Story of King Ambarisha is part of many Puranas and it explains the greatness of Ekadashi fasting. The story teaches us the importance and rewards of devotion and the folly of jealousy and unchecked anger. King Ambarisha was an ardent devotee of Hindu God Vishnu and performed the Ekadasi fasting without a break. Pleased with his devotion and piety, Vishnu honored him with the ability to control Sudarshana Chakra. The Story of Ambarisha is that of jealous Indra using Durvasa Maharishi to put an end to the Ekadasi fasting of King Ambarisha. Indra felt threatened by the piety by King Ambarisha. He instigated Durvasa Maharishi against King Ambarisha. Durvasa arrived at the palace of King Ambarisha when he was about to break his Ekadasi fasting. He was received warmly by the king. Rishi was invited for taking food. The Rishi then went to take bath in the Kalindi River and for his prayers. Durvasa deliberately took longer time to spoil the Ekadasi fasting of King Ambaris
