The practice of meditation is largely based on some kind of sacrifice and openness. Such sacrifice is necessary and has to be personally experienced. Ordinarily, we might sacrifice something for the sake of developing goodness, or because we are willing to suffer on behalf of humanity. However, the sacrifice that has been recommended in the Buddhist tradition is to sacrifice something without any purpose. . . . Sacrificing something without a purpose is outrageous and precisely heroic and fantastic; it is very beautiful. The practice of meditation is sacrifice and openness without techniques, without means, without gloves, pliers or hammers. You have to use your bare hands, bare feet, bare head, to relate with the whole thing.
