Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
असंचयाद् द्विजानां च स्नानमात्रेण नान्यथा तथा संनिहितानां च यज्ञार्थं दीक्षितस्य च
asaṃcayād dvijānāṃ ca snānamātreṇa nānyathā tathā saṃnihitānāṃ ca yajñārthaṃ dīkṣitasya ca
二度生まれの祭官(ドヴィジャ)において、不浄が「蓄積しないこと」(すなわち穢れを留めないこと)に由来する場合、清浄は沐浴のみによって成就し、他の方法によらない。同様に、祭儀に臨席する者、ならびに供犠のために灌頂・入戒を受けた者(ディークシタ)にとっても、定められた浄化は沐浴である。
Suta Goswami (narrating the Linga Purana’s ritual regulations to the sages of Naimisharanya)
It sets a practical Shaiva standard of ritual eligibility: for a dīkṣita or officiant engaged in a Shiva-oriented yajña/puja setting, simple bathing is affirmed as the sufficient purifier in this specific impurity-condition, safeguarding uninterrupted worship of Pati (Shiva).
Indirectly, it frames Shiva-tattva as approached through disciplined observance: when external shuddhi is rightly performed, the pashu (soul) becomes fit to turn toward Pati; ritual order supports the loosening of pasha (bondage) by maintaining sanctity in worship.
Snāna (ritual bathing) as a primary act of purification for the dīkṣita and participants in yajña—an external shuddhi that complements inner Shaiva sadhana, aligning the practitioner for mantra, homa, and Linga-puja.
