The difficulty is to free the mind from the known so that it can discover what is new all the time. A great mathematician once told of how he had been working on a problem for a number of days and could not find the solution. One morning, as he was taking a walk as usual, he suddenly saw the answer. What had happened? His mind, being quiet, was free to look at the problem, and the problem itself revealed the answer. One must have information about a problem, but the mind must be free of that information to find the answer.
