महिषश्चैव शुंभश्च उभौ वध्यौ च योषिता । जंभो दुर्वाससा शप्तः शक्रवध्यो भवानिति । तस्मात्त्वं दिव्यवीर्येण जहि जंभं मदोत्कटम्
mahiṣaścaiva śuṃbhaśca ubhau vadhyau ca yoṣitā | jaṃbho durvāsasā śaptaḥ śakravadhyo bhavāniti | tasmāttvaṃ divyavīryeṇa jahi jaṃbhaṃ madotkaṭam
“摩醯沙（Mahiṣa）与顺婆（Śuṃbha）——二者皆当为女神所诛。惟有阎婆（Jambha）曾被杜尔婆娑（Durvāsas）诅咒：‘你将为释迦罗（Śakra，因陀罗）所杀。’故当以你神圣的勇力，诛灭那因醉傲而膨胀的阎婆。”
Keśava (Viṣṇu) (contextual: advising Indra with knowledge of boons/curses)
Scene: A divine council scene: Viṣṇu (Vaikuṇṭha) indicates the destined slaying—Mahiṣa and Śumbha by a woman, Jambha by Indra—while the daitya Jambha is shown intoxicated with pride, towering like a thorn to the worlds.
