Answer

If you want to continue doing upvaas the next day also, then you generally do not need to break the first upvaas and take pachkhan again.

Instead, it becomes a longer continuous fast, such as:

• 2 upvaas if you fast for two days continuously
• 3 upvaas if you fast for three days continuously
• and so on

Explanation

In Jain practice, if you have taken pachkhan for upvaas and then decide to continue fasting the next day, you can continue the same tapasya without doing parna in between.

However, it is important that your intention is clear. If the next day’s upvaas is also being undertaken, you should mentally maintain the vow of fasting and avoid any food or drink according to the type of pachkhan you have taken.

If you had taken pachkhan only for one day and later decide to extend it, it is best to ask a knowledgeable Jain guru, sadhu-sadhvi, or local scholar for the proper wording and method according to your tradition.

Spiritual Understanding

Pachkhan is not just a formality. It is a conscious spiritual resolve. The main purpose is to practice:

• self-control
• detachment from taste and body-comfort
• purification of karma
• devotion toward the soul’s upliftment

So if the upvaas continues, the inner bhaav of restraint should also continue.

Takeaway

If you are continuing the fast the next day, you normally do not break the upvaas and restart. It continues as a longer upvaas. But for the exact pachkhan method, follow the guidance of your Jain tradition or guru.
