Varaha-Pradurbhava Context: Prahlada’s Bhakti, Narasimha’s Ugra-Form, and Shiva’s Sharabha Intervention
उग्रो ऽसि सर्वदुष्टानां नियन्तासि शिवो ऽसि नः कालकूटादिवपुषा त्राहि नः शरणागतान्
ugro 'si sarvaduṣṭānāṃ niyantāsi śivo 'si naḥ kālakūṭādivapuṣā trāhi naḥ śaraṇāgatān
汝于诸恶者为威猛可畏之主,能制御而统摄之;然于我等,汝即吉祥之湿婆。愿汝以如迦罗俱吒(Kālakūṭa)般可怖之毒的形相,护佑我等归依者。
Suta Goswami (narrating a devotional stuti spoken by devotees/devas seeking refuge in Shiva)
It frames Linga-bhakti as śaraṇāgati: the devotee approaches Pati (Śiva) as both Ugra (who restrains adharma) and Śiva (who grants auspiciousness), seeking protection through surrender rather than mere petition.
Śiva-tattva is shown as paradoxically one: the same Lord is Ugra toward duṣṭas (those bound to pasha through adharma) and Śiva toward devotees—Pati who rules, restrains, and liberates the pashu through grace.
The key practice is śaraṇāgati (complete taking-refuge) expressed as stuti; in a Pāśupata sense it is the inner act of surrender to Pati, trusting his protection even when he appears in a fearsome form.
