Answer

During Porsi, a person generally eats once in the day, after completing the Porsi time period.

Explanation

Porsi is a Jain tapasya in which one does not eat for a fixed period after sunrise. After that period is completed, the person may take food according to the rules they have accepted.

In common Jain practice, Porsi is understood as eating only after the Porsi time is over, and many people take one proper meal for the day as part of the discipline.

Spiritual Understanding

The purpose of Porsi is not only reducing food, but developing:

• Control over taste and desire
• Discipline of the body and mind
• Awareness in eating
• Progress in self-restraint

Takeaway

For Porsi, the usual disciplined practice is to eat once in the day after the Porsi period is completed. If you are following a specific tradition, family rule, or guidance from a Guru Maharaj/Sadhviji, follow that instruction.
