You know that you know nothing. Find out that knowledge.
All that is required to realise the Self is to “Be Still.
The question 'Who am I?' is not really meant to get an answer, the question 'Who am I?' is meant to dissolve the questioner.
To know one's Self is to be blissful always.
The place where even the slightest trace of the 'I' does not exist, alone is Self.
Guru, God and Self are One
