sAkshi Chaitanya

 When I know any object, in between two vrttis , I am. 

I am continues, even if the vrttis are changing.

I am the changeless knower, in between two changing vrttis, I am knower of X (pramatha), knower of Y (pramatha), and in between these vrttis, I am. This I am is self revealing, and continous and unchanging in all 3 states, I am always the I.

This I is sakshi brahman, which lights up the universe.

When I say this is somethiing, I myself morph into knower, known and vrtti.
