卦象变化
焦氏易林
買利求福，莫如南國。仁德所在，金玉為寶。
Seeking profit and blessing, none compares to the southern land. Where benevolence and virtue reside, gold and jade are the treasure.
— 焦延寿《焦氏易林》，公元前一世纪
注释
澤中有火，革之象也。買利求福，莫如南國。仁德所在，金玉為寶。地中有水，師之象也。革後需以紀律統合，方能長治久安。南方為火之方位，文明教化之所聚。詩謂利福之源非掠奪而在仁德，金玉之寶因德而貴重。從革至師，變革之後以仁德治世、以紀律行事，方為真正之富強。散亂之後，惟有組織有序之力量方能守護所得。師者，容民畜眾之道也。
