Mbh 5.4.1a

“Drupada said, ‘O mighty-armed one, it will, without doubt, be even as thou hast said! Never will Duryodhana give up the kingdom by peaceful means, and Dhritarashtra, who dotes on his son, will follow him in his wish. And so will Bhishma and Drona from imbecility, and Karna and Sakuni from folly. The words of Valadeva command themselves to my judgment; the course pointed out by him should, indeed, be followed by a man who desires peaceful settlement. But Duryodhana should never be addressed in mild words. Vicious by nature, he, I believe cannot be brought to reason by mildness. In respect of an ass, mildness is in place; but in respect of animals of the bovine species, severity should be resorted to. If any one were to speak mild words to Duryodhana, vicious by nature that wicked wight would consider the speaker to be an imbecile person. If a mild course is adopted towards him, the fool will think that he has won. Let us do even this, let us make preparations; let us send word to our friends that they may collect an army for us. Let speedy messengers go to Salya, and Dhrishtaketu, and Jayatsena, and the prince of the Kekayas. Duryodhana also, on his part, will send word to all the kings, Rightminded persons, however, respond to the request of those that first beseech them. Therefore, I ask you to make haste in first preferring your suit to these rulers of men. Meseems that a great undertaking is awaiting us. Quickly send word to Salya, and to the kings under him, and to king Bhagadatta of immeasurable valour residing on the eastern sea-coast, and to fierce Hardikya, and Ahuka, and the king of the Mallas of powerful understanding, and Rochamana.
