The fathomless zero that occupied the world here refers to the earth that is wheeling as if abandoned after one of the pralayas. It is the story of creation upon earth as we see it mentioned a few lines below. Even in the very second line we have a word about the ‘divine event’ yet to take place which is about the death of Satyavan and his return to life.
Involution refers to the whole universe or universes. Evolution and at its farther end the supramental transformation refers to the drama going on upon earth.
Affectionately,
Alok Da
