This short moral story has been taken from the Panchatantra Collections about a Lion and the Foolish Donkey.
There were Lion and his assistant Jackal in a forest. One day the Lion went on a fierce battle with the elephant and got injured badly. The Lion was injured so much that he couldn't even walk, hunting was out of the question for him.
As Lion was not hunting, Jackal also didn't eat for a few days. One day Jackal said to Lion, "O Master, I am not being able to serve you because I am too weak. I have not eaten for several days."
