Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
कृत्वा च मैथुनं स्पृष्ट्वा पतितं कुक्कुटादिकम् सूकरं चैव काकादि श्वानमुष्ट्रं खरं तथा
kṛtvā ca maithunaṃ spṛṣṭvā patitaṃ kukkuṭādikam sūkaraṃ caiva kākādi śvānamuṣṭraṃ kharaṃ tathā
Selepas melakukan persetubuhan, atau selepas menyentuh orang yang jatuh (tidak suci), atau (akibat bersentuhan dengan) ayam dan seumpamanya, babi, gagak dan seumpamanya, anjing, unta, serta keldai—seseorang menjadi tercemar oleh kenajisan; maka hendaklah ia menjalani disiplin penyucian yang wajar sebelum memulakan pemujaan Śiva dan ibadat Linga-tattva.
Suta Goswami (narrating to the sages of Naimiṣāraṇya, conveying śāstraic rules of purity relevant to Śiva-pūjā)
It sets a śauca (ritual purity) boundary: before approaching the Liṅga for pūjā, one should remove aśauca arising from certain bodily acts and contacts, so the worship is performed with disciplined purity and focused bhakti.
Indirectly, it presents Śiva as Pati—the supremely pure Lord—whose worship calls the pashu (bound soul) to rise above pasha-like impurities through self-regulation, purification, and right conduct.
Śauca and prāyaścitta: maintaining purity through prescribed cleansing/discipline before Śiva-pūjā, aligning the body-mind as a fit vessel for Pāśupata-oriented worship and inner steadiness.
