5.37.41

dhārtarāṣṭrā vanaṃ rājanvyāghrāḥ pāṇḍusutā matāḥ |
mā vanaṃ chindhi savyāghraṃ mā vyāghrānnīnaśo vanāt || 41 ||

'Behold the evils of a rupture with the Pandavas which would sadden the very gods with Sakra. These are, first, enmity between them that are all thy sons; secondly, a life of continued anxiety; thirdly, the loss of the fair fame of the Kurus; and lastly, the joy of those that are thy enemies. The wrath of Bhishma, O thou of the splendour of Indra, of Drona, and the king Yudhishthira, will consume the whole world, like a comet of large proportions falling transversely on the earth. Thy hundred sons and Karna and the sons of Pandu can together rule the vast earth with the belt of the seas. O king, the Dhartarashtras constitute a forest of which the Pandavas are, I think, tigers. O, do not cut down that forest with its tigers! O, let not the tigers be driven from that forest! There can be no forest without tigers, and no tigers without a forest. The forest shelters the tigers and tigers guard the forest!'
