Matsya Purana — Pṛthu
पृथुर् अप्यवदद् वाक्यम् ईप्सितं देहि सुव्रते सर्वस्य जगतः शीघ्रं स्थावरस्य चरस्य च //
pṛthur apyavadad vākyam īpsitaṃ dehi suvrate sarvasya jagataḥ śīghraṃ sthāvarasya carasya ca //
Pṛthu too spoke these words: “O virtuous one, quickly grant what is desired—for the sake of the entire world, of all that is stationary and all that moves.”
This verse is not about Pralaya; it emphasizes immediate welfare and sustenance for the living world—both immobile and mobile beings—through the granting of a boon.
It reflects Rajadharma: the king’s duty is to seek and secure resources that benefit all beings, prioritizing swift action for universal well-being rather than private gain.
No direct Vastu or ritual procedure is specified; the key takeaway is the governance principle of ensuring prosperity for the entire realm, which later supports rites, temples, and public works.
