Aghora-Mantra Japa: Graded Expiations, Pañcagavya Purification, and Homa for Mahāpātaka-Nivṛtti
कायिकानि सुमिश्राणि तथा प्रासंगिकानि च बुद्धिपूर्वं कृतान्येव सहजागन्तुकानि च
kāyikāni sumiśrāṇi tathā prāsaṃgikāni ca buddhipūrvaṃ kṛtānyeva sahajāgantukāni ca
Actions are of many kinds: bodily acts; those that are mixed in motive and outcome; those that arise incidentally from circumstance; those performed deliberately with prior intention; and those that are innate or that arise adventitiously. Knowing these distinctions, the paśu (bound soul) discerns the workings of pāśa and turns its agency toward the Lord (Pati), Śiva.
Suta Goswami
It trains the devotee to examine actions by intention and origin; such karma-viveka purifies conduct, making Linga-puja a means to loosen pāśa (bondage) and align the paśu (soul) with Pati (Śiva).
Śiva-tattva is implied as Pati—the witnessing Lord beyond the changing categories of action—toward whom disciplined agency and purified intention are directed for liberation.
The implied practice is self-audit (viveka) central to Pāśupata discipline: recognizing deliberate, habitual, incidental, and mixed actions so they can be offered in worship and restrained through yogic observance.
