In Jainism, Nigod Nivaran Tap is an austerity observed with the intention of liberating souls from the Nigod state (the lowest form of existence with minimal consciousness). This special austerity is associated with the Paryushan and other periods of intensified spiritual practice.

The typical structure of Nigod Nivaran Tap includes a combination of Upvas (complete fasts) and Ekashana (one meal a day). The commonly observed format is:

• 3 Upvas (complete fasting for three days)
• 4 Ekashana (one meal per day for four days)

Total: It is a 7-day austerity: 3 days Upvas + 4 days Ekashana

Note: Some variations may exist based on sect or local tradition, but the above (3 Upvas + 4 Ekashana) is the most widely practiced form.
