“To learn, to discover something fundamental you must have the capacity to go deeply. If you have a blunt instrument, a dull instrument, you cannot go deeply. So what we are doing is sharpening the instrument, which is the mind—the mind which has been made dull by all this justifying and condemning. You can penetrate deeply only if your mind is as sharp as a needle and as strong as a diamond.”

J. Krishnamurti, Freedom From The Known (Page 54)
