Answer

In Jain practice, Athhai Parna should be done with proper purity, devotion, and according to your family/sampraday maryada.

If you are on the 4th day of your period, the answer may depend on the tradition followed in your home or Jain sangh. In many Jain families, women avoid certain religious rituals during menstruation, while in some places the rules may be understood differently.

So the best guidance is:

• If your family/sampraday allows Parna on the 4th day, you may do it respectfully.
• If your family follows the maryada of avoiding religious kriya during periods, then ask your Guru, Maharaj Saheb, Sadhviji, or elder for the correct way.
• Do not delay Parna in a way that harms your health. Health and proper completion of tapasya are important.

Explanation

Parna is the proper completion of fasting. After an Athhai tap, Parna is important because the body needs nourishment after long fasting.

Menstruation-related maryada is generally handled through family, sect, and Guru guidance, because practices may differ among Jain communities.

Spiritual Understanding

The main bhaav should be:

• Respect for tapasya
• Respect for maryada
• Care for the body
• Humility and guidance from Guru Bhagwant

Takeaway

Please do not risk your health after Athhai. For the religious maryada, follow your Guru/Sadhviji or family tradition. Parna should be done in the most respectful and proper way possible.
