Sanskrit:

कंसं नागायुतप्राणं मल्लौ गजपतिं यथा ।अवधिष्टां लीलयैव पशूनिव मृगाधिप: ॥ २४ ॥

ITRANS:

kaṁsaṁ nāgāyuta-prāṇaṁmallau gaja-patiṁ yathāavadhiṣṭāṁ līlayaivapaśūn iva mṛgādhipaḥ

Translation:

After all, Kṛṣṇa and Balarāma killed Kaṁsa, who was as strong as ten thousand elephants, as well as the wrestlers Cāṇūra and Muṣṭika and the elephant Kuvalayāpīḍa. They killed them all sportingly, as easily as a lion disposes of small animals.

Purport:

Here Nanda means to say, “Not only did Garga Muni declare that these boys are divine, but just see what They have done! Everyone is talking about it.”
