Mbh 5.161.10b

Let thy anger, thy might and prowess, and knowledge, and thy lightness of hand in the use of weapons, be exhibited! Fight, O son of Pritha, and prove to be a man! The incantations in respect of all thy weapons have been performed. The field of Kurukshetra is free from mire. Thy steeds are hale and strong. Thy soldiers have received their pay. With Kesava, therefore, as (thy) second, fight (with us)! Without encountering Bhishma as yet, why dost thou indulge in such boasts? Like a fool, who, without having ascended the Gandhamadana mountains, boasts (of his would-be feat), thou, O son of Kunti, art indulging in a similar bragging, be a man! Without having vanquished in battle the invincible Karna of the Suta race, or Salya, that foremost of persons, or Drona, the first of all mighty warriors and equal unto the lord of Sachi in battle, how canst thou, O Partha, covet for thy kingdom? He that is a preceptor of both Vedic lore and bowmanship, he that hath crossed both those branches of learning, he that is foremost in battle and imperturbable (as a tower), he whose might knoweth no diminution, that commander of armies, Drona of great effulgence,--him, O Partha, thou wishest in vain to conquer! It is never heard that the Sumeru peak hath been crushed by the wind. Yet even the wind will bear away Sumeru, heaven itself will fall down on the earth, the very Yugas will be altered in respect of their course, if what thou hast said unto me becometh true! What man is there, desirous of life, be it Partha or any body else, who having approached that grinder of foes, would be able to return home with sound body? What person is there, treading upon the earth with his feet, who, encountered by Drona and Bhishma and struck with their arrows, would escape from the battle with life?
