Answer

In Jain practice, boiled water prepared before 9:00 AM is generally used only until sunset of the same day.

After sunset, it should not be used for drinking.

Explanation

According to Jain discipline, water is boiled to reduce living organisms in it. But after some time, life forms may again begin to develop in the water. Therefore, boiled water is not kept indefinitely.

A common Jain household practice is:

• Boiled during daytime: drink until sunset.
• Not used after sunset: especially by those following stricter Jain rules.

Some traditions and families follow more specific timing rules, so it is best to follow the guidance of your guru, sangh, or family tradition.

Takeaway

If water was boiled before 9:00 AM, the safe Jain practice is to drink it only until sunset that day.
