Matsya Purana — Paurava Genealogy
यं यं कराभ्यां स्पृशति जीर्णं रोगिणमेव च पुनर्युवा च भवति तस्मात्तं शंतनुं विदुः //
yaṃ yaṃ karābhyāṃ spṛśati jīrṇaṃ rogiṇameva ca punaryuvā ca bhavati tasmāttaṃ śaṃtanuṃ viduḥ //
Whomever he touches with his hands—even one who is aged or diseased—becomes youthful again; therefore, he is known as Śaṃtanu.
This verse does not discuss pralaya; it praises a king’s extraordinary, restorative power, presented within a dynastic narrative.
It frames ideal kingship as protective and life-sustaining: the ruler is portrayed as one who removes affliction and restores well-being—an amplified, poetic expression of the king’s duty to heal social and physical distress.
No Vāstu, temple-building, or ritual procedure is mentioned in this verse; its focus is on royal epithet and beneficent power.
