Mahabharata Shalya Parva Chapter 31

Mahabharata Shalya Parva (Hrada Pravesa Parva) Chapter 31 "Sanjaya said, 'After those three car-warriors had left that spot, the Pandavas arrived at that lake within which Duryodhana was resting himself. Having reached the banks of the Dvaipayana lake, O chief of Kuru's race, they beheld that receptacle of waters enchanted by thy son. Then Yudhishthira, addressing Vasudeva, said, "Behold, the son of Dhritarashtra hath applied his power of illusion to these waters! Having enchanted the waters, he lieth within them. He can have now no fear (of injury) from man! Having invoked a celestial illusion, he is now within the waters! By an act of deception, that wight conversant with every deception hath sought this refuge! He shall not, however, escape me with life! Even if the wielder of the thunderbolt himself aid him in battle, people, O Madhava, shall yet behold him slain today!" "'Vasudeva said, "With thy own powers of illusion, O Bharata, destroy this illusion of Duryodhana who is an adept in it! One conversant with illusion should be slain with illusion! This is the truth, O Yudhishthira! With acts and means and applying thy power of illusion to these waters, slay, O chief of the Bharatas, this Suyodhana, who is the very soul of illusion! With acts and means Indra himself slew the Daityas and the Danavas! Vali himself was bound by that high-souled one (Upendra), with the aid of many acts and means! The great Asura Hiranyaksha, as also that other one, Hiranyakasipu, was slain by the aid of many acts and means. Without doubt, O king, Vritra also was slain by the aid of acts! Similarly was the Rakshasa Ravana of Pulastya's race, with his relatives and followers, slain by Rama! Relying upon acts and contrivances, do thou also display thy powers! Those two ancient Daityas, Taraka and Viprachitti of great energy, were in ancient times, O king, slain by the aid of acts and means! Similarly, Vatapi and Ilwala, and Trisiras, O lord, and the Asuras Sunda and Upasunda, were all slain by the aid of means! Indra himself enjoys heaven by the aid of acts and means! Acts are very efficacious, O king, and nothing else so, O Yudhishthira! Daityas and Danavas and Rakshasas and kings had been slain by the aid of acts and means. Do thou take therefore, the help of act!"' "Sanjaya continued, 'Thus addressed by Vasudeva, Pandu's son of rigid vows, smiling the while, addressed, O monarch, thy son of great might, who, O Bharata, was then within the waters of that lake, saying, "Why, O Suyodhana, hast thou entered these waters, after having caused all the Kshatriyas to perish and after having, O king, caused thy own race to be annihilated? Why hast thou entered into this lake today, wishing to save thy own life? Arise, O king, and fight us, O Suyodhana! Where, O foremost of men, hath that pride and that sense of honour which thou hadst now gone, since, O king, thou hast enchanted these waters and art now lying within them? All men speak of thee in assemblies as a hero.
