Answer

A commonly used sangh listing shows Nigod Nivaran Tap as 25 upvas. In the sources I could verify, I did not find one universally fixed step-by-step vidhi/format; it appears to be observed according to the sangh or guru’s guidance. ( jaincenterus.org)

Explanation

If you want a simple writing format for announcement or bahuman, you can use:

• Name
• Tapascharya: Nigod Nivaran Tap
• Total: 25 Upvas

Example: Shri/Smt. ________ — Nigod Nivaran Tap — 25 Upvas

Spiritual Understanding

In Jain Dharma, such tapas is done for atma-shuddhi, karma-nirjara, and anumodana. The exact outward pattern may vary, but the inner bhavna should remain pure, humble, and devoted. ( jaincenterus.org)

Takeaway

For a practical format, write it as “Nigod Nivaran Tap – 25 Upvas.” If you need, I can also give you a Gujarati announcement format for tapascharya.
