Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
संध्यालोपे कृते विप्रः त्रिरावृत्त्यैव शुध्यति आह्निकच्छेदने जाते शतमेकमुदाहृतम्
saṃdhyālope kṛte vipraḥ trirāvṛttyaiva śudhyati āhnikacchedane jāte śatamekamudāhṛtam
若婆罗门怠慢暮晨礼(Sandhyā),以三遍重行即可得净。若日常必行之仪(āhnika)已断缺,则规定以一百遍为赎净之法。
Suta Goswami (narrating dharma and prāyaścitta norms within the Linga Purana discourse)
It sets a purity-standard: regular Sandhyā and āhnika maintain adhikāra (fitness) for Shiva-upāsanā and Linga-pūjā; lapses create mala (impurity) that must be removed through prescribed repetition.
Implicitly, Shiva is Pati—the Lord approached through disciplined purification. By correcting omissions, the pashu (bound soul) loosens pasha (bondage) and becomes fit for Shaiva sādhana oriented to Shiva-tattva.
Prāyaścitta by āvṛtti (repetition/recitation) for Sandhyā-vandana and daily āhnika—showing that regulated nitya-karma supports inner steadiness required for Pāśupata-oriented practice.
