The ‘I-I’ is always there. There is no knowing it. It is not a new knowledge acquired.

Ramana Maharishi:  The ‘I-I’ is always there. There is no knowing it. It is not a new knowledge acquired. What is new and not here and now will be evanescent only. The ‘I’ is always there. There is obstruction to its knowledge and it is called ignorance. Remove the ignorance and knowledge shines forth. In fact this ignorance or even knowledge is not for Atman. They are only overgrowths to be cleared off. That is why Atman is said to be beyond knowledge and ignorance. It remains as it naturally is - that is all.
