卦象变化
焦氏易林
秦失其鹿，疾走先得。勇夫慕義，君子變服。
Qin lost its deer; the swift runner seizes it first. The brave man, moved by righteousness; the gentleman changes his garb.
— 焦延寿《焦氏易林》，公元前一世纪
注释
山下有澤，損之象。「秦失其鹿，疾走先得」——秦亡天下，如鹿脫逃，疾足者先得之。此語出《史記·淮陰侯列傳》蒯通之言：天下共逐秦之鹿，高材疾足者先得。「勇夫慕義」——勇士仰慕正義而起。「君子變服」——君子改換衣冠，應變於新時代。從損至井（木上有水），山損而水升於木上。井者，不改不移，取之不竭。秦之損盡即天下重新汲取之時。損到極處，舊井枯而新井出。君子變服，非喪其本，乃順時而動。井養而不窮，正是損極而復生之道。
