Mbh 5.161.3

“‘“Thou must also say unto Vasudeva in the presence of the Pandavas these words,--For thy own sake, as also for the sake of the Pandavas, withstand me in battle to the best of thy power! Assuming once more that form which thou hadst assumed before in the Kuru court, rush thou with Arjuna against me (on the field)! A conjuror’s tricks or illusions may (sometimes) inspire fright. But as regards the person that stands armed for fight, such deceptions (instead of inspiring fight) only provoke anger! We also are competent, by our powers of illusion, to ascend to heaven or the firmament, or penetrate into the nether region, or the city of Indra! We also can display various forms in our own body! The great Ordainer bringeth all creatures to subjection by a fiat of His will (and never by such conjuror’s tricks)! Thou always sayest, O thou of Vrishni’s race, these words, viz.,--Causing the sons of Dhritarashtra to be slain in battle, I will confer undisputed sovereignty on the sons of Pritha!--These words of thine were brought to me by Sanjaya. Thou hadst also said, ‘Know, ye Kauravas that it is with Arjuna, having me for his second, ye have provoked hostilities!’ Truthfully adhering to that pledge, put forth thy energy for the Pandavas and fight now in battle to the best of thy power! Show us that thou canst be a man! He is said to be truly alive, who, having ascertained (the might of his) foes inspireth grief in them by resorting to true manliness! Without any reason, O Krishna, great hath been thy fame spread in the world! It will, however, presently be known that there are many persons in the world that are really eunuchs though possessed of the signs of manhood. A slave of Kansa, especially as thou art, a monarch like me should not cover himself in mail against thee!
