Aghora-Mantra Japa: Graded Expiations, Pañcagavya Purification, and Homa for Mahāpātaka-Nivṛtti
उपपातकमप्येवं तथा पापानि सुव्रत मानसानि सुतीक्ष्णानि वाचिकानि पितामह
upapātakamapyevaṃ tathā pāpāni suvrata mānasāni sutīkṣṇāni vācikāni pitāmaha
โอผู้มีพรตอันประเสริฐ ในทำนองเดียวกัน อุปปาตกะและบาปอื่นๆ—ที่กระทำด้วยใจ และที่กระทำด้วยวาจาอันคมกล้า—พึงเข้าใจเช่นนี้ โอปิตามหะ
Suta Goswami (narrating an internal instruction addressed to Brahmā/Pitāmaha)
It broadens purification beyond physical acts: for worthy Linga-pūjā, one must address even upapātakas and subtle sins arising in mind and speech, since these create karmic pasha that obscures devotion to Pati (Śiva).
By implying that liberation requires cleansing subtle faults, it aligns with Śiva-tattva as the pure Pati: the soul (paśu) approaches Śiva through removal of pasha (impurity/karma), including mānasa and vācika doṣas.
Prāyaścitta and inner discipline: restraint of speech (vāk-saṁyama) and purification of mind (citta-śuddhi), which support Pāśupata-oriented practice and readiness for Śiva-pūjā.
