If you are hearing for the first time this statement that you must be free of thought, you may say, " Poor chap, he is crazy." But if you have really listened, not only this time but for the many years during which some of you have perhaps read all about it, you will know that what is being said has an an extraordinary vitality, a penetrating truth. Only the mind that has emptied itself of the known is creative. That is creation. What it creates has nothing to do with it. Freedom from the known is the state of a mind that is in creation. How can a mind that is in creation be concerned with itself? Therefore, to understand that state of mind, you have to know yourself, you have to observe the process of your thinking - observe it, not to alter it, not to change it, but just observe it as you see yourself in a mirror. When there is freedom, then you can use knowledge and it will not destroy humanity. But when there is no freedom and you make use of knowledge, you create misery for everybody, whether you are in Russia, in America, in China or anywhere else. I call that mind serious that is aware of the conflict of the known and is not caught in it, not trying to modify it, to improve the known; for on that path there is no end to sorrow and misery.
