Matsya Purana — Yayati’s Fall from Heaven and the Greatness of the Righteous
दृष्ट्वा च त्वाधिष्ठितं देवमार्गे शक्रार्कविष्णुप्रतिमप्रभावम् प्रत्युद्गतास्त्वां वयमद्य सर्वे तस्मात्पाते तव जिज्ञासमानाः //
dṛṣṭvā ca tvādhiṣṭhitaṃ devamārge śakrārkaviṣṇupratimaprabhāvam pratyudgatāstvāṃ vayamadya sarve tasmātpāte tava jijñāsamānāḥ //
Seeing you stationed upon the divine path, radiant with a splendor comparable to Indra, the Sun, and Viṣṇu, we have all come forth today to meet you. Therefore, O Protector, we seek to inquire of you.
It signals the approach to the Pralaya-related teaching: Manu (and companions) recognize a divine protector on the “devamārga” and prepare to question him, a typical prelude to the Flood instruction narrative.
It models dharmic conduct: when encountering divine authority, Manu approaches respectfully and seeks knowledge (jijñāsā). For a king/householder, this implies governance and life-choices should be guided by inquiry into dharma rather than impulse.
No explicit Vāstu or temple rule appears here; the ritual significance is the formal act of approaching and greeting the divine (pratyudgama) and beginning a sanctioned inquiry, which frames later prescriptive teachings in the Purana.
