dig wells for them, receive travellers hospitably, for that is a sacred duty, and erect inns for them.[464] If the Brahmans are cautioned against the killing of animals, and the eating of flesh is restricted among them as much as possible (p. 168), Buddha is still more strict in this respect. Nothing that has life is to be put to death, neither man nor animal; pain is not to be inflicted on any living creature; a man must have sympathy with the sufferings even of animals, and tend such as are old and weak. Consistent in his attempt to discover the alleviation of pain in the heart and mind of man, Buddha remits even the sins of commission by internal change and improvement of mind. If a man has committed a sin of thought, word, or act,[465] he must repent and acknowledge it before his co-religionists, and those who have attained a higher degree of liberation. Repentance and confession diminish or blot out the sin, according to the degree of their depth and sincerity, and not painful penances and expiations, which only increase the torments of the body, the thing which we desire to diminish.[466] No one is to make a parade of good works; these he should conceal, and publish his failings.[467] Thus the ethics of Buddha are comprehended in the three principles of chastity, patience, and mercy, _i.e._ of a moderate and passionless life, of ready and willing submission to any annoyance or unavoidable evil, and finally of sympathy and active assistance for our fellow-men. An old formula tells us: "The eschewing of evil, the doing of good, the taming of our own thoughts, this is the doctrine of Buddha."[468]
