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
其后更进一步,即便在那些不邪曲、亦未从法中堕落的人群之中,以乞食为生也被称为诸种姓中最下等的生计。因此当守持正当的谋生之道,使对主宰 Pati(湿婆 Śiva)的奉爱得以无染而行,不为依赖与懈怠之垢所污;此二者会令 paśu(个体灵魂)之中的 pāśa(系缚)更为坚固。
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.
