Vaiśampāyana said: Endowed with spiritual majesty, established in Sāṅkhya and Yoga, and awakened to many branches of sacred learning, the sage Vyāsa—seeing with divine vision—composed this history so that the fame of the great-souled Pāṇḍavas and of other radiant kings rich in wealth might be spread abroad. The work is thus presented as a dharma-grounded record, authored by one who knows the ordinances of right conduct and whose inner being is purified by ascetic power.
वैशम्पायन उवाच
The verse frames the Mahābhārata as a dharma-oriented sacred history authored by a spiritually accomplished seer. It emphasizes that true authority in transmitting ethical narrative comes from inner purity (tapas), disciplined wisdom (Sāṅkhya-Yoga), and comprehensive learning, so that the exemplary fame (kīrti) of righteous figures may guide later generations.
Vaiśampāyana describes Vyāsa’s qualifications—spiritual power, mastery of Sāṅkhya and Yoga, and multi-śāstra expertise—and states that, using divine sight, Vyāsa composed this history to spread the renown of the Pāṇḍavas and other illustrious kings.
