When you investigate the one who's interested in a life in the world, and you find out that...that one is just as much a perceived phenomenon as the 'world' is...somehow through this discovery the Self is revealed...where are your attachments in that moment of recognition?...where is your desire?...where are your fears?...where is your self-interest?...everything is blown away.
The senses are still functioning, the images of the world are still there...but the attachments and the fears are gone, because the one who would experience them disappeared...you are now the Self...This is what Bhagavan means when he says...
'When you are the Self, the world is not seen'...
