‘vācāla’ kahiye — ‘veda-pravartaka’ dhanya
‘bāliśa’ — tathāpi ‘śiśu-prāya’ garva-śūnya
Word for word: 
vācāla — talkative; kahiye — I say; veda-pravartaka — one who can speak with the authority of the Vedas; dhanya — glorious; bāliśa — childish; tathāpi — still; śiśu-prāya — like a child; garva-śūnya — without pride.
Translation: 
“The word ‘vācāla’ is used to refer to a person who can speak according to Vedic authority, and the word ‘bāliśa’ means ‘innocent.’ Kṛṣṇa spoke the Vedic knowledge, yet He always presents Himself as a prideless, innocent boy.
