This is an excellent video retelling of a story that has become part of the folklore of many traditions. Depending on the culture the diners have long spoons, long chopsticks or long forks. Sometimes an inability to bend their elbows prevents them feeding themselves but the solution is the same ‘feed each other’, in this lies the difference between heaven and hell.
Here is a Chinese version:
There is an ancient Chinese parable about an old man who knew he would die soon. He wanted to know what Heaven and hell were like. He visited a wise man in his village to ask “Can you tell me what Heaven and hell are like?” The wise man led him down a strange path, deep into the countryside. Finally they came upon a large house with many rooms and went inside. Inside they found lots of people and many enormous tables with an incredible array of food. Then the old man noticed a strange thing, the people, all thin and hungry were holding chopsticks 12 feet long. They tried to feed themselves, but of course could not get the food to their mouths with such long chopsticks. The old man then said to the wise man “Now I know what hell looks like, will you please show me what Heaven looks like?” The wise man led him down the same path a little further until they came upon another large house similar to the first. They went inside and saw many people well fed and happy, they too had chopsticks 12 feet long. This puzzled the old man and he asked, “I see all of these people have 12 feet chopsticks too, yet they are well fed and happy, please explain this to me.The wise man replied, “in Heaven we feed each other”
