The Voice Of The Rain - Poem by Walt Whitman
And who art thou? said I to the soft-falling shower,
Which, strange to tell, gave me an answer, as here translated: I am the Poem of Earth, said the voice of the rain, Eternal I rise impalpable out of the land and the bottomless sea, Upward to heaven, whence, vaguely form'd, altogether changed, and yet the same, I descend to lave the drouths, atomies, dust-layers of the globe, And all that in them without me were seeds only, latent, unborn; And forever, by day and night, I give back life to my own origin, and make pure and beautify it; (For song, issuing from its birth-place, after fulfilment, wandering, Reck'd or unreck'd, duly with love returns.)
Hearing this, the poet compares it to a song, which rises from its birthplace (the heart) roams around for a bit, and, whether heard and enjoyed or not, returns back to the heart and settles there when he stops singing, remaining a happy memory.
