Answer

Yes, generally one may drink water after Pratikraman.

Explanation

Pratikraman is a sacred practice of repentance, reflection, forgiveness, and spiritual purification. After completing Pratikraman, drinking water is not prohibited in the general Jain household practice.

However, it depends on the context:

• If you are observing a specific vow, fast, or tapasya, then you should follow the rules of that vow.
• If it is after sunset, many Jains avoid drinking water as part of chauvihar or night-abstinence discipline.
• If your family, sect, guru, or local tradition has a specific rule, it is best to follow that guidance.

Spiritual Understanding

The purpose of Pratikraman is inner purification. Drinking water after it does not reduce its spiritual value, unless it breaks a vow you have taken.

Takeaway

You can drink water after Pratikraman, unless you are observing chauvihar, fasting, or another specific Jain discipline that restricts it.
