Answer

If you mean Porsi Pachkhan, it is a Jain morning vow in which one does not eat or drink until about one prahar after sunrise — commonly explained as roughly 3 hours after sunrise. The traditional pachhakhan text lists Porisim among the morning vows, and Jain sangh guidance often says meals during tapasya should be taken between Porsi and sunset. ( msjs.org.au)

Explanation

In simple words, Porsi Pachkhan means:

• take the vow after sunrise,
• wait until the Porsi time,
• then eat or drink only in the way allowed by that specific vow.

In many Jain traditions, it is recited with folded hands and the Navkar Mantra, as part of disciplined daily practice. ( msjs.org.au)

Spiritual Understanding

Porsi Pachkhan is a form of self-restraint and tapasya. In Jain Dharma, such vows help reduce attachment to food and support inner discipline. This is the spiritual purpose behind observing it carefully. ( msjs.org.au)

Takeaway

Porsi Pachkhan = a Jain vow to wait until Porsi time before taking food or water. It is meant to build discipline, awareness, and spiritual strength. ( msjs.org.au)
