Story of Shwetaki
King Shwetaki was an illustrious and pious King. He wanted to perform a Yagna - the likes of which was never done before. But all the Rishis refused to help him perform this sacrifice. Then, on the advice of Bhagwan Shiv the King approached Rishi Durvasa for help. The Yagna went on for 12 years where a continuous stream of Ghee was poured into the fire. This excess consumption of Ghee made Agni Dev lazy. Agni Dev regained his strength after he consumed the entire Khandavprasth forest.
