Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
चारो वातश्च द्वावेतौ यातुधानावुभौ स्मृतौ वसन्त्येते च वै सूर्ये मासयोश्च त्विषोर्जयोः //
cāro vātaśca dvāvetau yātudhānāvubhau smṛtau vasantyete ca vai sūrye māsayośca tviṣorjayoḥ //
Cāra and Vāta—these two are remembered as a pair of Yātudhānas. They are said to abide in the Sun, presiding over the two months and over the victory of brilliance (radiance).
It does not describe Pralaya directly; it classifies beings who ‘abide in the Sun,’ reflecting the Purāṇic idea that cosmic order is maintained through designated solar attendants across the cycle of months and radiance.
Indirectly, it supports the Purāṇic worldview behind calendrical and solar observances: kings and householders time rites, donations, and vows by months and solar power, acknowledging the Sun as the regulator of worldly vitality and success.
Ritually, it aligns with Sūrya-upāsanā and month-based vrata/saṃskāra timing; while not a Vāstu rule, it underpins temple/ritual calendars where solar months and the Sun’s ‘radiance’ govern auspicious scheduling.
