Translation:

Lord Krsna, the Supreme Personality of Godhead and master of all masters of mystic yoga, was aware of what the gopis were doing, and thus He went there surrounded by His young companions to award the gopis the perfection of their endeavor.

Purport:

As the master of all masters of mystic power, Lord Krsna could easily understand the desires of the gopis, and He could also fulfill them. The gopis, like all young girls from respectable families, considered the embarrassment of appearing naked before a young boy to be worse than giving up their lives. Yet Lord Krsna made them come out of the water and bow down to Him. Although the bodily forms of the gopis were all fully developed, and although Krsna met them in a secluded place and brought them fully under His control, because the Lord is completely transcendental there was not a trace of material desire in His mind. Lord Krsna is the ocean of transcendental bliss, and He wanted to share His bliss with the gopis on the spiritual platform, completely free of ordinary lust.

Srila Visvanatha Cakravarti Thakura explains that the companions of Krsna mentioned here were mere toddlers two or three years old. They were completely naked and were unaware of the difference between male and female. When Krsna went out to herd the cows, they followed Him because they were so attached to Him that they could not bear to be without His association.
