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. Śrīla Prabhupāda comments, “We have practical experience of this: many of our students were dry and morose previous to their coming to Kṛṣṇa consciousness, but having come into contact with devotees they are now dancing like jubilant peacocks.”
