Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
ततो निशम्य वचनं मुनेः कुपितवत्प्रभुः प्राह सव्यग्रमीशानः शक्ररूपधरः स्वयम्
tato niśamya vacanaṃ muneḥ kupitavatprabhuḥ prāha savyagramīśānaḥ śakrarūpadharaḥ svayam
ついで仙人の言葉を聞くや、主は—釈迦羅の姿を取ったイーシャーナ(Īśāna)その人—怒れるがごとき、動揺した面持ちで語った。
Suta (narrator), reporting Īśāna (Shiva) speaking while disguised as Śakra/Indra
It frames Shiva (Īśāna) as the sovereign Pati who may even adopt disguises and stern speech to correct beings—an inner principle of Linga worship where the devotee learns to see the Lord beyond outer forms and reactions.
Shiva-tattva is shown as Īśāna: independent and all-governing, able to assume any form (here Śakra) and employ seeming anger as a pedagogic device, not as human passion—guiding the pashu away from pasha.
The takeaway is Pāśupata discipline of viveka (discriminative insight): do not judge divinity by surface emotion or disguise; maintain steadiness and reverence—qualities that support mantra-japa, liṅga-pūjā, and inner yoga.
