Parsva Ekadashi is also known as Vamana Ekadashi, Jaljhilini Ekadashi and Parivartini Ekadashi. It is observed with great enthusiasm all over India. According to Hindu mythology, it is believed that during this period, Lord Vishnu rests and changes his sleeping position to the right side from the left. Therefore, it is called Parsva Parivartini Ekadashi.
