Nirjala Ekadashi is being celebrated on June 13. Devotees observe fast on this day. They neither eat nor drink water for the entire day. They pray to Lord Vishnu. Nirjala Ekadashi, also called Bhima Ekadashi, is the biggest and most significant of all 24 ekadashis observed in the year. Nirjala Ekadashi falls immediately after Ganga Dussehra.
