"I am old and full of tears, and I see that you also begin to feel the sorrow that is born with us. Abandon hope: do not abandon desire. Feel no wonder that these glimpses of your Island so easily confuse themselves with viler things, and are so easily blasphemed. Above all, never try to keep them, never try to revisit the same place or time wherein the vision was accorded to you. You will pay the penalty of all who would bind down to one place or time within our country that which our country cannot contain. Have you not heard from the Stewards of the sin of idolatry, and how in their old chronicles, the manna turned to worms if any tried to hoard it? Be not greedy, be not passionate; you will but crush dead on your own breast with hot, rough hands the thing you loved. But if ever you incline to doubt that the thing you long for is something real, remember what your own experience has taught you. Think that it is a feeling, and at once the feeling has no value. Stand sentinel at your own mind, watching for that feeling, and you will find--what shall I say--a flutter in the heart, an image in the head, a sob in the throat: and was that your desire? You know that it was not, and that no feeling whatever will appease you, that feeling, refine it as you will, is but one more spurious claimant--spurious as the gross lusts of which the giant speaks. Let us conclude then that what you desire is no state of yourself at all, but something, for that very reason, Other and Outer. And knowing this you will find tolerable the truth that you cannot attain it. That the thing should be, is so great a good that when you remember "it is" you will forget to be sorry that you can never have it. Nay, anything that you could have would be so much less than this that its fruition would be immeasurably below the mere hunger for this. Wanting is better than having. The glory of any world wherein you can live is in the end appearance: but then, as one of my sons has said, that leaves the world more glorious yet."
