What message does the poem "the voice of the rain" gives to the readers?

The rain is a life giving force because it helps the sea by giving life back to its own origin, making it pure and beautifying it at the same time. Rain is issued from the sea and after fulfillment, it duly returns to the sea to replenish it. As human beings, we are part of this large framework that keeps on functioning without the need for human intervention, we must remember the smallness of our stature when seen in context to the vast cosmos. Our lives would not function properly if these natural processes did not happen, such as rain.
