Vaisampayana continued,--“And as the Pandavas were going away from the assembly, the wicked king Duryodhana from excess of joy mimiced by his own steps the playful leonine trade of Bhima. Then Vrikodara, half turning towards the king said, Think not ye fool that by this thou gainest any ascendency over me slay thee shall I soon with all thy followers, and answer thee, recalling all this to thy mind. And beholding this insult offered to him, the mighty and proud Bhima, suppressing his rising rage and following the steps of Yudhishthira, also spake these words while going out of the Kaurava court, ‘I will slay Duryodhana, and Dhananjaya will slay Karna, and Sahadeva will slay Sakuni that gambler with dice. I also repeat in this assembly these proud words which the gods will assuredly make good, if ever we engage in battle with the Kurus, I will slay this wretched Duryodhana in battle with my mace, and prostrating him on the ground I will place my foot on his head. And as regards this (other) wicked person--Dussasana who is audacious in speech, I will drink his blood like a lion.
