Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
ब्रह्मोपेतश्च वै रक्षो यज्ञोपेतस्तथैव च इत्येते निवसन्ति स्म द्वौ द्वौ मासौ दिवाकरे //
brahmopetaśca vai rakṣo yajñopetastathaiva ca ityete nivasanti sma dvau dvau māsau divākare //
Thus, the Rakṣa named Brahmopeta and likewise the Rakṣa named Yajñopeta reside in association with the Sun, two months each.
This verse does not describe Pralaya; it outlines a calendrical-cosmic arrangement in which specific Rakṣas are assigned to the Sun’s course for fixed two-month periods.
By linking named beings to the Sun’s monthly cycle, the text supports time-keeping for dharmic life—helping householders and rulers schedule yajñas, vows, donations, and public rites according to an ordered sacred calendar.
The significance is primarily ritual rather than architectural: it reflects a Saura/Jyotiṣa framework used to align ceremonies with solar months and their associated attendants, reinforcing correct timing (kāla) as a key component of ritual efficacy.
