What a poem means is as much what it means to others as what it means to the author; and indeed, in the course of time a poet may become merely reader in respect to his own works, forgetting his original meaning.
It is very difficult to pass from pleasure to work. Accordingly more poems have been swallowed up by sorrow than ever happiness caused to blaze forth in unparalleled radiance.
Poetry may make us from time to time a little more aware of the deeper, unnamed feelings which form the substratum of our being, to which we rarely penetrate; for our lives are mostly a constant evasion of ourselves.
