Matsya Purana — Paurava Genealogy
दिवोदासस्य दायादो धर्मिष्ठो मित्रयुर्नृपः मैत्रायणावरः सो ऽथ मैत्रेयस्तु ततः स्मृतः //
divodāsasya dāyādo dharmiṣṭho mitrayurnṛpaḥ maitrāyaṇāvaraḥ so 'tha maitreyastu tataḥ smṛtaḥ //
Divodāsa’s heir was the most righteous king Mitrayu. He was also known as Maitrāyaṇāvara; and from him, the one remembered thereafter was called Maitreya.
This verse does not discuss pralaya; it preserves a dynastic succession, emphasizing continuity of royal lineages through remembered names and epithets.
By calling Mitrayu “dharmiṣṭha” (most righteous), the verse highlights dharma as the defining virtue of kingship—implying that legitimate succession is ideally marked by adherence to righteous rule.
No Vāstu or ritual procedure is stated here; the verse is genealogical, useful mainly for tracing Puranic royal lineages rather than temple architecture rules.
