Questioner: ...why does one run away? What is one escaping from?"
Krishnamurti: From your own loneliness, your own emptiness, from what you are. If you run away without seeing what is, you obviously cannot understand it; so first you have to stop running, escaping and only then can you watch yourself as you are. But you cannot observe what is if you are always criticizing it, if you like or dislike it. You call it loneliness and run away from it; and the very running away from what is is fear. You are afraid of this loneliness, of this emptiness, and dependence is the covering of it. So fear is constant; it is constant as long as you are running away from what is. To be completely identified with something, with a person or an idea, is not a guarantee of final escape, for this fear is always in the background. It comes through dreams, when there is a break in identification; and there is always a break in identification, unless one is unbalanced.
Questioner: Then my fear arises from my own hollowness, my insufficiency. I see that all right, and it is true; but what am I to do about it?
Krishnamurti: You cannot do anything about it. Whatever you do is an activity of escape. That is the most essential thing to realize. Then you will see that you are not different or separate from that hollowness. You are that insufficiency. The observer is the observed emptiness. Then if you proceed further, there is no longer calling it loneliness; the terming of it has ceased. If you proceed still further, which is rather arduous, the thing known as loneliness is not; there is a complete cessation of loneliness, emptiness, of the thinker as the thought. This alone puts an end to fear.
