Answer

If boiled water was completed at 7:15 AM, then its kāl is generally counted for one prahar, which is about 3 hours.

So the boiled water may be used until approximately:

10:15 AM

Explanation

In Jain practice, boiled water is used to reduce harm to subtle living beings in water. After boiling, it is considered suitable only for a limited period.

The commonly followed rule is:

• Boiled water kāl = about 3 hours
• If boiled at 7:15 AM
• Then its time limit is until 10:15 AM

Takeaway

Use the boiled water before 10:15 AM. After that, according to Jain practice, it should not be used for drinking.
