12.84.32

yastu saṃharate tāni bhartuḥ priyacikīrṣayā |
samānasukhaduḥkhaṃ taṃ pṛcchedartheṣu mānavam || 32 ||

A man of wicked heart and possessed of no learning may set his hand to work but he fails to ascertain what the results will be of his work. A king should never repose trust on a minister that is not devoted to him. He should, therefore, never disclose his counsels to a minister that is not devoted to him. Such a wicked minister, combining with the other ministers of the king, may ruin his master, like a fire consuming a tree by entering its entrails through the holes in its body with the aid of the wind. Giving way to wrath, a master may one day pull down a servant from his office or reprove him, from rage, in harsh words, and restore him to power again. None but a servant devoted to the master can bear and forgive such treatment. Ministers also become sometime highly offended with their royal masters. That one, however, amongst them, who subdues his wrath from desire of doing good to his master,--that person who is a sharer with the king of his weal and woe,--should be consulted by the king in all his affairs. A person who is of crooked heart, even if he be devoted to his master and possessed of wisdom and adorned with. numerous virtues, should never be consulted by the king. One who is allied with foes and who does not regard the interests of the king's subjects, should be known as an enemy. The king should never consult with him.
