Two well-assorted travellers use <br />The highway, Eros and the Muse. <br />From the twins is nothing hidden, <br />To the pair is naught forbidden; <br />Hand in hand the comrades go <br />Every nook of nature through: <br />Each for other they were born, <br />Each can other best adorn; <br />They know one only mortal grief <br />Past all balsam or relief, <br />When, by false companions crossed, <br />The pilgrims have each other lost.<br /><br />Ralph Waldo Emerson<br /><br />http://www.poemhunter.com/poem/love-and-thought/
