The creative thinking, or renewing thinking, is the self-forgetful way of thinking.
But in order to, that the thought can renew itself, it must be finished. That which is finished ceases, and therefore there is a renewal.
To finish thoughts, so that they can end and renew themselves, is equivalent with the process, where the thinker understands himself, because the thinker and the thought are not two separated processes.
And in order to understand yourself, you must partly become yourself present in passive listening, partly slow the speed of your thoughts down.
