Navkārśī time in Jain Dharma is the time after sunrise, when one can take boiled water with Navkār mantra remembrance and then later take food according to the vow or practice.

In common usage:

• Navkārśī = one may consume boiled water only after sunrise, after a fixed waiting period.
• It is generally observed 48 minutes after sunrise.
• During this time, one remembers the Navkār Mantra before beginning water intake.

This is a respected Jain practice connected with discipline, purity, and self-control.

If you want, I can also explain:

• Navkārśī vs Porsi vs Sāymuthhi, or
• the exact timing calculation in simple terms.
