Thought must be used – we all agree to that. Thought has its value, its importance, its place. Can a human being live in a state of mind which is so tremendously active that it is empty? A highly tuned drum is empty inside. When you strike it, it gives the right note. It is always empty, otherwise it will not give you the right note. So is it possible for the mind to be so totally empty? It is only out of emptiness that you can see the beauty of life, the beauty of a tree. You cannot see if you are not empty. This means no commitment, always learning, not accumulating; it means observing, being awake, being aware without any choice, and therefore giving tremendous attention.
