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.
