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
男子において、葬送儀礼に関わるサピンダ(sapinda)の親縁は第七代で尽きる。さらに十日が過ぎれば、不浄は三夜のみとなる。かくしてアーシャウチャ(āśauca)の規定は、パシュ(paśu・束縛された魂)のために整えられ、正しく清めたのち、シヴァへと向かう行い—規律ある儀礼によってパティ(Pati)を礼拝する道—へ帰らしめる。
Suta Goswami (narrating normative dharma within the Linga Purana discourse to the sages of Naimisharanya)
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).
