Svargārohaṇa-parva Adhyāya 5 — Karmaphala-Nirdeśa and Phalāśruti (कर्मफलनिर्देशः फलश्रुतिश्च)
भरतानां महज्जन्म तस्माद् भारतमुच्यते । महत्त्वाद् भारवत्त्वाच्च महाभारतमुच्यते । निरुक्तमस्य यो वेद सर्वपापै: प्रमुच्यते
bharatānāṃ mahaj janma tasmād bhāratam ucyate | mahattvād bhāravattvāc ca mahābhāratam ucyate | niruktam asya yo veda sarvapāpaiḥ pramucyate |
Dijo Vaiśampāyana: «Porque relata el gran nacimiento y las hazañas de los descendientes de Bharata, se llama Bhārata. Y porque es inmenso en grandeza y de peso en sustancia, se llama Mahābhārata. Quien conoce de veras este sentido etimológico de la obra queda liberado de todos los pecados».
वैशम्पायन उवाच
The verse teaches that the epic’s very name encodes its purpose and authority: it narrates the exalted lineage and deeds of the Bharatas, and it is ‘great’ and ‘weighty’ in meaning. Understanding this (not merely reciting it) is presented as spiritually purifying, freeing one from sin.
In Vaiśampāyana’s narration, a brief meta-explanation is given about the title of the text itself—why it is called Bhārata and Mahābhārata—and the religious merit attributed to knowing this derivation.
