PROMOEl encuentro amoroso es, de alguna manera, un viaje hacia la intimidad de otro ser humano. Una odisea en la que cada mirada, abrazo, beso o caricia va aproximándonos a un territorio maravilloso tanto más codiciado cuanto distante a nuestro anhelo o nuestro deseo. Y en esa búsqueda, repleta de presagios y descubrimientos, cada amante asume o descubre miles de formas para saciar sus apetitos, y se extasía con el aparecer de criaturas fantásticas escodidas en los abismos de las pieles. La poesía, fiel a su origen de celebrar lo esencial del hombre, ha exaltado o elogiado las placenteras peripecias de la aventura erótica; también ha servido de estímulo o motivo para incitar a novatos o tímidos exploradores a lanzar sus naves de palabras seductoras; y lo que parece más importante, al emplear sus metáforas y la magia de sus imágenes, ha buscado detener aquellos episodios de la pasión amorosa, con el fin de convertidos en espejos de agua donde los enamorados logren, pasado el tiempo, reconocerse y reafirmarse como cómplices de un viaje delicioso y memorable. -
