Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
अस्तेयं ब्रह्मचर्यं च अलोभस्त्याग एव च व्रतानि पञ्च भिक्षूणाम् अहिंसा परमा त्विह
asteyaṃ brahmacaryaṃ ca alobhastyāga eva ca vratāni pañca bhikṣūṇām ahiṃsā paramā tviha
For the mendicant devoted to Pati (Lord Śiva) there are five observances: non-stealing, brahmacarya (sacred chastity), non-covetousness, and renunciation; and here ahiṃsā (non-violence) is declared the supreme vow, for it loosens the pāśa-bonds that bind the paśu, the individual soul.
Suta Goswami (narrating the dharma-teachings within the Linga Purana framework)
It frames Linga-upāsanā as inseparable from inner purification: the bhikṣu’s vows—especially ahiṁsā—prepare the devotee to approach Śiva (Pati) with a mind free from harm and grasping.
Śiva-tattva is implied as Pati, the liberating Lord: when the paśu practices restraint and non-violence, pāśa (bondage) weakens, making the soul fit for Śiva’s grace and union in devotion.
A Pāśupata-oriented yama-like discipline for mendicants: asteya, brahmacarya, alobha, tyāga, with ahiṁsā upheld as the highest regulating principle for sādhanā.
