The explanation of the chapter "song of the rain"
the poet writes that it (rain) is sent on earth by the gods. nature welcomes rain to beautify her fields and valleys.
he says he was once pearls on the crown of queen ishtar but was plucked by the goddess of dawn to embellish the earth.
he says that when there is rainfall all things are filled with joy and happiness.
he says that the fields and clouds are its lovers because-- it satisfies the need of water in the field , it lessen the heavy burden of the cloud.
before rainfall , thunder strike and announces the rains entry. the spotting of a rainbow shows its end.
rain has its roots in the sea ( evaporation). whenever it sees a dying field it showers water and rejuvenates flowers and tress
the pitter- patter against the window sill is always welcome but only few appreciate it .
heat causes evaporation and ultimately rainfall, rainfall however makes the atmosphere cool.
stanza 9 and 10
it says it evaporates from the sea, makes fields happy and is the tears of heaven.
