नन्दिकेश्वरोत्पत्तिः — Nandikesvara’s Origin, Shiva’s Boons, and the Rise of Sacred Rivers
यः पञ्चनदमासाद्य स्नात्वा जप्येश्वरेश्वरम् पूजयेच्छिवसायुज्यं प्रयात्येव न संशयः
yaḥ pañcanadamāsādya snātvā japyeśvareśvaram pūjayecchivasāyujyaṃ prayātyeva na saṃśayaḥ
Ai đến Pañcanada, tắm gội tại đó, trì tụng (japa) danh hiệu Īśvareśvara—Đấng Chúa Tể của các Chúa Tể—và thờ phụng Ngài, thì dù là pashu (linh hồn bị trói buộc) cũng chắc chắn đạt sāyujya với Śiva, hợp nhất cùng Pati; điều ấy không còn nghi ngờ.
Suta Goswami (narrating to the sages of Naimisharanya)
It teaches that tirtha-purification (snāna), mantra-japa, and direct worship of Śiva together become a complete sādhana that culminates in Śiva-sāyujya—showing the Linga Purana’s emphasis on disciplined upāsanā rather than mere travel to a holy place.
Śiva is called Īśvareśvara, the Supreme Pati beyond all lesser īśvaras; union with Him (sāyujya) is presented as the highest fruit, implying that liberation is attained by approaching the Lord as the ultimate controller and liberator of the pashu from pāśa (bondage).
A threefold practice: tirtha-snānā (ritual bath for purification), mantra-japa of Śiva, and pūjā (formal worship). Together they function as a Shaiva sādhana aligned with Pāśupata-oriented purification and devotion leading toward mukti.
