Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
तथैव यज्ञपात्राणां मुशलोलूखलस्य च शृङ्गास्थिदारुदन्तानां तक्षणेनैव शोधनम्
tathaiva yajñapātrāṇāṃ muśalolūkhalasya ca śṛṅgāsthidārudantānāṃ takṣaṇenaiva śodhanam
同样,祭祀所用之器皿,以及杵与臼,皆当净化;而以角、骨、木或象牙所制之物,则唯以刮削其表面而得清净。
Suta Goswami (narrating Shiva-dharma and ritual purity rules to the Sages of Naimisharanya)
It establishes shaucha (ritual cleanliness) for implements used in yajna and Shiva-puja, indicating that proper external purification supports focused worship of Pati (Shiva) and reduces distractions arising from impurity.
Indirectly, it reflects Shiva as Pati—the supremely pure Reality—toward whom the pashu (bound soul) approaches through disciplines of purity; the rule implies that worship aligns the practitioner with Shiva’s śuddha-tattva by removing gross impurities.
A practical puja-vidhi rule: purification of specific materials by physical scraping (takṣaṇa). As a yogic takeaway, it parallels inner cleansing—refining the mind by removing surface-level pasha (impurities) before mantra and worship.
