Answer

Yes. In a Tivihar Pachkhan, water is generally allowed after sunset and at night, because Tivihar means renouncing three types of intake:

• Food
• Liquids other than water
• Certain consumable items

Water is not renounced in Tivihar. So, if you have taken Tivihar Pachkhan, you may drink water after 12 at night, provided it is acceptable according to your family/gachchh tradition and the specific Pachkhan you took.

Explanation

In Jain practice:

• Tivihar usually means you give up all food and drinks except water.
• Chauvihar means you give up both food and water.

So if your Pachkhan was specifically Tivihar, drinking water is normally permitted.

Important Note

If the Pachkhan was taken with a specific time limit or special condition given by a guru, sadhu, sadhvi, or elder, then you should follow that instruction exactly.

Takeaway

Tivihar = water allowed.
Chauvihar = water not allowed.
