Matsya Purana — Genealogy and Classification of Sacred Fires
सहरक्षस्तु वै कामान् गृहे स वसते नृणाम् क्रव्यादग्निः सुतस्तस्य पुरुषान्यो ऽत्ति वै मृतान् //
saharakṣastu vai kāmān gṛhe sa vasate nṛṇām kravyādagniḥ sutastasya puruṣānyo 'tti vai mṛtān //
Along with the rākṣasa-spirit, desires indeed dwell in the houses of men. From him is born the fire called Kravyādāgni, which consumes the bodies of the dead.
It does not describe cosmic pralaya; it describes a micro-level reality of death and the consuming power of fire (Kravyādāgni) in human rites, highlighting mortality within worldly life.
It frames the house as a place where desire (kāma) and harmful influences may co-exist, implying the householder’s duty to regulate desire through dharma and to perform proper funerary rites, acknowledging death’s ritual consequences.
The ritual significance is central: Kravyādāgni denotes the cremation fire that consumes the dead, pointing to antyeṣṭi (funeral rites) and the sacred management of fire in dharmic practice rather than temple architecture.
