This work sets forth, in full, the ordinances of duty for the four social orders, and also the complete essential purport of the Purāṇas. It further explains the nature, disciplines, and fruits of austerity and celibate studentship, and describes the measures and standards relating to the earth, the moon, and the sun—thus presenting a comprehensive map of dharma, sacred tradition, and cosmic order.
The verse highlights the Mahābhārata’s encyclopedic intent: it teaches dharma by laying out duties for the four varṇas, clarifying the essence of Purāṇic tradition, and explaining disciplines like tapas and brahmacarya, all within a vision of an ordered cosmos.
In the opening of the Ādi Parva, the text is being presented as a comprehensive compendium. This verse continues the catalogue of subjects covered, emphasizing social-ethical prescriptions and spiritual disciplines alongside cosmological knowledge.
