Once you get the knack of witnessing without judgment you will be surprised: the moment you are utterly a witness all the thoughts disappear. There is simply a plain white screen and no thoughts. This is the first experience, that you have come to the door of meditation. Just go on looking at the white screen. Don’t do anything.
Consciousness has a nature — if it cannot find any object which prevents it, then it goes round and comes back to you. In existence everything moves in a circle. Remember that: nothing moves in a straight line. If there is no obstacle, the consciousness comes back to its own source. And the consciousness coming back to one’s own source, for the first time sees who is there, who has always been there. That is your real being.
