Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
तदेव लभ्यं नान्यत्तु विष्णुमुद्यम्य वा प्रभुम् निशम्य वचनं मातुर् उपमन्युर्महाद्युतिः
tadeva labhyaṃ nānyattu viṣṇumudyamya vā prabhum niśamya vacanaṃ mātur upamanyurmahādyutiḥ
「得るべきはそれのみ、他にはない。」母の言葉を聞いた大いなる光輝のウパマニュは、主ヴィシュヌを求めんと決し、至上へと精進を向けた。
Suta Goswami (narrating the Upamanyu episode within the Linga Purana’s Shaiva framework)
It establishes ekānta-niścaya—exclusive seeking of the highest goal—as the inner prerequisite for Linga-upāsanā, where the pashu (soul) turns away from secondary aims and seeks the Supreme.
Though Vishnu is named, the Linga Purana’s Shaiva theology frames the “Prabhu” as the supreme Pati-tattva—lordship beyond all pasha (bondage)—toward whom the seeker’s entire effort must be directed.
The practice highlighted is the yogic foundation of sadhana: firm resolve and one-pointed striving (udyama with niścaya), which in Pashupata-oriented devotion precedes mantra, vrata, and puja.
