The poet's mind is in fact a receptacle for seizing and storing up numberless feelings, phrases, images, which remain there until all the particles which can unite to form a new compound are present together.
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.
Like a piece of ice on a hot stove the poem must ride on its own melting. . . . Read it a hundred times; it will forever keep its freshness as a metal keeps its fragrance. It can never lose its sense of a meaning that once unfolded by surprise as it went.
