Adhyāya 166: Kṛtaghna-doṣa (कृतघ्नदोषः) — the fault of ingratitude and the limits of expiation
प्राजापत्यमदत्त्वाश्चमग्न्याधेयस्य दक्षिणाम् । अनाहिताग्निरिति स प्रोच्यते धर्मदर्शिभि:
prājāpatyam adattvāś ca agnyādheyasya dakṣiṇām | anāhitāgnir iti sa procyate dharmadarśibhiḥ ||
Bhīṣma said: One who begins the Agnyādhāna rite (the establishment of the sacred fires) but does not give the prescribed priestly fee dedicated to Prajāpati—namely the horse-form dakṣiṇā—is, according to those who truly discern dharma, to be called ‘anāhitāgni’ (one who has not properly established the fires).
भीष्म उवाच
Ritual acts are incomplete without fulfilling their prescribed obligations—especially the proper dakṣiṇā. Merely lighting or commencing the sacred-fire rite does not confer the status of an ‘āhitāgni’ unless the rite is completed in accordance with dharma.
In Bhīṣma’s instruction on dharma in the Śānti Parva, he defines a normative standard: a person who starts Agnyādhāna but withholds the Prajāpati-related dakṣiṇā is judged by dharma-knowers as effectively ‘not having established the fires’ (anāhitāgni).
