Adhyāya 189: Japa—Inquiry into the Jāpaka, Method
Vidhi), and Fruit (Phala
गोभ्यो वृत्ति समास्थाय पीता: कृष्युपजीविन: । स्वधर्मान् नानुतिष्ठन्ति ते द्विजा वैश्यतां गता:
gobhyo vṛttiṃ samāsthāya pītāḥ kṛṣyupajīvinaḥ | svadharmān nānutiṣṭhanti te dvijā vaiśyatāṃ gatāḥ ||
Dijo Bharadvāja: Aquellos nacidos dos veces que tomaron por sustento el ganado y la agricultura—hasta palidecer su tez—y que ya no practicaron los deberes brahmánicos prescritos para ellos, esos brahmanes, en verdad, asumieron la condición de vaiśyas.
भरद्वाज उवाच
The verse teaches that varṇa-identity is tied to the performance of one’s prescribed dharma and customary livelihood: when a Brahmin abandons Brahminical duties and lives by cattle-rearing and agriculture, he is described as having entered the condition of a Vaiśya.
Bharadvāja is explaining a principle of social-ethical classification within the Śānti Parva’s discussions: he cites how certain twice-born, by adopting pastoral/agricultural livelihood and neglecting their own dharma, came to be regarded as Vaiśyas.
