For the complete mutation in consciousness to take place you must deny analysis and search, and no longer be under any influence, which is immensely difficult. The mind, seeing what is false, has put the false aside completely, not knowing what is true. If you already know what is true, then you are merely exchanging what you consider is false for what you imagine is true. There is no renunciation if you know what you are going to get in return. There is only renunciation when you drop something not knowing what is going to happen. That state of negation is completely necessary. Please follow this carefully, because if you have gone so far you will see that in that state of negation you discover what is true; because, negation is the emptying of consciousness of the known. After all, consciousness is based on knowledge, on experience, on racial inheritance, on memory, on the things one has experienced. Experiences are always of the past, operating on the present, being modified by the present and continuing into the future. All that is consciousness, the vast storehouse of centuries. It has its usefulness in mechanical living only. It would be absurd to deny all the scientific knowledge acquired through the long past. But to bring about a mutation in consciousness, a revolution in this whole structure, there must be complete emptiness. And that emptiness is possible only when there is the discovery, the actual seeing of what is false. Then you will see, if you have gone so far, that emptiness itself brings about a complete revolution in consciousness: it has taken place.
