Matsya Purana — Genealogy and Classification of Sacred Fires
पूर्वे मन्वन्तरे ऽतीते शुक्रैर्यामैश्च तैः सह एते देवगणैः सार्धं प्रथमस्यान्तरे मनोः //
pūrve manvantare 'tīte śukrairyāmaiśca taiḥ saha ete devagaṇaiḥ sārdhaṃ prathamasyāntare manoḥ //
When the earlier Manvantara had passed, together with the Śukras and the Yāmas, these very groups of gods existed in the Manvantara of the first Manu as well.
It implies cyclical cosmic administration: after one Manvantara ends, similar classes of divine hosts (deva-gaṇas like the Śukras and Yāmas) are described as present again in another Manvantara, reflecting continuity across cosmic cycles rather than a one-time creation.
Indirectly, it frames dharma within cosmic order: kings and householders are expected to align conduct with the governing order of their age (Manvantara). The verse supports the Purāṇic idea that social and religious duties are stabilized by recurring divine oversight.
No direct Vāstu or temple-rule detail appears here; the ritual takeaway is contextual—Manvantara-based cosmology is often used to situate rites, genealogies, and sacred histories within an authoritative timeline in the Matsya Purana.
