Answer

In Jain Dharma, 3 days upvas, then one day parna, and again 4 days upvas is generally called Atthai Tap.

Explanation

Atthai means a tapasya connected with 8 days of fasting discipline. In practice, some people complete it as:

• 8 continuous upvas, or
• 3 upvas + parna + 4 upvas, depending on health, strength, and guidance.

Since there is one parna in between, people may describe it as Atthai with parna in between, but commonly it is still understood as part of Atthai Tap.

Spiritual Understanding

The value of tapasya is not only in the number of fasting days, but in doing it with:

• Samyak bhav
• Inner purity
• Ahimsa
• Forgiveness
• Control over desires
• Devotion to the soul’s upliftment

Takeaway

It is commonly known as Atthai Tap, especially if done with the intention of completing an 8-day tapasya.
