Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 8
Sanskrit:
गदयाभिहतोऽप्याजौ न चचाल यदूद्वह: ।कृष्णोऽपि तमहन् गुर्व्या कौमोदक्या स्तनान्तरे ॥ ८ ॥
ITRANS:
gadayābhihato ’py ājauna cacāla yadūdvahaḥkṛṣṇo ’pi tam ahan gurvyākaumodakyā stanāntare
Translation:
Although hit by Dantavakra’s club, Lord Kṛṣṇa, the deliverer of the Yadus, did not budge from His place on the battlefield. Rather, with His massive Kaumodakī club the Lord struck Dantavakra in the middle of his chest.
