Aghora-Mantra Japa: Graded Expiations, Pañcagavya Purification, and Homa for Mahāpātaka-Nivṛtti
चतुर्गुणं बुद्धिपूर्वे क्रोधादष्टगुणं स्मृतम् वीरहा लक्षमात्रेण भ्रूणहा कोटिमभ्यसेत्
caturguṇaṃ buddhipūrve krodhādaṣṭaguṇaṃ smṛtam vīrahā lakṣamātreṇa bhrūṇahā koṭimabhyaset
The expiation is said to be fourfold when a deed is done with prior deliberation; but when it is committed out of anger, it is remembered as eightfold. One who has slain a hero should undertake the prescribed practice to the measure of one hundred thousand; but one who has slain an embryo should undertake it to the measure of ten million.
Suta Goswami (narrating traditional dharma and prāyaścitta standards to the sages of Naimiṣāraṇya)
It frames purification as a prerequisite for approaching Linga-pūjā: the pashu (bound soul) reduces pāśa (bondage of karma) through disciplined expiation, becoming fit for Śiva’s grace (Pati).
Indirectly, it presents Śiva as the purifier and final refuge: while karma binds through intention and anger, purification and restraint prepare the seeker for Śiva’s anugraha (grace) that loosens bondage.
A graded prāyaścitta involving repeated disciplined practice (abhyāsa)—typically tapas, japa, vrata, and Śiva-oriented worship—scaled to the severity and mental cause (deliberation vs anger) of the act.
