One day, he paid us a visit while we were repeating our breviary in our little chapel; he stopped short a few steps from the door, and awaited in grave silence. A large coloured image, representing the Crucifixion, had no doubt fixed his attention; for, as soon as we had finished our prayers, he asked us abruptly and without staying to make the usual salutations, to explain to him the meaning of that image. When we had answered his question, he crossed his arms upon his chest, and without uttering a single word, remained motionless, his eyes fixed upon the image of the Crucifixion; he retained this position for nearly half-an-hour; at length his eyes were filled with tears. He extended his arms towards the Christ, fell on his knees, struck the earth thrice with his forehead, and rose, exclaiming, “That is the only Buddha that men ought to worship.” He then turned to us, and after making a profound bow, added, “You are my masters, accept me as your disciple.” All this surprised us greatly. We could not help believing that a powerful impulse of grace had moved his heart. We briefly explained to him the principal points of the Christian religion, and to all we told him, he simply replied with an expression of faith truly astonishing, “I believe!” We presented to him a small crucifix of gilt copper, and asked him if he would accept it. His only answer was an earnest inclination of the head. As soon as he had the crucifix in his hand, he solicited us to give him a cord, and he immediately hung the cross round his neck; he then asked what prayer he ought to recite before the cross? “We will lend you,” we said, “some Chinese books, wherein you will find explanations of the doctrine, and numerous forms of prayer.” “My masters, that is well; but I wish to have a short and easy prayer, which I can learn immediately, and repeat often and everywhere.” We taught him to say, “Jesus, Saviour of the world, have mercy on me.” For fear of forgetting these words, he wrote them on a piece of paper, which he placed in a small purse, suspended from his girdle; he then went away, assuring us that the recollection of this day would never be effaced from his memory. This young physician applied himself with ardour to learn the truths of the Christian religion; but the most remarkable circumstance was, that he took no pains to hide the faith he had in his heart. When he came to visit us, or when we met him in the streets, he always had the crucifix glittering on his breast, and he never failed to approach us with the words, “Jesus, Saviour of the world, have mercy on me.” It was the form of saluting us which he had adopted.
