Meaning for Brindavna dolu Purundaradasar Krithi

Suchitra Sairam - Brindavana Dolu - YouTube

I got this link. (FYI: Sorry I dont know anything about dance, but interested in purandaradasa kritis)

Young Krishna attracts the attention of the gopis in gundavan as he dances away in the gardens. One Gopi says to another, "look how he dances among the flowering trees - moving with such energy and joy. He is decorated so beautifully - adorned with bright gems and his earrings that dance with him. He is admired by the gods and demons alike and selflessly offers his blessings to all."

hope this is useful.
