नन्दिकेश्वरोत्पत्तिः — Nandikesvara’s Origin, Shiva’s Boons, and the Rise of Sacred Rivers
प्रावर्तत नदी पुण्या ऊचुर् जम्बूनदीति ताम् एतत्पञ्चनदं नाम जप्येश्वरसमीपगम्
prāvartata nadī puṇyā ūcur jambūnadīti tām etatpañcanadaṃ nāma japyeśvarasamīpagam
Then a sacred river began to flow. They called it the Jambū River. This tīrtha is known as Pañcanada, situated near Japyeśvara—by nearness to the Lord Pati it grants purifying merit to the bound paśu.
Suta Goswami (narrating the tirtha account to the sages of Naimisharanya)
It establishes a Śiva-kṣetra (Japyeśvara) where a sacred river and the Pañcanada tīrtha arise; such proximity to the Linga/Lord is presented as a direct means for accruing puṇya and purification supportive of Śiva-pūjā.
Śiva is implied as Pati—the sanctifying presence whose sannidhya (nearness) transforms place into tīrtha, enabling the paśu (bound soul) to loosen pāśa (bondage) through purity and devotion.
Tīrtha-sevā—pilgrimage, bathing, japa and worship near Japyeśvara—functions as preparatory purification aligned with Pāśupata discipline (inner cleansing supporting mantra-japa and Śiva-pūjā).
