Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
सपिण्डता च पुरुषे सप्तमे विनिवर्तते अतिक्रान्ते दशाहे तु त्रिरात्रमशुचिर्भवेत्
sapiṇḍatā ca puruṣe saptame vinivartate atikrānte daśāhe tu trirātramaśucirbhavet
पुरुषे सपिण्डता सप्तमे वंशे विनिवर्तते। दशाहेऽतिक्रान्ते तु त्रिरात्रमशुचिर्भवेत्। एवं पशोः अśauca-नियमः, शुद्ध्या पश्चात् शिवोन्मुखाचाराय—पतिपूजनाय—प्रवृत्त्यर्थम्।

It sets eligibility boundaries for ritual purity: once the prescribed aśauca period is completed, the devotee can resume linga-puja, japa, and śaiva observances without violating dharma.
Indirectly, it frames Shiva as Pati—the ever-pure Lord—while the pashu must follow purification rules to approach His worship; purity disciplines the soul’s conduct toward liberation.
Ritual discipline (aśauca-niyama) connected to death-rites and purification, which safeguards the continuity of Shiva-puja and supports steadiness in sādhana (including Pashupata-aligned practice).
