Question

How does the rain quench the thirst of the earth and cure the ailment of the clouds?

Answer 1

In the fourth stanza the rain compares itself to a messenger between the lover cloud and the beloved earth. It is the only way of communication between them. When it falls, the cloud’s pain is relieved, and the earth’s thirst is slaked. The cloud has the ailment of pain to send his heart's message to the beloved earth; and the earth is thirsting to hear the beloved clouds message. When the rain falls, it brings along the love message thus relieving the cloud of his pain and quenching the earth's thirst.
