Why is the rain divine?

The poet has personified the rain and making it appear divine. The poet describes it to have descended from the heaven as if been delivered to the nature by the hands of God. The rain has been compared to the pearls embedded in the crown of Ishtar (the goddess of fertility, love, war and sex), plucked by the daughter of Dawn. The poet calls the Rain a messenger of mercy between the field and the clouds (two lovers). There is a fine use of sensual expression here, how the rain quenches the thirst of one of the lovers and cures the ailment of the other. Thus, the Rain is divine because it quenches the thirst of the dry earth and makes it blossom. It infuses a new life in plants and trees.
