na te sraddadhire gopa
bala-bhasitam ity uta
aprameyam balam tasya
balakasya na te viduh
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The assembled gopis and gopas, unaware that Krsna is always unlimited, could not believe that baby Krsna had such inconceivable power. They could not believe the statements of the children, and therefore they neglected these statements as being childish talk.
