This Fable tells us the story of two donkeys one of whom was a wild donkey that had no boss and the other was a pack donkey that had a master.
You can listen to the Fable by following the link The Wild Donkey & The Pack Donkey.
The story begins with a wild donkey, who is idly wandering about, when he comes upon a pack donkey.
The pack donkey is lying relaxed and enjoying himself in a sunny spot. The wild donkey envies the pack donkey and considers him lucky. But after a while, when he meets him again, the pack donkey is loaded with a heavy cargo and his driver is beating him with a thick stick. At that point the wild donkey realizes the hardship the other donkey has to go through.
This fable shows how a certainty may turn into uncertainty and tell us how appearances are often deceptive. A person may make a mistaken judgement by seeing only one part someone else's life. Thus the wild donkey expresses his envy towards the pack donkey and the life he thinks the other one leads. But he soon realizes his mistake in judgement and he expresses the lesson he has learned by expressing in words the moral of this fable that "Advantages that are dearly bought are doubtful blessings".
The wild donkey stops thinking of the domestic donkey as fortunate once he sees the hard labour and abuse he has to go through in order to have a little bit of rest in a sunny spot, while he himself has the freedom of will and no master upon him.
