दशाश्वमेधी पुनरेति जन्म कृष्णप्रणामी न पुनर्भवाय ॥
In plain words
Complete ten horse-sacrifices and you still come back — birth again. Bow to Kṛṣṇa, and there is no coming back.
Close to the Sanskrit
The performer of ten horse-sacrifices comes again to birth; the one who bows to Kṛṣṇa — not for rebirth.
