Nisargadatta Maharaj Quote

God is only an idea in your mind. The fact is you. The only thing you know for sure is: 'here and now I am.' Remove the 'here and now' the 'I am' remains, unassailable. (…). All I can say truly is: 'I am,' all else is inference (…). The sense 'I am' is the manifestation of a deeper cause, which you may call self, God, Reality or by any other name.
