Matsya Purana — Account of the Manvantaras: Manus
भविष्या दश सावर्णेर् मनोः पुत्राः प्रकीर्तिताः रौच्यादयस्तथान्ये ऽपि मनवः संप्रकीर्तिताः //
bhaviṣyā daśa sāvarṇer manoḥ putrāḥ prakīrtitāḥ raucyādayastathānye 'pi manavaḥ saṃprakīrtitāḥ //
In the future, ten sons of Sāvarṇa Manu are proclaimed—beginning with Raucya; and other Manus too are likewise duly enumerated.
It situates history within cyclic cosmic time: different Manus arise in successive ages (Manvantaras), a framework closely tied to renewals after cosmic dissolutions, though Pralaya is not described directly here.
By emphasizing Manu-lineages, it points to Manu as the archetype of law and governance; kings and householders are implicitly guided to align conduct with Manu-based dharma traditions preserved across successive Manus.
No direct Vāstu or ritual procedure is stated; the verse is primarily genealogical, serving as a doctrinal anchor for later dharma/ritual prescriptions traced to Manu traditions.
