Thong was impetuous , self-centered young. One day he went farming early in the morning. He was upset when he had waited and waited for his mother to bring him some food until it was very late. He was very hungry when he looked up for her. When the sun was almost directly overhead , he saw his mother carrying a box of food, walking lamely from a far distance .He immediately got out of the shade of tree to accuse her of being late
'' What kept you so late, MOM ? Don ‘t you know that I'm starving to death?'' Please, don't be upset, son .'' The mother stood panting heavily with great fatigue from a long walk in the blazing sunlight. '' I was sick. But as soon as I could get up, I cooked for you immediately.'' '' Why do you bring me such a small box of rice? It won't be enough for me!'' " But I stuffed the box with a lot of rice though it is small ." " Shut up and give it to me now ,quick!"
Thong grabbed the box of rice from his mother ‘s hand so sharply that she fell down .But he did not pay any attention to her. He abruptly opened the box and ate the food hungrily . After he was full, he realized that what his mother said was true . There was plenty left over in the box.
Thong saw his mother lying still and he rushed to her at once. The poor old woman had hit her head on the floor when she had fallen down and she was dead. Having realized how violently he had treated his mother , he hugged her dead body and cried his heart out . But his mother could in no way come back to life
Thong built a stupa there to dedicate merit to his mother and to keep her bone . The stupa was shaped like that box of rice . People, therefore , called it " The stupa of a small Box of Rice ." It is in Yasothorn province.
