Is There Security at All Psychologically?

If you have observed, whatever we do, act, emotionally or non-emotionally, all our activities are based on thought. Now thought is limited. I do not know if you accept that, or if you are aware of it. Why is it limited? We think it can do everything: climb the Everest, go to the Moon, go to the depths of the sea - thought is the most active, most important, vital thing in our life. All our education is to cultivate knowledge and encourage thinking clearly, if you can, and act from thought. And thought has created not only the technological world, but also it has created wars, not only marvellous surgery but also thought has created conflict between two human beings. Follow, these are facts. Thought has created the quick transportation. Thought also has created the destruction of all human relationships. And one must, if you are at all serious, go into this question: why thought has become so urgently important? As we are talking together you are thinking. Right? You are following verbally. So the activity of thought is going on; trying to understand what is being said, trying to judge whether it is right or wrong, what value has it in daily life - you are all the time enquiring with the instrument of thought. And thought has created heaven and hell, not only the Christian world of Hell and Heaven, but also actual hell and heaven: the enormous poverty, the misery, the confusion, the uncertainty of existence.
