नन्दिकेश्वरोत्पत्तिः — Nandikesvara’s Origin, Shiva’s Boons, and the Rise of Sacred Rivers
प्रदक्षिणीकृत्य च तं रुद्रजाप्यरतो ऽभवम् हृत्पुण्डरीके सुषिरे ध्यात्वा देवं त्रियंबकम्
pradakṣiṇīkṛtya ca taṃ rudrajāpyarato 'bhavam hṛtpuṇḍarīke suṣire dhyātvā devaṃ triyaṃbakam
Sau khi đi nhiễu quanh Ngài, tôi chuyên tâm trì tụng thần chú Rudra; và quán niệm đấng Tryambaka ba mắt trong khoảng rỗng vi tế của hoa sen nơi tim, tôi an trụ tâm thức nơi Pati, bậc giải thoát paśu khỏi pāśa.
Suta Goswami (narrating an internal devotional practice account within the Purva-Bhaga narrative)
It links outer Linga-upacāra (pradakṣiṇā/circumambulation) with inner worship—Rudra-japa and meditation on Tryambaka in the heart-lotus—showing that true Linga devotion culminates in internalization of Shiva as Pati.
Shiva is invoked as Tryambaka, the all-seeing Lord, approachable through mantra and dhyāna; as Pati, He is the liberator whose grace loosens pāśa (bondage) and elevates the paśu (individual soul) toward freedom.
A combined sādhana: pradakṣiṇā as devotional rite, Rudra-japa as mantra discipline, and hṛt-puṇḍarīka-dhyāna (heart-lotus meditation) aligned with Pāśupata-oriented inner worship.
