नन्दिकेश्वरोत्पत्तिः — Nandikesvara’s Origin, Shiva’s Boons, and the Rise of Sacred Rivers
यस्माज्जटोदकादेव प्रवृत्ता त्वं महानदी तस्माज्जटोदका पुण्या भविष्यसि सरिद्वरा
yasmājjaṭodakādeva pravṛttā tvaṃ mahānadī tasmājjaṭodakā puṇyā bhaviṣyasi saridvarā
Porque tú, oh gran río, has brotado de las mismas aguas de las jaṭā, las trenzas ascéticas de Śiva, por ello serás célebre como Jaṭodakā: santa y la más excelsa entre los ríos.
Suta Goswami (narrating; the statement reflects Shiva’s sanctifying decree regarding the river)
It establishes that waters originating from Śiva’s jaṭā carry Śiva’s sanctifying power, making the river a supreme tīrtha; such tīrthas support śuddhi (purification) that is foundational for Liṅga-pūjā.
Śiva is implied as Pati—the supreme source of purification—whose very contact (through jaṭā-udaka) transforms the world, loosening pāśa (bondage) and aiding the pashu (soul) toward auspiciousness.
Tīrtha-snāna (holy bathing) and preparatory śaucācāra (ritual purity) are highlighted; in a Shaiva frame, this supports Pāśupata-oriented inner cleansing prior to mantra-japa and Liṅga-arcana.
