Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
ब्रह्महत्यासहस्राणि भ्रूणहत्यार्बुदानि च कोटिहोमेन नश्यन्ति यथावच्छिवभाषितम् //
brahmahatyāsahasrāṇi bhrūṇahatyārbudāni ca koṭihomena naśyanti yathāvacchivabhāṣitam //
Thousands of sins equal to brahma-hatyā (brahman-slaying) and tens of millions of foeticides are destroyed by performing a koṭi-homa—just as Śiva has declared, fully and in proper measure.
It does not address pralaya; it focuses on prāyaścitta (expiation), asserting that an immense homa can eradicate even the gravest sins.
It supports the dharmic ideal that grievous wrongdoing requires serious ritual atonement; rulers and householders are urged to uphold purity through prescribed expiations and major sacrifices when transgressions occur.
Ritually, it highlights the koṭi-homa—an extraordinarily large-scale fire-offering—as a supreme expiatory act, presented with Śiva’s doctrinal authority.
