אות - סז

One who does not listen and submit to the words of the true wise men can become insane. For the primary madness of all the insane is only because they do not submit and listen to the words of those who have understanding. For the insane person — had he listened and submitted to the words of others who are the possessors of understanding — he certainly would not have been insane at all. For even though according to the spirit of folly and insanity that is within him his own view seems correct — nevertheless, if he had submitted to the view of others who have understanding, he would have seen that his view was folly. And this is the essence of the correction for insanity.
