mārkaṇḍeyasamāsyāyām upākhyānāni sarvaśaḥ | pṛthor vainyasya yatroktam ākhyānaṃ paramarṣiṇā ||
In the course of the dialogue with Mārkaṇḍeya, many subsidiary narratives were recounted in full. Among them, the supreme seer related the celebrated story of Pṛthu, the son of Vena—an episode presented as an instructive example of righteous kingship and the restoration of order.
राम उवाच
The verse frames the Pṛthu–Vena episode as an upākhyāna (illustrative tale) within a sage’s discourse, implying that exemplary stories of rulers are used to teach dharma—especially the duties of kingship, the correction of disorder, and governance oriented toward the welfare of the world.
During a dialogue with the sage Mārkaṇḍeya, numerous instructive sub-stories are narrated. One of these is the account of Pṛthu, identified as Vena’s son (Vainya), which is introduced here as part of the larger sequence of teachings and exempla.
