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
Para los dvija, los sacerdotes dos veces nacidos, cuando la impureza proviene de la no acumulación (es decir, de no retener la mancha), la purificación se alcanza únicamente con el baño, y no por otro medio. Del mismo modo, para quienes están presentes en el rito y para el consagrado (dīkṣita) con miras al yajña, el baño es el purificador prescrito.
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.
