Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
शतानि पञ्च चत्वारि त्रीणि द्वे चैकमेव च सर्वोपरि निसृष्टानि मण्डलानि तु तारकाः //
śatāni pañca catvāri trīṇi dve caikameva ca sarvopari nisṛṣṭāni maṇḍalāni tu tārakāḥ //
At the very highest level the stellar spheres were fashioned: five hundreds, four hundreds, three hundreds, two hundreds, and one hundred—altogether, the circular regions of the stars.
It speaks to sarga (creation/emanation): the topmost stellar regions (tārakā-maṇḍalas) are described as having been “nisṛṣṭāni” (produced), emphasizing cosmic ordering rather than dissolution.
Indirectly, it supports the Purāṇic ideal that rulers and householders should align conduct and ritual timing with cosmic order—using knowledge of celestial cycles (stars/maṇḍalas) for calendrical and ceremonial correctness.
No direct Vāstu rule is stated, but the idea of maṇḍala (ordered ‘circles/diagrams’) resonates with ritual and temple planning: sacred layouts often mirror cosmic stratification, a common Matsya Purana theme used in Puranic temple architecture rules.
