Śrīmad-Bhāgavatam · Text 8.11.32
Who is speaking and story frame
न तस्य हि त्वचमपि वज्र ऊर्जितो
बिभेद य: सुरपतिनौजसेरित: ।
तदद्भुतं परमतिवीर्यवृत्रभित्
तिरस्कृतो नमुचिशिरोधरत्वचा ॥ ३२ ॥
na tasya hi tvacam api vajra ūrjito
bibheda yaḥ sura-patinaujaseritaḥ
tad adbhutaṁ param ativīrya-vṛtra-bhit
tiraskṛto namuci-śirodhara-tvacā
Although King Indra hurled his thunderbolt at Namuci with great force, it could not even pierce his skin. It is very wonderful that the famed thunderbolt that had pierced the body of Vṛtrāsura could not even slightly injure the skin of Namuci’s neck.
