Prabodini Ekadashi, or Dev Uthani Ekadasi, is observed on the eleventh day during the Shukla Paksha or waxing phase of moon in Kartik Month as per traditional Hindu Lunar Calendar. Lord Vishnu who was in a deep slumber during the Chaturmas period wakes up on the day. An interesting story associated with Prabodini Ekadashi is listened to on the day. There are several versions of Dev Uthani Ekadasi Vrat Katha this is one of them. Legend has it that Goddess Lakshmi, the consort of Lord Vishnu, was unhappy with manner in which Lord Vishnu slept. Sometimes Lord Vishnu used to remain awake for days together and sometimes would sleep continuously for several days. Goddess Lakshmi then complained to Lord Vishnu about his undisciplined way of sleeping. She said that Lord Shiva, Lord Brahma, Devas and Saints visiting him are forced to wait for long period as He is sleeping for several days together. They are forced to return disappointed without having the Darshan of Lord Vishnu.
