Matsya Purana — Agastya’s Origin
सप्तैव लोकानाप्नोति सप्तार्घान् यः प्रयच्छति यावदायुश्च यः कुर्यात् परं ब्रह्माधिगच्छति //
saptaiva lokānāpnoti saptārghān yaḥ prayacchati yāvadāyuśca yaḥ kuryāt paraṃ brahmādhigacchati //
He who offers arghya seven times attains the seven worlds; and he who performs it throughout his lifespan ultimately reaches the Supreme Brahman.
This verse does not describe pralaya directly; it emphasizes a dharmic ritual (arghya) whose merit spans the cosmic hierarchy of the seven worlds, implying a universe structured in multiple lokas rather than focusing on dissolution.
It frames arghya as a lifelong discipline: a householder (and by extension a king as chief householder) should sustain daily reverential offerings, gaining worldly merit (loka-attainment) and ultimately spiritual liberation (Brahman-realization).
Ritually, it highlights the potency of repeated arghya—formal water offering with reverence—often performed to deities, sages, or the Sun; no Vastu or temple-construction rule is stated, but it supports the broader Matsya Purana ritual framework used alongside temple worship.
