If I am learning something like learning physics or chemistry or maths means who is learning? Is it Atman or my brain?
If Atman means why can't it (Atman) realize after death that I belong to this body and then I will enter back to this same body.
If it is just my brain, my brain is learning about Brahman now, then how my Atman will remember that oh okay I am actually Brahman, so I should merge with brahman and this body is not real.
I am looking for connectivity between brain and Atman. How brain will send the information to my Atman that I am Brahman.
