Human beings have too much understanding. Too much understanding, too much have problems. Little bit understanding, little problem. If you don’t know, no problem! That’s the point: if you don’t know, no problem. So Don’t-Know mind is very important.
Much understanding means somebody’s idea; it’s somebody’s idea that makes problems for me. Many desires, cannot get the desires, then get angry, then ignorance appears, make ignorant actions – stupid actions. So then you have problems. So Buddha is teaching us, you must attain your true self. If I ask you, “Who are you?”, what do you say? You know what I mean? Human beings have much understanding, but don’t understand anything!
