Adhyaya 89: शौचाचारलक्षणम् — सदाचार, भैक्ष्यचर्या, प्रायश्चित्त, द्रव्यशुद्धि, आशौच-निर्णय
भस्मशायी भवेन्नित्यं भिक्षाचारी जितेन्द्रियः य इच्छेत् परमं स्थानं व्रतं पाशुपतं चरेत्
bhasmaśāyī bhavennityaṃ bhikṣācārī jitendriyaḥ ya icchet paramaṃ sthānaṃ vrataṃ pāśupataṃ caret
常に聖灰の上に臥し、托鉢により生き、諸根を制した者となれ。最高の境地(主宰パティたるシヴァの住処)を願う者は、パーシュパタの誓戒を修すべきである。
Suta Goswami (narrating the Pāśupata-vrata teaching within the Linga Purana discourse)
It links inner purity and renunciation (bhasma, alms-living, sense-control) with eligibility for the highest fruit of Śiva-upāsanā, presenting the Pāśupata vow as a direct discipline for approaching the supreme state of Paśupati.
Śiva is implied as Pati (Paśupati), the supreme station sought by the bound soul (paśu); reaching Him requires loosening pāśa (bondage) through self-mastery and austerity rather than mere external ritual.
The Pāśupata-vrata: ash-observance (bhasma as a mark of dispassion and purification), bhikṣā-based living, and indriya-jaya (sense conquest) as core ascetic-yogic components.
