According to Hindu mythology, Narada had once given a ripe mango to Lord Shiva and requested him to consume it without slicing it. Parvati wanted to give the mango to her children, Ganesh and Karthik. But since the mango could be eaten by only one of them due to Narada’s condition, a competition was arranged between Ganesha and Karthik. It was decided that whosoever wins the condition would get the mango. Ganesha won the contest by using his intelligence. This angered Karthik and he left his abode and settled on a mountain top. The rest of the story revolves around how Parvati pacifies Karthik by narrating to him the stories of Lord Shiva. There are four stories in all. At the end of the fourth story, Karthik is pacified and he comes back.
