Once a gentle man was traveling in a train. He felt thirsty and got down at a station in search of water. No sooner had he reached the water tap then the engine whistled and started. He ran back but missed the train. It was getting darker and he decided to spend the night at the station. The next morning he inquired about the next train. He came to know that the next train was on the other day. So he decided to find a place for a day's stay. He went to the nearby lodges to ask for a room but found none. It was getting darker and he could not find a room. At last he reached a small hut. He asked the owner of the hut whether he could stay in his house for a day. The owner readily agreed. That day the owner served him food and gave him a room to stay. But did not ask nor expected anything in return.
