The Elephant Who Remembered Kindness
Retold for young children from Jataka Tales (retold by Ellen C. Babbitt, 1912), public domain.
A group of carpenters worked each day cutting wood near a great forest. One morning, an elephant limped up to them, holding one sore foot in the air — a splinter, deep and painful, was stuck in it.
The carpenters carefully pulled the splinter out and cleaned the wound until it healed. Grateful, the elephant decided to repay them: from then on, he helped pull logs, carried their tools, and worked alongside them every day, and in return they always fed him well.
Years later, the elephant brought his own son, a beautiful young elephant white all over, to help the carpenters too, teaching him everything he knew. In the evenings, the young elephant loved playing with the carpenters' children by the river, lifting them gently into the trees and letting them slide down his back.
One day, a king passed by and saw this remarkable white elephant and wanted him for his own, paying the carpenters a generous price. The young elephant looked back once at his playmates before going on with the king, who cared for him well for the rest of his days.
Talk about it (ours, not from the source): the first elephant remembered a kindness and repaid it for years afterward. Is there someone who has helped you that you could thank today?
