Parivartini Ekadashi fast will be observed on Saturday 29 August. According to Hindu Panchang, Ekadashi of Bhadrapad Shukla Paksha is known as Charanni Ekadashi. According to religious belief, Lord Vishnu changes his sleeping posture on this Ekadashi. Changing the position changes their location, hence it is known as Parlatini Ekadashi. It is said that by observing the change of Ekadashi fast, the fast gives the same fruits as the Vajpayee Yajna. Vamana form of Vishnu is worshiped on this Ekadashi. In the Padma Purana, Shri Krishna himself has said that the Vamana form of Lord Vishnu should be worshiped on the day of Parlatini Ekadashi as the Lord resides in the Vamala form in these four months.
