It was at the age of forty-seven that Wang gained a great victory over the rebel army, and wrote to a friend saying: “It is so easy to gain a victory over the rebels fortifying themselves among the mountains, yet it is not so with those rebels living in our mind."[FN#266] Tsai Kiun Mu (Sai-kun-bo) is said to have had an exceedingly long and beautiful beard, and when asked by the Emperor, who received him in audience, whether he should sleep with his beard on the comforters or beneath them, be could not answer, since he had never known how he did. Being distracted by this question, he went home and tried to find out how he had been used to manage his beard in bed. First he put his beard on the comforters and vainly tried to sleep; then he put it beneath the comforters and thought it all right. Nevertheless, he was all the more disturbed by it. So then, putting on the comforters, now putting it beneath them, he tried to sleep all night long, but in vain. You must therefore forget your mental beard that annoys you all the time.

Men of longevity never carried troubles to their beds. It is a well-known fact that Zui-o (Shi-ga)[FN#267] enjoyed robust health at the age of over one hundred years. One day, being asked whether there is any secret of longevity, he replied affirmatively, and said to the questioner: “Keep your mind and body pure for two weeks, abstaining from any sort of impurity, then I shall tell you of the secret.” The man did as was prescribed, and came again to be instructed in the secret.
