Upamanyu’s Tapas, Shiva’s Indra-Form Test, and the Bestowal of Kshiroda and Gaṇapatya
आस्थायैवं हि शक्रस्य स्वरूपं परमेश्वरः जगामानुग्रहं कर्तुम् उपमन्योस् तदाश्रमम्
āsthāyaivaṃ hi śakrasya svarūpaṃ parameśvaraḥ jagāmānugrahaṃ kartum upamanyos tadāśramam
Ainsi, le Seigneur Suprême, Parameśvara, ayant assumé la forme même de Śakra (Indra), se rendit à l’ermitage d’Upamanyu afin d’y répandre sa grâce.
