“But I tried  - and notice I do not boast of results, but only of intentions - to follow a quite distinct road.  I thought that the substance of poetry does not lie in the sound value of the word, nor in its color, nor in the metric line, nor in the complex of sensations, but in the deep pulse of the spirit; and this deep pulse is what the soul contributes, if it contributes anything, with its own voice, in a courageous answer to the touch of the world.  And I thought also that a man can overtake by surprise some of the phrases of his inward conversations with himself, distinguishing the living voice from the dead echoes; that he, looking inward, can glimpse the deep- rooted images, the things of feeling which all men possess."  Antonio Machado
