Lancelot sought to enter the chapel, but try as he would he could not pass the broken door, nor find entrance elsewhere. Some invisible power seemed to stand between him and admission to that sacred place.
Then, out of heart at this ill success, he took off his helm and sword, relieved his horse of saddle and bridle, and lay down to sleep before the cross. Night came upon him as he lay there, and with the night came strange visions.
For as he lay but half asleep he saw a sick knight brought thither in a litter. This knight prayed earnestly for aid in his affliction, and as he did so Lancelot saw the silver candlestick come from the chapel to the cross, and after it a table of silver on which was the holy grail. The sick knight crawled painfully to it on his hands and knees, and raised himself so as to touch and kiss the sacred vessel. No sooner had he done so than he grew whole and sound, with all his pain and sickness gone, and rose to his feet with his former strength and vigor.
"Lord, I thank thee deeply," he said; "for through thy infinite grace I am healed of my affliction."
Then the holy vessel returned to the chapel, and Lancelot strove hard to rise and follow it. But his limbs were powerless, and he lay like one chained to the ground.
He now fell into deep slumber, and waked not till near morning. And as he raised himself and sat on the ground he heard a voice in the air, that seemed to come from no earthly lips.
"Sir Lancelot," it said, "more hard than is the stone, more bitter than the wood, more bare than the barren fig-tree, arise and go from hence, and withdraw thyself from this holy place."
Lancelot arose with a heavy heart, for the sense of these words sank deeply within him. But when he sought his horse and helm and sword he found they were gone, for they had been taken by the knight whose healing he had seen.
Deeply depressed and unhappy at this misfortune, he left the cross on foot, and wandered onward till he came to a hermitage on a high hill.
Here he told the hermit what had happened to him, and confessed all the evil deeds of his life, saying that he had resolved to be a different man from what he had been, and to live a higher life than that of doing deeds of arms that men might applaud.
