Matsya Purana — Mahāgaurī’s Entry
*सूत उवाच शिरसा तु ततो वन्द्य मातरं पूर्णमानसः उवाचोदितपूर्णेन्दुद्युतिं च हिमशैलजाम् //
*sūta uvāca śirasā tu tato vandya mātaraṃ pūrṇamānasaḥ uvācoditapūrṇendudyutiṃ ca himaśailajām //
Sūta said: Then, bowing his head, he reverently saluted the Mother with a heart made whole, and addressed Himāśailajā—she whose radiance was like the newly risen full moon.
This verse is devotional and dialogic, focusing on reverent salutation to Devī (Himāśailajā); it does not directly describe Pralaya, but it reflects the Purāṇic method of beginning sacred instruction with auspicious praise and surrender.
It models proper conduct (ācāra): approaching a revered deity or teacher with humility (head bowed) and a composed mind—an ideal applicable to household worship, vows, and righteous leadership grounded in reverence and self-restraint.
No Vāstu or temple-measurement rule is stated here; the ritual takeaway is the etiquette of invocation—offering pranāma and addressing the deity with honorific epithets before requesting boons or teachings.
