Matsya Purana — Sādhāraṇa Śrāddha: General Ancestral Rite
निवृत्य प्रणिपत्याथ पर्युक्ष्याग्निं समन्त्रवत् वैश्वदेवं प्रकुर्वीत नैत्यकं बलिमेव च //
nivṛtya praṇipatyātha paryukṣyāgniṃ samantravat vaiśvadevaṃ prakurvīta naityakaṃ balimeva ca //
Having returned, one should bow down; then, after ritually sprinkling water around the sacred fire with the proper mantras, one should perform the Vaiśvadeva offering and also the prescribed daily bali-offering.
This verse is not about pralaya; it focuses on nitya-karma (daily dharma), prescribing fire-related ritual steps and offerings that sustain cosmic order (ṛta) through regular worship.
It outlines a householder-style daily discipline: bowing, maintaining the sacred fire, performing Vaiśvadeva, and giving bali. In the Matsya Purana’s ethical framework, even rulers are expected to uphold such regular rites (personally or through proper delegation) as part of protecting dharma.
Ritually, it specifies paryukṣa (sprinkling around the fire) and the Vaiśvadeva and bali offerings—core domestic/ritual-fire procedures. Architecturally, it indirectly implies a properly maintained sacred-fire space (agni-sthāna) within the household setting.
