76. Should one find a man who points out faults and who reproves, let him follow such a wise and sagacious person as one would a guide to hidden treasure. It is always better, and never worse, to cultivate such an association.
77. Let him admonish, instruct and shield one from wrong; he, indeed, is dear to the good and detestable to the evil.
