सशैवालं तथान्यैर्वा दोषैर्दुष्टं विवर्जयेत् च्लेअनिन्ग् ओफ़् च्लोथेस् वस्त्रशौचान्वितः कुर्यात् सर्वकार्याणि वै द्विजाः
saśaivālaṃ tathānyairvā doṣairduṣṭaṃ vivarjayet cleaning of clothes vastraśaucānvitaḥ kuryāt sarvakāryāṇi vai dvijāḥ
凡被污秽所染者——或如藻垢之类,或由其他过失——皆应弃除。噫,二次生者!具足衣服清净者,当在洁净之境中行一切事务与仪轨,尤当如法而行湿婆相关之行持。
Suta Goswami (narrating Shiva-dharma and śauca rules to the sages of Naimiṣāraṇya)
It establishes śauca—especially clean clothing and avoidance of defiled materials—as a prerequisite for effective Liṅga-pūjā, aligning outer purity with inner devotional focus toward Pati (Śiva).
By insisting on purity before action, it implies that approach to Shiva-tattva requires refinement of the worshipper’s state; the pashu (soul) reduces pasha (impurity/bondage) through disciplined conduct while turning toward Pati.
Ritual śauca (purity) as part of pūjā-vidhi—clean garments and rejection of contaminated items—supporting the Pāśupata-style discipline where external order reinforces inner steadiness.
