Surely, it is only when the mind is creatively empty that it is capable of finding out whether there is an ultimate reality or not. But, the mind is never creatively empty; it is always acquiring, always gathering, living on the past or in the future, or trying to be focused in the immediate present: it is never in that state of creativeness in which a new thing can take place. As the mind is a result of time, it cannot possibly understand that which is timeless, eternal.
