"In many ways," he answered, sadly. "The jewel, which nothing external can dim, is sensitive to the least change in us. Any infringement of our King's laws, or, especially, any unfaithfulness to our King, dims its lustre at once; any drinking of these forbidden cups of intoxication dries up the crystal fountain; any yielding to the usurper's service blots out from our magic glass its glorious visions, and the sight of our King in his beauty." "Are there any other dangers?" I inquired. "Countless dangers," he replied. "Especially three devices have been found too successful against us. Our jewel only keeps bright with use, and in three ways our enemies endeavour to deter us from using it. The timid they threaten, and induce to hide it from fear: and the cowardly concealing of our treasure inflicts on us two evils: it prevents our winning by it fresh followers to our Prince; and in concealment the jewel itself invariably grows dim. The young and careless they engage in the ambitious pursuits or the gay amusements of the court, until they forget to use the precious gem, and in ceasing to use it, they necessarily cease to shine with its light, and grow like any of the usurper's train. "And again, there are some poor, and distrusting, and fearful ones, whom our enemies persuade that it is a daring presumption for such as they to pretend they have had especial communication with the King, and even at times torment them into thinking the King's own jewel tinsel. So that, in looking and looking to see if it is a true jewel, they forget to clasp it on their hearts, or drink the living water, or look through the magic glass." "That is a strange delusion," I remarked. "Yes," he said; "but it is easily cured, if once we can persuade them to look through the jewel instead of looking at it; for then they see the King with the jewel on his breast, and the smile in his eyes, and their doubts melt away in floods of happy tears. "This I know," he added, "for I was once one of these. I had neglected to use my jewel; and then an enemy, in the guise of a friend, persuaded me to question its genuineness; but I ventured to look through it once again, and since then, I do not look at my jewel, but gaze through it to the King's heart; and from that day, my jewel has not grown dim." "But you spoke of some who lost it altogether," I said. "They are those," he said, solemnly, "who have deliberately yielded it up to enter the service of the usurper, or those who, in base timidity, have cast it away in denying our King." "And for such can it ever be recovered?" I said. "For one such, as disloyal as any, it was," he answered. "He went out and wept bitterly; the King forgave him, and in time the treasure was restored to him, and he became one of our most glorious veterans." "How is the jewel to be recovered if lost?" I asked.
