Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
शनैश्चरो विरूपश्च संज्ञापुत्रो विवस्वतः अग्निर्विकेश्यां जज्ञे तु युवासौ लोहिताधिपः //
śanaiścaro virūpaśca saṃjñāputro vivasvataḥ agnirvikeśyāṃ jajñe tu yuvāsau lohitādhipaḥ //
From Vivasvān and Saṃjñā was born Śanaiścara (Saturn), Saṃjñā’s son, of unusual form. And from Agni and Vikeśyā was born the youthful lord of Rohita (the Rohita line or realm).
This verse is not about Pralaya; it belongs to a genealogical register, listing divine/semidivine births (Śani from Vivasvān–Saṃjñā and another figure from Agni–Vikeśyā).
Indirectly, it supports the Purāṇic framework of dynastic legitimacy: kingship and social duties are grounded in remembered lineages and sanctioned origins, which the Matsya Purana often uses to contextualize dharma and rulership.
No Vāstu/temple-rule is stated here; the verse functions as a lineage note. Its ritual relevance is mainly genealogical—invoked in Purāṇic recitations that preserve sacred family lines and deity-descents.
