Mbh 13.35.1b

[263] Endued with faith that is fraught with compassion towards all creatures, and devoted to self-restraint and the study of the Vedas, ye shall attain to the fruition of all your wishes. Whatever things exist in the world of men, whatever things occur in the region of the deities, can all be achieved and acquired with the aid of penances and knowledge and the observance of vows and restraints.' I have thus recited to thee, O sinless one, the verses that were sung by Brahma himself. Endued with supreme intelligence and wisdom, the Creator himself ordained this, through compassion for the Brahmanas. The puissance of those among them that are devoted to penances is equal to the might of kings. They are verily irresistible, fierce, possessed of the speed of lightning, and exceedingly quick in what they do. There are amongst them those that are possessed of the might of lions and those that are possessed of the might of tigers. Some of them are endued with the might of boars, some with that of the deer, and some with that of crocodiles. Some there are amongst them whose touch resembles that of snakes of virulent poison, and some whose bite resembles that of sharks. Some amongst them are capable of compassing by speech alone the destruction of those that are opposed to them; and some are competent to destroy by a glance only of their eyes. Some amongst them, as already said, are like snakes of virulent poison, and some of them are possessed of very mild dispositions. The dispositions, O Yudhisthira, of the Brahmanas, are of diverse kinds. The Mekalas, the Dravidas, the Lathas, the Paundras, the Konwasiras, the Saundikas, the Daradas, the Darvas, the Chauras, the Savaras, the Varvaras, the Kiratas, the Yavanas, and numerous other tribes of Kshatriyas, have become degraded into the status of Sudras through the wrath of Brahmanas. In consequence of having disregarded the Brahmanas, the Asuras have been obliged to take refuge in the depths of the ocean.
