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
وبعد أن طفتُ حوله طوافَ التقديس (pradakṣiṇa) صرتُ مواظباً على جَپَا مانترا رودرا؛ ثمّ تأمّلتُ الإله تريامباكا ذا العيون الثلاث في التجويف اللطيف لِلوتس القلب، فثبّتُّ وعيي على باتي مُحرِّر الـpaśu من الـpāśa.
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.
