For the wise, who have risen above the ordinary faults of human life, it matters little if they find fault, but they are the ones who do not criticize. They, as a rule, overlook all that seems undesirable, and that action of overlooking itself prevents all the undesirable impressions from penetrating through their hearts. There is a natural tendency in man as in the animal to protect his heart from all hurt or harm, but that is the external heart. If man only knew what harm is brought to one's being by letting any undesirable impression enter the heart, he also would adopt the above-mentioned policy of the wise, to overlook.
