Answer

In Jain practice, boiled water is generally considered usable for 24 hours after boiling.

After 24 hours, it is traditionally not used as “boiled water” for Jain religious discipline.

Explanation

In Jain Dharma, boiling water is practiced to reduce harm to tiny living beings present in water. However, after some time, new microorganisms may again develop or enter the water.

So, traditionally:

• Boiled water: usable for about 24 hours
• After that, it should be boiled again if needed

Some families or sects may follow stricter timing depending on their tradition, especially during tapasya, pratikraman, or special religious observances.

Takeaway

For general Jain practice, remember: boiled water is valid for 24 hours, and after that it should be re-boiled or avoided according to one’s discipline.
