Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
वक्रस्तु भार्गवादूर्ध्वं वक्रादूर्ध्वं बृहस्पतिः तस्माच्छनैश्चरश्चोर्ध्वं देवाचार्योपरि स्थितः //
vakrastu bhārgavādūrdhvaṃ vakrādūrdhvaṃ bṛhaspatiḥ tasmācchanaiścaraścordhvaṃ devācāryopari sthitaḥ //
Vakra (a celestial point or planetary node) is placed above Bhārgava (Śukra, Venus). Above Vakra is Bṛhaspati (Jupiter). Above Bṛhaspati stands Śanaiścara (Saturn), situated higher than the divine preceptor.
This verse is not about Pralaya; it outlines a cosmological/astronomical sequence of planetary placements used in Puranic descriptions of the universe.
Indirectly, such graha-order teachings support calendrical and auspicious-time calculations (muhūrta) used by kings and householders for rites, governance decisions, and major life ceremonies.
While not a Vāstu rule itself, the ordering of grahas underpins ritual timing and directional sanctification in temple and domestic rites, informing when and how consecrations and offerings are scheduled.
