At one time the horse had the plain entirely to himself。 Then a stag intruded into his domain and shared his pasture。 The horse， desiring to revenge himself on the stranger，asked a man if he were willing to help him in punishing the stag。 The man replied that if the horse would receive a bit in his mouth and agree to carry him，he would contrive effective weapons against the stag。The horse consented and allowed the man to mount him。From that hour he found that instead of obtaining revenge on the stag，he had enslaved himself to the service of man。

Revenge may be not worth the price when you pay for it with your liberty。

從前馬獨自享用一片草原，一天鹿闖入了他的領地，與他爭享草原。為此馬企圖報復這個不速之客，就請求人來幫助他趕走鹿，以懲罰這個討厭的傢伙人，答應的條件是能夠讓人在他嘴上安上一個嚼子，再允許人騎在他的背上，這樣人就可以拿起武器替他報仇。為了趕走鹿，馬毫不遲疑的同意了人的條件。然而他很快就發現，鹿還沒有趕走，他自己已經成了人的奴隸，只能供人調遣為其效力了。

付出自由的代價去復仇，是不值得的。
