This tale is one of the epic tales inscribed in the holy pages of the Puranas.
King Kubera, is the Lord of wealth and is often depicted as a fat man, adorned with jewels and carrying a money-pot or money-bag, and a club. He was very proud of his wealth and he wanted to show off to Lord Shiva and his wife, Goddess Parvati. He invited them both over to his palace for a feast. Lord Shiva declined the offer and said that instead he could feed his son, Lord Ganesh. The king laughed, saying that he could feed thousands of children like Lord Ganesh.
Lord Ganesh turned up for the feast and was served a sumptuous meal. Ganesh continued eating steadily, showing no signs of slowing down or indicating that he had eaten enough. As was custom, the king ordered his servants to continue to serve the boy until he said that he was satisfied.
Soon the palace kitchens were empty. There was not a food left. Horrified, the king sent out his troops to the nearby villages to beg for food for his hungry guest. Whatever was given was served. Still, Lord Ganesh kept eating.
Soon there was no food left, so Lord Ganesh starting eating the furniture. Within minutes every furniture had disappeared and Lord Ganesh was still hungry.
He spoke to the king, “You promised to feed me and now there’s nothing left. I might have to eat you up!”
The king was terrified. He rushed to Lord Shiva and Goddess Parvati and begged them to save him from Lord Ganesh.
Lord Shiva then told him, “Let go of your pride and serve him a handful of rice.”
The king went back to the palace where Lord Ganesh was devouring the walls. He scraped together a handful of rice and, with great humility, personally served it to Ganesh.
Lord Ganesh’s hunger was finally appeased and the king had learned a valuable lesson.
Moral Lesson: Always remember to be humble and do not fall prey to own your pride and ego.
