Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
सशैवालं तथान्यैर्वा दोषैर्दुष्टं विवर्जयेत् च्लेअनिन्ग् ओफ़् च्लोथेस् वस्त्रशौचान्वितः कुर्यात् सर्वकार्याणि वै द्विजाः
saśaivālaṃ tathānyairvā doṣairduṣṭaṃ vivarjayet cleaning of clothes vastraśaucānvitaḥ kuryāt sarvakāryāṇi vai dvijāḥ
藻のような汚れであれ、他の過失であれ、穢れたものはすべて捨て去るべきである。おお二度生まれの者よ、衣の清浄を具え、あらゆる務めと儀礼—とりわけシヴァに関わる行—は、清らかな状態においてのみ行え。
Suta Goswami (narrating Shiva-dharma and śauca rules to the sages of Naimiṣāraṇya)
It establishes śauca—especially clean clothing and avoidance of defiled materials—as a prerequisite for effective Liṅga-pūjā, aligning outer purity with inner devotional focus toward Pati (Śiva).
By insisting on purity before action, it implies that approach to Shiva-tattva requires refinement of the worshipper’s state; the pashu (soul) reduces pasha (impurity/bondage) through disciplined conduct while turning toward Pati.
Ritual śauca (purity) as part of pūjā-vidhi—clean garments and rejection of contaminated items—supporting the Pāśupata-style discipline where external order reinforces inner steadiness.
