutely so. After the Supramental Manifestation and the Supramental body there will be the Manifestation of Bliss and the bliss body. Sri Krishna worked for that eventual fulfilment but the base of Truth Consciousness has to be first firmly established upon earth. 

The difference however will be that right now this evolutionary emergence is a painful process involving much struggle due to the hard grip of ignorance.  With the Supramental Manifestation the further emergence will be a conscious happy process undertaken in freedom and delight. Whether and what way the further Manifestation beyond the Bliss Self will take place is difficult to say since creation has begun with delight. With the full recovery of the delight of existence there would likely be an unending play of existence and consciousness in countless bodies of bliss, the Maharasa envisaged by the Hindu mystics.
