Thought is born of experience and knowledge, and there is nothing sacred whatsoever about thought. Thinking is materialistic, it is a process of matter. And we have relied on thinking to solve all our problems in politics and religions and in our relationships. Our brains, our minds, are conditioned, educated to solve problems. Thinking has created problems and then our brains, our minds, are trained to solve them with more thinking. All problems are created, psychologically and inwardly, by thought. Follow what is happening. Thought creates the problem, psychologically; the mind is trained to solve problems with further thinking, so thought in creating the problem then tries to solve it. So it is caught in a continuous process, a routine. Problems are becoming more and more complex, more and more insoluble, so we must find out if it is at all possible to approach life in a different way, not through thought because thought does not solve our problems; on the contrary thought has brought about greater complexity. 

We must find out - if it is possible or not - whether there is a different dimension, a different approach, to life altogether. And that is why it is important to understand the nature of our thinking. Our thinking is based on remembrance of things past - which is thinking about what happened a week ago, thinking about it modified in the present, and projected into the future. This is actually the movement of our life. So knowledge has become all-important for us but knowledge is never complete. Therefore knowledge always lives within the shadow of ignorance. That is a fact. It is not the speaker's invention or conclusion, but it is so.
