Nirjala Ekadashi

Vidhi. The strict form is without water from sunrise to the next sunrise. Elderly and ill families often keep phalahar instead — that is a household choice, not a panchang command.

Paran. Paran after Nirjala ends the next morning. Drink water first, then a light meal, after checking tithi end.

Mantra. Om Namo Bhagavate Vasudevaya

Also called Bhimseni Ekadashi. Merit is described as equal to all twenty-four ekadashis — that is tradition, not a medical claim.
