Ran across this story today, while I was in search of something else (my favorite mode of discovery, whether on the web or in a library).
As Gandhi boarded a train, one of his shoes slipped off and landed on the track. He was unable to retrieve it as the train was moving. To the amazement of his companions, Gandhi calmly took off his other shoe and threw it back along the track to land close to the first. Asked by a fellow passenger why he did so, Gandhi smiled and replied, "The man who finds the shoes lying on the track will now have a pair he can use."
Haven't been able to find an original source / citation for this story yet - any ideas?
