sarvajñena vidhijñena dharmajñānavatā satā |
atīndriyeṇa śucinā tapasā bhāvitātmanā || 32 ||

I have now told everything that Vaishampayana narrated, at the command of Vyasa, unto the king at his snake sacrifice. Called a history, it is sacred, sanctifying and excellent. It has been composed by the ascetic Krishna, O Brahmana, of truthful speech. He is omniscient, conversant with all ordinances, possessed of a knowledge of all duties, endued with piety, capable of perceiving what is beyond the ken of the senses, pure, having a soul cleansed by penances, possessed of the six high attributes, and devoted to Sankhya Yoga. He has composed this, beholding everything with a celestial eye that has been cleansed (strengthened) by varied lore. He has done this, desiring to spread the fame, throughout the world, of the high-souled Pandavas, as also of other Kshatriyas possessed of abundant wealth of energy.
