Poetry is the revelation of a feeling that the poet believes to be interior and personal which the reader recognizes as his own.
Poetry is not a turning loose of emotion, but an escape from emotion; it is not the expression of personality, but an escape from personality.
Poetry is the spontaneous overflow of powerful feelings: it takes its origin from emotion recollected in tranquility.
Poetry is the opening and closing of a door, leaving those who look through to guess about what is seen during the moment.
