A horse once had a whole meadow to himself, but a stag came and damaged the grassland. Anxious to gain revenge, the horse asked a man if he would help him punish the stag.
“Yes,” said the man, “but you must let me put a bit in your mouth and get on your back. Then I’ll find the weapons punish the stag.”
The horse agreed, and the man mounted him. From that time on, however, instead of gaining revenge, the horse has been the slave of mankind.
Old Learning: Revenge may be not be worth the price when you pay for it with your liberty.
Here the man didn’t kept his promise. Always see from whom you are seeking help. A wrong person can take advantage of your situation.
