Matsya Purana — Paurava Genealogy: Bharata
संनिविष्टो ह्य् अहं पूर्वम् इह नाम बृहस्पते अमोघरेताश्च भवान् नावकाश इह द्वयोः //
saṃniviṣṭo hy ahaṃ pūrvam iha nāma bṛhaspate amogharetāśca bhavān nāvakāśa iha dvayoḥ //
“Indeed, O Bṛhaspati, I had already taken my place here earlier; and you too are of unfailing seed. Here there is no room for the two of us (together).”
This verse does not discuss Pralaya directly; it focuses on precedence and incompatibility of two powerful figures sharing the same place, a common motif in rishi narratives rather than cosmic dissolution.
Indirectly, it highlights the ethics of propriety and respecting established precedence—principles a king or householder applies in governance and social order (avoiding rivalry, honoring rightful occupancy, and preventing conflict).
No explicit Vāstu or ritual procedure is stated; however, the phrase ‘no room for two’ can be read as a narrative cue about exclusive ritual/seat entitlement (āsana/adhikāra) rather than temple architecture rules.
