vaiśaṃpāyana uvāca
kāle gacchati saumyau tau dārakau kṛtanāmakau
pañca saṃvatsarān prāptau śobhayānau vrajaṃ muhuḥ |
kṛṣṇasaṃkarṣaṇau cobhau riṅginau samapadyatām //

Vaiśaṃpāyana said: / As time passed, those two gentle boys, having received their names, / reached five years of age, repeatedly adorning the cowherd settlement. / Both Kṛṣṇa and Saṃkarṣaṇa began crawling on all fours.
