karma śūdre kṛṣir vaiśye saṅgrāmaḥ kṣatriye smṛtaḥ | brahmacaryaṁ tapo mantrāḥ satyaṁ ca brāhmaṇe sadā ||
Service and labor are prescribed as the work of the Śūdra; agriculture (and trade) are the livelihood of the Vaiśya; and battle is remembered as the duty of the Kṣatriya. For the Brāhmaṇa, however, the constant disciplines are brahmacarya, austerity, sacred recitation (and Vedic study), and truthfulness.

The verse outlines varṇa-based duties and virtues: each social role has its prescribed work, while the Brāhmaṇa is especially bound to disciplines like brahmacarya, tapas, mantra-recitation, and unwavering truthfulness—presenting dharma as both outer responsibility and inner moral restraint.
In the Vana Parva’s dialogue context, the hunter (Vyādha) instructs a listener on dharma, using a traditional classification of duties to emphasize that righteousness is maintained by faithfully performing one’s role and cultivating virtues such as truth.
