Mbh 1.203.3a

“Duryodhana said. ‘Let us, O father, by means of trusted and skilful and adroit Brahmanas, seek to produce dissensions between the sons of Kunti and Madri. Or, let king Drupada and his sons, and all his ministers of state, be plied with presents of large wealth, so that they may abandon the cause of Yudhishthira, the son of Kunti. Or, let our spies induce the Pandavas to settle in Drupada’s dominions, by describing to them, separately, the inconvenience of residing in Hastinapura, so that, separated from as, they may permanently settle in Panchala. Or, let some clever spies, full of resources, sowing the seeds of dissension among the Pandavas, make them jealous of one another. Or, let them incite Krishna against her husbands. She has many lords and this will not present any difficulty. Or, let some seek to make the Pandavas themselves dissatisfied with Krishna, in which case Krishna also will be dissatisfied with them. Or, let, O king, some clever spies, repairing thither, secretly compass the death of Bhimasena. Bhima is the strongest of them all. Relying upon Bhima alone, the Pandavas used to disregard us, of old. Bhima is fierce and brave and the (sole) refuge of the Pandavas. If he be slain, the others will be deprived of strength and energy. Deprived of Bhima who is their sole refuge, they will no longer strive to regain their kingdom. Arjuna, O king, is invincible in battle, if Bhima protecteth him from behind. Without Bhima, Arjuna is not equal to even a fourth part of Radheya. Indeed, O king, the Pandavas conscious of their own feebleness without Bhima and of our strength would not really strive to recover the kingdom. Or, if, O monarch, coming hither, they prove docile and obedient to us, we would then seek to repress them according to the dictates of political science (as explained by Kanika). Or, we may tempt them by means of handsome girls, upon which the princess of Panchala will get annoyed with them.
