Translation:
The peacocks became festive and cried out a joyful greeting when they saw the clouds arrive, just as people distressed in household life feel pleasure when the pure devotees of the infallible Supreme Lord visit them.
Purport:
After the dry summer season, the peacocks become jubilant with the arrival of the first thundering rain clouds, and thus they dance in great happiness. Srila Prabhupada comments, “We have practical experience of this: many of our students were dry and morose previous to their coming to Krsna consciousness, but having come into contact with devotees they are now dancing like jubilant peacocks.”
