Read it through once

The more perfect the artist, the more completely separate in him will be the man who suffers and the mind which creates; the more perfectly will the mind digest and transmute the passions which are its material. The emotion of art is impersonal. This depersonalization, or the substitution of art for the artist, is the very condition of the creation of an "objective correlative," which expression must be taken in its very broad sense. The emotion is experienced and articulated by the mind before it is communicated; and the communication consists in an escape from, not an evocation of, the personality of the author.
