The salt merchant and his donkey

Once a salt merchant leaving in a village. He had one donkey. he was taking salt to market putting on the back of the donkey. He was earning a decent profit out of it. He and his family leaving happily. There was a stream on the way to the market. On rainy season this stream passes over the road. 

One day it rain heavily in that eerier. The stream over flowed at that point of road. The salt merchant had to cross the stream to go to the market. As there was no provision to at that place. So he and his donkey have to cross by themselves. They try to cross the stream. As it was overflowing the water dissolved some salt from the back of the donkey. They crossed the stream and went to the other side of the road. The donkey observed that the load has reduced. So he felt happy and went to the merchant.

The next day again the master and the donkey reached the same point. This time the water level has reduced substantially. They could the donkey in order to reduced his burden lower himself in the water. In this process few salts dissolved the water. The donkey became happy. Because he got some relief. Then onward the donkey deliberately lowers himself in the water to reduce the burden. The master observed that and wants to teach a lesson to his donkey. After a few days the master has laden the donkey with sponge instinct of salt. As usual they went to the market in the regular path. 

Once again they came to that same point. The donkey in order to reduce the burden lowers himself in the water. This sponge absorbed lot many water. When they crossed the stream the donkey observed that the load has increased. The water in the sponge increases the load. It gave lot many troubles to the donkey. The donkey observed his folly on that day. Afterward he did not make any mischief like that, while crossing the stream.
