Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
देवतानां पितॄणां च मनुष्याणां च सर्वदा कुर्यादहरहर्यज्ञैर् भूतर्षिगणतर्पणम् //
devatānāṃ pitṝṇāṃ ca manuṣyāṇāṃ ca sarvadā kuryādaharaharyajñair bhūtarṣigaṇatarpaṇam //
One should always, day after day, perform—through daily sacrificial offerings—the acts of satiation (tarpaṇa) for the gods, the forefathers, human beings, and also for the hosts of beings and sages.
This verse does not describe pralaya; it teaches nitya-karma—daily ritual duties that sustain cosmic and social order through offerings to devas, pitṛs, and other recipients.
It frames an everyday obligation: a king or householder should maintain regular yajña-like offerings and tarpaṇa, honoring gods, ancestors, sages, and supporting humans—thus upholding dharma through continual reciprocity.
The significance is ritual (not architectural): it emphasizes tarpaṇa and daily offerings (yajña) as prescribed acts of appeasement/satiation for multiple classes of beings.
