Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
सूर्यो ऽमरत्वममृते त्रयस् त्रिषु नियच्छति एवं रश्मिसहस्रं तु सौरं लोकार्थसाधकम् //
sūryo 'maratvamamṛte trayas triṣu niyacchati evaṃ raśmisahasraṃ tu sauraṃ lokārthasādhakam //
The Sun, through amṛta, the nectar of immortality, regulates the three (vital principles) in the three (worlds). Thus the solar host of a thousand rays accomplishes the welfare and purpose of the worlds.
It highlights the sustaining order of creation: Surya’s rays regulate life across the three worlds; by implication, when this regulation withdraws, cosmic stability fails—an idea that underlies Pralaya motifs.
It models governance: as the Sun regulates without partiality for the welfare of all worlds, a king/householder should practice steady, impartial discipline and life-supporting stewardship (protection, provisioning, and order).
Ritually, it supports Surya-upasana and solar timing (daily rites aligned to sunlight). Architecturally, it implies the importance of solar orientation and light in sacred planning—an idea often leveraged in Matsya Purana–style temple and ritual space considerations.
