Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
यस्मात्त्वं सर्वयज्ञानाम् अङ्गत्वेन व्यवस्थितः यानं विभावसोर्नित्यम् अतः शान्तिं प्रयच्छ मे //
yasmāttvaṃ sarvayajñānām aṅgatvena vyavasthitaḥ yānaṃ vibhāvasornityam ataḥ śāntiṃ prayaccha me //
Since you are established as an integral limb of all sacrifices, and are ever the vehicle of Vibhāvasu (Agni), therefore grant me peace.
It does not directly discuss Pralaya; it emphasizes ritual cosmology where Agni (Vibhāvasu) is indispensable to yajña, and peace (śānti) is sought through sacred order rather than flood/dissolution narrative.
For householders and kings who sponsor sacrifices, it underscores that yajña depends on Agni and its proper auxiliaries; seeking śānti aligns with dharmic governance and domestic rites aimed at stability, prosperity, and the removal of obstacles.
Ritually, it frames Agni as an aṅga (core component) of all yajñas and invokes śānti—useful as a śānti-pāṭha style prayer before/after homa; it does not specify Vāstu rules but supports the ritual foundation often performed in consecrations.
