Answer

Yes, if you boiled the water at 8:00 am, it is generally considered usable during the day for your upvas, according to common Jain practice.

Explanation

In Jain practice, boiled water is used because boiling helps reduce living organisms in water.

A common rule followed is:

• Boiled water during daytime may be used until sunset.
• After sunset, many Jains do not drink water during upvas or follow stricter rules depending on their vow.

So if it is still before sunset, and the water was properly boiled and kept covered, you may drink it if your upvas allows boiled water.

Important

Different families, sanghs, and traditions may follow slightly different rules. If your upvas is under a specific niyam, tapasya, or guru’s guidance, follow that instruction.

Takeaway

Boiled water from 8:00 am is generally usable until sunset, if kept clean and covered, and if your upvas permits water.
