Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 35
Sanskrit:
आधावत: सगदं तस्य बाहुंभल्लेन छित्त्वाथ रथाङ्गमद्भुतम् ।वधाय शाल्वस्य लयार्कसन्निभंबिभ्रद् बभौ सार्क इवोदयाचल: ॥ ३५ ॥
ITRANS:
ādhāvataḥ sa-gadaṁ tasya bāhuṁbhallena chittvātha rathāṅgam adbhutamvadhāya śālvasya layārka-sannibhaṁbibhrad babhau sārka ivodayācalaḥ
Translation:
As Śālva rushed at Him, the Lord shot a bhalla dart and cut off his arm that held the club. Having finally decided to kill Śālva, Kṛṣṇa then raised His Sudarśana disc weapon, which resembled the sun at the time of universal annihilation. The brilliantly shining Lord appeared like the easternmost mountain bearing the rising sun.
