Justify the title of the poem The voice of the rain

The poem written by Walt Whitman, 'The Voice of the Rain' is about an imaginative conversation which the poet once had with the rain. It appears that the poet had asked the soft falling shower as to who it was and strangely the shower seemed to have answered the question which the poet translates. According to the translation the rain is explaining that it is the poem of earth, it originates from the impalpable land and the bottomless sea. From here it goes on to the heaven where it changes its form but retains its characteristics. It then descends from the sky in the form of rain to save earth from drought, wash away the dust on earth. All those living beings on earth which were not able to grow without the rain are brought to life by it. Thus in this way the rain purifies and beautifies its origin like a song which originates from the heart. Like the song it wanders and entertains others whether being liked or not by people, it travels back to where it originated with love and care. The poet in this poem is trying to illustrate the significance of  rain in our lives.  Using the imaginative conversation between him and rain he is trying to point out that the rain does have a voice and even compares it with a song. The poet sees the rain as an entity with a voice which is indispensable for the survival of the earth. Therefore the title of the poem is justly chosen by the poet.
