Mbh 12.132.2b

When slanderous converse goes on, one should close one's ears or leave the place outright. Slanderous converse is the characteristic of wicked men. It is an indication of depravity. They, on the other hand, O king, who speak of the virtues of others in assemblies of the good, are good men. As a pair of sweet-tempered bulls governable and well-broken and used to bear burthens, put their necks to the yoke and drag the cart willingly, even so should the king bear his burthens (in seasons of distress). Others say that a king (at such times) should conduct himself in such a way that he may succeed in gaining a large number of allies. Some regard ancient usage as the highest indication of righteousness. Others, viz., they that are in favour of the conduct pursued by Sankha, towards Likhita, do not hold this opinion. They do not advance such an opinion through either malice or covetousness[399]. Examples are seen of even great Rishis who have laid down that even preceptors, if addicted to evil practices, should be punished. But approvable authority there is none for such a proposition. The gods may be left to punish such men when they happen to be vile and guilty of wicked practices. The king who fills his treasury by having recourse to fraudulent devices, certainly falls away from righteousness. The code of morality which is honoured in every respect by those that are good and in affluent circumstances, and which is approved by every honest heart, should be followed. He is said to be conversant with duty who knows duty as depending on all the four foundations. It is difficult to find out the reasons on which duties stand even as it is difficult to find out the legs of the snake.[400] As a hunter of beasts discovers the track of a shaft-struck deer by observing spots of blood on the ground, even so should one seek to discover the reasons of duties. Thus should a man tread with humility along the path trod by the good.
