Matsya Purana — Cosmic Architecture of Sun–Moon and the ‘Houses of the Gods’
क्षेत्राण्येतानि वै सूर्यम् आपतन्ति गभस्तिभिः क्षेत्राणि तेषामादत्ते सूर्यो नक्षत्रता ततः //
kṣetrāṇyetāni vai sūryam āpatanti gabhastibhiḥ kṣetrāṇi teṣāmādatte sūryo nakṣatratā tataḥ //
These (celestial) “fields” indeed reach the Sun by means of his rays; the Sun, taking up those fields, thereby brings about their status as nakṣatras—luminous star-forms.
It is not a pralaya-verse; it presents a cosmological mechanism: the Sun’s rays interact with celestial ‘fields/regions’ and this relation accounts for their nakṣatra-status (their recognizable astral form).
Indirectly, it supports dharmic time-reckoning: nakṣatras are foundational for choosing auspicious timings (muhūrta) for royal consecrations, campaigns, marriages, and household saṃskāras—linking governance and domestic rites to cosmic order.
Ritually, nakṣatra-knowledge guides temple consecration dates, image installation (pratiṣṭhā), and major yajñas; the verse supplies the Purāṇic rationale that nakṣatras derive their operative identity through the Sun’s rays, reinforcing solar–astral timing in ritual planning.
