bharadvāja uvāca | prajā brāhmaṇasaṃskārāḥ svakarmakṛtaniścayāḥ | ṛṣibhiḥ svena tapasā sṛjyante cāpare paraiḥ ||

Bharadvāja said: “Some peoples were brought forth by the seers through the power of their own austerity—endowed with Brahmanical (Vedic) sacraments and firmly resolved in the performance of their proper duties. Thus, by the ancient sages, further generations of sages and communities continued to be produced.”

Educational Q&A

The verse links social and ethical stability to two forces: (1) saṃskāra—Vedic formation through rites and disciplined education—and (2) niścaya—steadfast commitment to one’s own dharma (sva-karma). It also presents tapas as a creative, world-sustaining power in the hands of ṛṣis.

Bharadvāja describes how sages, through their austerities, generated communities (and successive lines of sages/people) characterized by Vedic refinement and firm adherence to duty, indicating an ongoing transmission from earlier ṛṣis to later ones.
