“Poetry, if it is not to be a lifeless repetition of forms, must be constantly exploring "the frontiers of the spirit." But these frontiers are not like the surveys of geographical explorers, conquered once for all and settled. The frontiers of the spirit are more like the jungle which, unless continuously kept under control, is always ready to encroach and eventually obliterate the cultivated area.”

“We must not cease from exploration. And the end of all our exploring will be to arrive where we began and to know the place for the first time.”

“The important fact is that for the man the act is eternal, and that for the brief space he has to live, he is already dead. He is already in a different world from ours. He has crossed the frontier. The important fact is that something is done which can not be undone-a possibility which none of us realize until we face it ourselves.”

“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.”

“The end of all our exploring will be to arrive where we know we started and know the place for the first time.”

“and now you live dispersed on ribbon roads, And no man knows or cares who is his neighbor Unless his neighbor makes too much disturbance, But all dash to and fro in motor cars, Familiar with the roads and settled nowhere.”

“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.”
