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
ఆయనకు ప్రదక్షిణ చేసి నేను రుద్రజపంలో నిమగ్నుడనయ్యాను; హృదయ పద్మంలోని సూక్ష్మ గుహలో త్ర్యంబక దేవుని ధ్యానించాను.
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.
