From the folklore of the Bhuiya
The Sun and Moon were great Zamindars. One day the gods came to take a loan from them, but the Sun and Mood said, “We have not enough; go to the money-lender instead.” The gods prepared to go. Hearing they were coming, the money-lender cooked twelve measures of rice, twelve troughs of vegetables and brought twelve troughs of water. When the gods arrived, they said, “Give us a loan.” But Bhimsen said, “First give me something to eat and then your loan.” The merchant said, “Go, the food is ready.” Bhimsen went and in two great mouthfuls finished the whole feast.
When the money-lender saw that his careful preparations were useless he was very angry and said, “I will give you nothing.” Bhimsen too lost his temper and they quarreled. The money-lender showed him two great grain-bins and said, “If you can lift these, you can take them away.” Bhimsen tried, but even he could not lift them up, so he broke them and took as much grain as he could carry and cried, “The Sun and Moon are my sureties for this loan.”
After Bhimsen had gone away the money-lender came. When he saw the broken bins he was very angry. He sent his servants to find Bhimsen, but they were unable to catch him, for he had crossed a great river. So the money-lender sent his servants to catch the Sun and Moon. He is always doing this and, whenever his servants catch them, there is an eclipse.
