When one is confronted with a problem, there is a tendency to classify
it, to find a similar problem in one's memory, either previously
experienced or heard about, and to apply the previous problem's
solution to the present problem. As soon as this process starts, the
perception of the present problem fades and distorts, and the present
problem is not solved. If one is presented with a problem that is
entirely outside one's previous experience and knowledge then one must
apply one's whole attention to it, and make a creative solution. Can
one treat every problem as though it were fresh and completely new?

else speaks of opening the hand of thought.
