Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
पञ्चैते विहिता यज्ञाः पञ्चसूनापनुत्तये कण्डनी पेषणी चुल्ली जलकुम्भी प्रमार्जनी //
pañcaite vihitā yajñāḥ pañcasūnāpanuttaye kaṇḍanī peṣaṇī cullī jalakumbhī pramārjanī //
These five sacrifices (yajñas) are prescribed to ward off the five “household harms”: the pounding-stone, the grinding-stone, the hearth, the water-pot, and the broom—namely, the acts of pounding, grinding, cooking, drawing water, and sweeping, which unavoidably injure minute beings.
It does not describe pralaya; it focuses on dharma in ordinary life, emphasizing that even routine household acts can unintentionally harm living beings and therefore require daily expiatory-sacrificial discipline.
It directly guides the householder: one should perform the prescribed five daily sacrifices as a moral remedy for unavoidable violence involved in cooking, grinding, cleaning, and water-drawing—reinforcing ahiṃsā and responsibility in daily living (a model also upheld by righteous kings).
The significance is ritual rather than architectural: it identifies the five domestic sources of unintentional harm (pañca-sūnā) and links them to the need for pañca‑yajña—regular rites that purify daily life and uphold dharmic order.
