"I am like earthly life … "

Why does the poet call rain as earthly life?

The poet draws a parallel between the Rain and an earthly life. The Rain nourishes the plants and trees and flowers and fields, it gives life to the flora and fauna and also it dies by showering itself over the fields. It rises from the various water bodies through evaporation which is its birth; its dies a death, the poet describes like a mortal one, by showering down its weight over the fields like shedding tears of heaven. Yet, the death of the Rain is an honourable one, as it serves the humanity and the flora and fauna while it dies. And so is the life of the Rain.
