For knowing our thoughts, enormous amount of awareness is required, the driving force behind each action of ours has to be known, driving force behind each word we utter has to be known..one has to “stop” and let the thoughts “pass”. This “stopping” is very important. We keep keep moving simultaneous with the thoughts, we are parallel to the thoughts, that is why we do not know. The moment we stop, we can see them pass, hear them, see them and then do away with them. This stopping has to be learnt.
