Answer

If you mean Navanu Tap / Navanu fasting, there is usually no formal “application” in Jain Dharma. You normally take a sankalp and begin it with proper guidance from a sadhu, sadhvi, or your local Jain sangh/temple.

Explanation

To observe Navanu properly, you can follow these steps:

• Speak to your guru or temple committee if the Navanu is being done as part of a group or organized tapa.
• Take a firm sankalp: decide that you will observe it with sincerity and discipline.
• Understand the rules clearly: the method can vary by tradition and local practice.
• Prepare mentally and physically: keep the intention pure, peaceful, and detached.
• Follow the needed fasting or diet rules exactly as advised in your Jain tradition.
• Do pratikraman, samayik, swadhyay, and bhakti as part of the tapasya, if possible.
• Complete it with humility and thanksgiving, not pride.

If your sangh organizes Navanu, they may ask you to register your name or inform them in advance. That is the closest thing to an “application.”

Spiritual Understanding

In Jain Dharma, tapasya is not just about the outer vow. It is about:

• Self-control
• Purification of karma
• Inner discipline
• Humility and devotion

The real value of Navanu comes from right intention, right guidance, and sincerity.

Takeaway

In short: there is usually no official application for Navanu in Jainism. You should inform your local Jain temple, sangh, or guru, take a proper sankalp, and begin with reverence and discipline.

If no organized process exists in your area, simply doing it with the right Jain विधि and sincere intention is enough.
