Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
अत ऊर्ध्वं पुनश्चापि अदुष्टापतितेषु च भैक्ष्यचर्या हि वर्णेषु जघन्या वृत्तिरुच्यते
ata ūrdhvaṃ punaścāpi aduṣṭāpatiteṣu ca bhaikṣyacaryā hi varṇeṣu jaghanyā vṛttirucyate
अतः परं पुनश्चापि अदुष्टापतितेष्वपि वर्णेषु भैक्ष्यचर्या जघन्या वृत्तिरुच्यते। तस्माद् धर्म्यां वृत्तिं धारयेत्, यथा पाशदोषो न वर्धते, पतिभक्तिः शिवे निर्विघ्ना भवेत्॥
Suta Goswami
It frames Shiva-bhakti as supported by dharmic self-discipline: a stable, righteous livelihood prevents tamas and dependency from weakening one’s steadiness in worship and vrata.
By implication, Śiva as Pati is approached through purity of conduct; when the paśu reduces pāśa-like habits (laziness, unethical dependence), devotion becomes fit for the Lord who is the upholder of dharma.
Not a specific rite, but a preparatory discipline aligned with Pāśupata restraint: choosing a proper vṛtti (livelihood) to support tapas, japa, and regular Linga-pūjā without moral compromise.
