So, thinking is always a conditioned response, thinking is a process of response to a challenge. The challenge is always new; but thinking, which is a response derived from memory, is always the old revivified. It is very important to understand this. Thinking can never be new, because thinking is the response of memory, and this response of memory becomes vital when it meets the new and derives life from the new. But thinking in itself is never new. Therefore, thinking can never be creative, because it is always the response of memory. Now, our minds, our thoughts, are wandering all over the place, and we want to bring about order. As I have explained, this cannot be done by control; because, the moment you control it, your mind becomes exclusive, isolated. If you merely emphasize one thought and exclude all others, there is an isolating process going on. Therefore, such a mind can never be free. It can isolate itself, but isolation is not freedom. A controlled mind is not a free mind.
