Details
Nirjala Ekadashi is one of the most significant and strictest Ekadashis observed in the Hindu calendar. Falling on the 11th day (Ekadashi) of the waxing moon in the month of Jyeshtha (May–June), it is dedicated to Lord Vishnu. The term "Nirjala" means "without water," making it a highly austere fast where devotees abstain from both food and water for a full 24 hours. It is believed that observing this single Ekadashi gives the spiritual merit (punya) of all 24 Ekadashis in the year.
According to the Mahabharata, Bhima, one of the Pandavas, undertook this fast after being advised by Sage Vyasa. Devotees engage in prayers, bhajans, and reading the Vishnu Sahasranama. The vrat is believed to wash away sins, bestow salvation (moksha), and bring divine blessings. Breaking the fast (Parana) is done the next day after sunrise with tulsi water and prasad. It is considered a powerful day for spiritual cleansing and devotion.
