I guess this is the same as the cidghana (dense consciousness) described below in the paragraph from the SOY chapter on "Vijnana or Gnosis". This may also be the state where one recovers the original Samjnana (Supramental Sense)

To the envisaging mind there are three powers of the Vijnana. Its supreme power knows and receives into it from above all the infinite existence, consciousness and bliss of the Ishwara; it is in its highest height the absolute knowledge and force of eternal Sachchidananda. Its second power concentrates the Infinite into a dense luminous consciousness, caitanyaghana or cidghana, the seed-state of the divine consciousness in which are contained living and concrete all the immutable principles of the divine being and all the inviolable truths of the divine conscious-idea and nature.

Rishabchand in the chapter on Integral Perfection in his book "Integral Yoga" describes it as follows (the italics are from Sri Aurobindo's book "The Supramental Manifestation" )

The body, filled with the gnostic light and the gnostic force, vijñāna -jyoti and vijñāna-sakti, its cells illumined and electrified, and its consciousness fully developed to respond even to the least call of Spirit, may acquire "new means and ranges of communication with other bodies, new processes of acquiring knowledge, a new aesthesis, new potencies of manipulation of itself and objects. It might not be impossible for it to possess and disclose means native to its own constitution, substance or natural instrumentation for making the far near and annulling distance, cognising what is now beyond the body's cognisance, acting where action is now out of its reach or its domain, developing subtleties and plasticities which could not be permitted under present conditions to the needed fixity of a material frame."
