Once a traveller was carrying a bundle of food on his head. He walked a short distance. As the bundle was a burden on him, he could not walk far. On the way, he came across a river. He sat down on its bank, opened his bundle and ate all the food. As long as the food was outside, it was a burden. Was it still a burden after it reached his stomach?
