Nirjala vrata (fast) in Jainism means fasting without any water as well as food for a whole day. “Nirjala” literally means “without water.” It is a very strict form of fasting and is observed by many Digambar Jains, especially on certain tithis or during periods of spiritual retreat. The exact practices and rules can vary between Digambar and Shwetambar communities, and between local samaj or guru traditions.

Key points:

• Nirjala means no water and no solid food for the day.
• It is undertaken on specific auspicious days or tithis, not every day.
• Digambar and Shwetambar may have small differences in how strictly the rules are applied or in the customary procedures for breaking the fast.
• It is intended as a strenuous act of self-discipline and reverence toward ahimsa (non-violence) and spiritual purification.
