孔子曰：“益者三乐，损者三乐。乐节礼乐，乐道人之善，乐多贤友，益矣。乐骄乐，乐佚游，乐宴乐，损矣。”
1Confucius said, 'There are three things men find enjoyment in which are advantageous, and three things they find enjoyment in which are injurious. To find enjoyment in the discriminating study of ceremonies and music; to find enjoyment in speaking of the goodness of others; to find enjoyment in having many worthy friends:-- these are advantageous. To find enjoyment in extravagant pleasures; to find enjoyment in idleness and sauntering; to find enjoyment in the pleasures of feasting:-- these are injurious.'
