Matsya Purana — Account of the Manvantaras: Manus
पञ्चमस्य मनोस् तद्वद् रैवतस्यान्तरं शृणु देवबाहुः सुबाहुश्च पर्जन्यः सोमपो मुनिः //
pañcamasya manos tadvad raivatasyāntaraṃ śṛṇu devabāhuḥ subāhuśca parjanyaḥ somapo muniḥ //
In the same manner, listen to the interval (Manvantara) of the fifth Manu, Raivata: there were Devabāhu, Subāhu, Parjanya, Somapa, and the sage Muni.
This verse does not describe Pralaya directly; it maps cosmic time by naming the fifth Manvantara (Raivata) and key figures associated with that era, which is part of the Purana’s creation-era chronology.
Indirectly: by organizing history into Manvantaras and naming exemplary rulers/sages, the text frames dharma as something preserved through lineages and eras—useful for kings and householders seeking models of righteous governance and conduct.
No Vastu Shastra, temple architecture, or ritual procedure is stated in this verse; it is a genealogical/chronological notice within the Manvantara narration.
