It is third question of self-inquiry. As I wrote the story of these questions and answers, in the year of 1902 Sivprkasam pilli met maharishi Ramana on Arunachalla hill. He was in silence in Vrupaksa cave.Maharishi gave the answers by writing. It is the third question.
What is nature of awarness?
The nature of awarness is existence-consciousness- bliss.
Comment; we can not explain it in language, but as maharishi explained it ,beacuse the Rishes of Vadas gave the name as sat-chit -ananda. meaning existance ,consciousness and bliss. this is our real nature which does not born and does not dies, it is form of our sou or sprite.
