In the rainy season, when the clouds appear for the first time, after seeing their appearance, the peacocks begin to dance with joy. This can be compared to persons who are very harassed in the materialistic way of life. If they can find the association of a person engaged in the loving devotional service of the Lord, they become enlightened, just like the peacocks when they dance. We have practical experience of this, because 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.
