Socrates says, "Man, know thyself." That is the teaching of all the buddhas: Know thyself. How are you going to know yourself? If mind remains too much and goes on clamoring around you, goes on making great noise, you will never hear the still small voice within. You have to become disidentified with the mind.
George Gurdjieff used to say, "My whole teaching can be condensed into one word, and that is disidentification." He is right. Not only his teaching can be condensed into one word, all the teaching of all the masters can be condensed into one word: disidentification. Don't be identified with the mind.
