What the Mahābhārata is
The Mahābhārata is both epic and encyclopaedia. Its narrative core is the struggle between the five Pāṇḍava brothers (Yudhiṣṭhira, Bhīma, Arjuna, Nakula, Sahadeva) and their cousins the Kauravas (led by Duryodhana) over the kingdom of Hastināpura — a struggle that culminates in the eighteen-day Kurukṣetra war. But around this narrative frame is woven an encyclopaedic treatment of Dharma in all its aspects: political philosophy (rājanīti), ethics, theology, mythology, cosmology, genealogy, and philosophy.
The text opens with its own self-description: yad ihāsti tad anyatra, yan nehāsti na tat kvacit — "What is here is found elsewhere; what is not here is nowhere." Everything worth knowing is said to be contained in it. This claim is not purely rhetorical: the Mahābhārata is the most comprehensive single source for the norms, values, debates, and cosmologies of classical Sanātana Dharma.
The BORI (Bhandarkar Oriental Research Institute, Pune) Critical Edition of the Mahābhārata (1919–1966, 19 volumes) is the scholarly standard — it collated all known manuscripts to establish the best available text. The Critical Edition significantly differs from the "vulgate" (Kumbhakonam) text that had been used previously, removing a substantial amount of later interpolation.

The BORI Critical Edition — textual scholarship
The Bhandarkar Oriental Research Institute Critical Edition (Pune, 1919–1966; 19 vols.) is the essential scholarly text of the Mahābhārata. It collated manuscripts from across India to establish what can most reliably be attributed to the core tradition, removing significant later interpolations found in the "vulgate" printed editions. The Critical Edition is c.15% shorter than the vulgate. Hiltebeitel's Dharma (OUP, 2011) is a comprehensive scholarly study of the Mahābhārata's Dharma teaching based primarily on the Critical Edition.
