Matsya Purana — Marks of Karma-yoga and the Five Great Daily Sacrifices
पञ्च सूना गृहस्थस्य तेन स्वर्गं न गच्छति तत्पापनाशनायामी पञ्च यज्ञाः प्रकीर्तिताः //
pañca sūnā gṛhasthasya tena svargaṃ na gacchati tatpāpanāśanāyāmī pañca yajñāḥ prakīrtitāḥ //
For the householder there are five “slaughter-houses,” sources of unavoidable harm; because of them he does not attain heaven. Therefore, to destroy that sin, the five sacrifices (yajñas) have been proclaimed.
This verse is not about Pralaya; it addresses everyday dharma, explaining that household life involves unavoidable harm and therefore requires daily purificatory sacrifices.
It directly defines gṛhastha-dharma: a householder incurs inevitable demerit through daily activities, and the Matsya Purana prescribes the pañca-mahāyajñas as a corrective discipline to maintain purity and merit.
The significance is ritual: it introduces the pañca-mahāyajñas as expiation for the ‘five sūnāḥ’—a foundational principle behind daily offerings, hospitality, and maintenance of sacred order in household ritual life.
