Answer

In Jain practice, there is no single universal kriya for every tradition, but commonly before parna after upvas, one does:

• Navkar Mantra jaap
• Kshamapana / Michhami Dukkadam
• Darshan and vandan to Paramatma, Guru, or the place of worship
• If your vrat tradition requires it, a short pratikraman or prayer
• Then parna is done at the proper time, as prescribed

Explanation

The main intention before parna is to end the fast with:

• bhakti
• vinay
• kshama
• shuddha bhavna

Many people also avoid rushing into food immediately. They first remain शांत, do namaskar, and then break the upvas in a disciplined way.

Because Jain fasting methods can differ by sampraday, guru-parampara, and the type of upvas, the exact kriya may vary.

Spiritual Understanding

Before parna, the mind should stay in a state of:

• gratitude
• humility
• forgiveness
• inner purity

This keeps the upvas not only as a physical discipline, but also as a spiritual tapa.

Takeaway

A simple Jain way before parna is:

Navkar Mantra → Michhami Dukkadam → darshan/vandan → parna
