Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
सोमः सूर्यो बुधश्चैव भार्गवश्चेति शीघ्रगाः यावन्ति चैव ऋक्षाणि कोट्यस्तावन्ति तारकाः //
somaḥ sūryo budhaścaiva bhārgavaśceti śīghragāḥ yāvanti caiva ṛkṣāṇi koṭyastāvanti tārakāḥ //
Soma (the Moon), the Sun, Budha (Mercury), and Bhārgava (Venus) are the swift-moving celestial bodies. And as many as the constellations (ṛkṣas) are, so many crores (koṭis) of stars (tārakās) there are.
This verse is not describing Pralaya; it belongs to a cosmological-astronomical listing, emphasizing the ordered structure of the heavens (planets, constellations, and vast numbers of stars).
Indirectly, it supports dharma through timekeeping: knowledge of grahas and nakṣatras underlies calendrics for rites, auspicious timings, and governance decisions—key practical supports for royal and household ritual order.
Ritually, graha–nakṣatra knowledge informs muhūrta selection for consecrations and ceremonies; architecturally, it can guide auspicious timing for temple building and prāṇa-pratiṣṭhā, though no specific Vāstu rule is stated in this verse.
