Mbh 7.93.5a

“Sanjaya said, ‘Having said these words, Drona, that foremost of persons conversant with Brahma, touching water, and duly uttering certain Mantras, speedily tied that highly wonderful and bright armour on Duryodhana’s body for the victory of thy son in that dreadful battle and causing (by that act) all persons there to be filled with amazement. And Drona said, “Let the Vedas, and Brahman, and the Brahmanas, bless thee. Let all the higher classes of reptiles be a source of blessings to thee, O Bharata! Let Yayati and Nahusha, and Dhundhumara, and Bhagiratha, and the other royal sages, all do what is beneficial to thee. Let blessings be to thee from creatures having but one leg, and from those that have many legs. Let blessings be to thee, in this great battle from creatures that have no legs. Let Swaha, and Swadha, and Sachi, also, all do what is beneficial to thee. O sinless one, let Lakshmi and Arundhati too do what is beneficial to thee. Let Asita, and Devala and Viswamitra, and Angiras, and Vasishtha, and Kasyapa, O king, do what is beneficial to thee. Let Dhatri, and the lord of the worlds and the points of the compass and the regents of those points, and the six-faced Karttikeya, all give thee what is beneficial. Let the divine Vivaswat benefit thee completely. Let the four elephants, of the four quarters, the earth, the firmament, the planets, and he who is underneath the earth and holds her (on his head), O king, viz., Sesha, that foremost of snakes, give thee what is for thy benefit. O son of Gandhari, formerly the Asura named Vritra, displaying his prowess in battle, had defeated the best of celestials in battle. The latter, numbering thousands upon thousands, with mangled bodies, those denizens of heaven, with Indra at their head, deprived of energy and might, all repaired to Brahman and sought his protection, afraid of the great Asura Vritra.
