Matsya Purana — The Attendant Hosts of the Sun and Moon: Monthly Gaṇas
*सूत उवाच स रथो ऽधिष्ठितो देवैर् मासि मासि यथाक्रमम् ततो वहत्यथादित्यं बहुभिर् ऋषिभिः सह //
*sūta uvāca sa ratho 'dhiṣṭhito devair māsi māsi yathākramam tato vahatyathādityaṃ bahubhir ṛṣibhiḥ saha //
Sūta said: That chariot is presided over by the gods, month after month, in due order; thereafter it bears along Āditya (the Sun), accompanied by many Ṛṣis.
It does not describe Pralaya directly; it emphasizes the regulated cosmic order of time—month-by-month governance of the Sun’s course by Devas and Ṛṣis—implying stability and maintenance (sthiti) rather than dissolution.
By framing time as divinely ordered, it supports dharmic living tied to the calendar—kings and householders should align rites, donations, vows, and governance with the proper monthly/seasonal sequence maintained by sacred authority.
While not giving Vāstu rules, it underpins ritual timing: Surya-related worship, monthly observances, and temple calendrics depend on the Sun’s ordered course—useful for planning festival cycles and consecration schedules in Puranic practice.
