Answer

Yes, generally Navkarsi can still be done if you drank water in the middle of the night, as long as you observe the Navkarsi rule from sunrise onward.

In Jain practice, Navkarsi means taking food or drink only after approximately 48 minutes after sunrise.

Explanation

If water was taken during the night, before sunrise, it does not usually cancel Navkarsi, because the main discipline of Navkarsi is connected with not eating or drinking from sunrise until the Navkarsi time.

So:

• If you drank water at night and then did not consume anything after sunrise until Navkarsi time, you may do Navkarsi.
• If you drank water after sunrise before Navkarsi time, then Navkarsi would not be considered properly observed.

Spiritual Understanding

Navkarsi is a small but meaningful form of self-discipline. Its purpose is to develop restraint, awareness, and control over taste and habit.

Takeaway

Drinking water in the middle of the night does not normally prevent Navkarsi, provided you maintain the vow properly after sunrise. For stricter observance, follow the guidance of your guru or local Jain tradition.
