Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
मासौ द्वौ देवताः सूर्ये वसन्ति च शरदृतौ पर्जन्यश्चैव पूषा च भरद्वाजः सगौतमः //
māsau dvau devatāḥ sūrye vasanti ca śaradṛtau parjanyaścaiva pūṣā ca bharadvājaḥ sagautamaḥ //
For the two months of the autumn season (Śarad), the presiding deities are Parjanya and Pūṣan; and the associated seers are Bharadvāja and Gautama.
This verse does not discuss Pralaya; it provides a ritual-cosmological mapping of the autumn season’s two months to their presiding deities and associated ṛṣis.
It supports dharmic timekeeping: kings and householders schedule seasonal rites, offerings, and public ceremonies in harmony with the presiding deities (Parjanya, Pūṣan) and ṛṣi lineages, aligning governance and domestic worship with the sacred calendar.
Ritually, it identifies which deities are especially apt for Śarad-season worship; such calendrical rules are often used to choose auspicious timings (kāla) for consecrations, temple festivals, and seasonal offerings, even when the verse itself is not a direct Vāstu prescription.
