Answer

If you want to do Navkarsi, then you should stop drinking water before sunrise.

In the common Jain practice, water is taken only after sunrise, and in many traditions after about 48 minutes past sunrise and after reciting the Navkar Mantra.

Explanation

• Before sunrise: no water, if you are observing Navkarsi.
• After sunrise: water may be taken according to the rule followed in your tradition.
• The exact practice can vary slightly between Jain traditions and local customs.

Spiritual Understanding

Navkarsi is a practice of discipline and mindfulness. It helps one begin the day with:

• self-control
• purity of intention
• remembrance of the Navkar Mantra

Takeaway

For a simple rule: do not drink water after sunrise if you are keeping Navkarsi, unless your tradition specifically allows it after the Navkarsi time.
