Mbh 4.4.2c

Let none, when the king is engaged in doing anything (in respect of his servants) come forward pressing himself zealously before others, for even if the aggrieved be very poor, such conduct would still be inexcusable.[7] It behoveth no man to reveal to others any lie the king may have told inasmuch as the king bears ill will to those that report his falsehoods. Kings also always disregard persons that regard themselves as learned. No man should be proud thinking--“I am brave, or, I am intelligent,” but a person obtains the good graces of a king and enjoys the good things of life, by behaving agreeably to the wishes of the king. And, O Bharata, obtaining things agreeable, and wealth also which is so hard to acquire, a person should always do what is profitable as well as pleasant to the king. What man that is respected by the wise can even think of doing mischief to one whose ire is a great impediment and whose favour is productive of mighty fruits? No one should move his lips, arms and thighs, before the king. A person should speak and spit before the king only mildly. In the presence of even laughable objects, a man should not break out into loud laughter, like a maniac; nor should one show (unreasonable) gravity by containing himself, to the utmost. One should smile modestly, to show his interest (in what is before him). He that is ever mindful of the king’s welfare, and is neither exhilarated by reward nor depressed by disgrace, is alone worthy of dwelling in a royal household. That learned courtier who always pleaseth the king and his son with agreeable speeches, succeedeth in dwelling in a royal household as a favourite. The favourite courtier who, having lost the royal favour for just reason, does not speak evil of the king, regains prosperity. The man who serveth the king or liveth in his domains, if sagacious, should speak in praise of the king, both in his presence and absence.
