《礼记·经解》
如果为人温和柔顺、纯朴忠厚而又不愚钝，那就是深刻地理解了《诗》；开明通达、博古通今而又不浮夸，那就是深刻地理解了《书》；心胸舒畅、轻松和善而又不奢侈，那就是深刻地理解了《乐》；清静精明、细致入微而又不害正道，那就是深刻地理解了《易》；谦恭辞让、庄重严肃而又不烦琐，那就是深刻地理解了《礼》；善于辞令、议论是非而又不混乱，那就是深刻地理解了《春秋》。 
故《诗》之失，愚；《书》之失，诬；《乐》之失，奢；《易》之失，贼；《礼》之失，繁；《春秋》之失，乱。其为人也：温柔敦厚而不愚，则深于《诗》者也；疏通知远而不诬，则深于《书》者也；广博易良而不奢，则深于《乐》者也；洁静精微而不贼，则深于《易》者也；恭俭庄敬而不烦，则深于《礼》者也；属辞比事而不乱，则深于《春秋》者也。 
If one is gentle, simple and honest, but not dull, then he deeply understands "Poetry"; if one is open-minded, knowledgeable and well-informed, but not exaggerated, then he deeply understands "Book"; if one is relaxed, kind and friendly, but not extravagant, then he deeply understands "Music"; if one is clear, subtle and meticulous, but does not harm the right way, then he deeply understands "Change"; if one is humble and courteous, dignified and serious, but not complicated, then he deeply understands "Ritual"; if one is good at rhetoric and arguing about right and wrong, but not chaotic, then he deeply understands the "Spring and Autumn Annals".
