焦氏易林
三羖五牂，相隨俱行；迷入空澤，經涉六駮，為所傷賊。
Three black bucks, five white ewes, following one another in a line. Straying into an empty marsh, they pass through dappled beasts and are wounded and preyed upon.
— 焦延寿《焦氏易林》，公元前一世纪
注释
天與火同人，然群羊誤入險地。三羖五牂相隨俱行，迷入空澤——看似無害之沼地。途中遭遇六駮，傳說中之猛獸，群羊為其所傷。同人之群體若無辨識之力，則結伴反成禍端：盲從者相偕入險。從同人至蒙（山下出泉），揭示天真群聚之代價。蒙卦山下出泉，君子以果行育德——蒙昧者須經痛苦之遭遇方能覺悟。空澤非空，暗藏利齒，群體之無知恰將自身送入獵場。
