Rain

1. In the Ramayana, Surabhi is described to be distressed by the treatment of her sons—the oxen—in fields. Her tears are considered a bad omen for the gods by Indra, the god-king of heaven. 
2. The Vana Parva book of the Mahbharata also narrates a similar instance: Surabhi cries about the plight of her son—a bullock, who is overworked and beaten by his peasant-master. Indra, moved by Surabhi's tears, rains to stop the ploughing of the tormented bullock.
