Answer

After completing Atthai tapasya, many Jains do Parna on the next day.

Parna means respectfully breaking the fast in a proper and disciplined way.

Explanation

In Jain tradition, Parna after Atthai is usually done with:

• Devotional feeling and gratitude
• Simple, suitable food or drink
• Careful timing, usually after sunrise and according to proper local Jain practice
• Calmness and self-control, not overeating after the fast

Commonly, people may start with items considered suitable for Parna in their family or sangh tradition. The exact method can vary by Jain tradition, local custom, health condition, and guidance of a Guru or senior shravak/shravika.

Spiritual Understanding

Atthai is not only physical fasting; it is meant for purification of the soul through restraint, repentance, devotion, and reduction of attachment.

Parna should also be done with the same spirit:

• Without pride
• Without greed for taste
• With humility
• With remembrance of the soul’s spiritual goal

Takeaway

After Atthai, do Parna gently, respectfully, and according to your Jain tradition, preferably with guidance from your Guru, family elders, or local sangh.
