Answer

In Jain practice, boiled water is generally considered acceptable for a limited time after boiling, depending on the tradition followed.

For Tivihar Upvas, if the water was boiled at 7:00 AM, then it should be consumed only within the permitted time followed in your sampraday or family tradition.

Commonly, many Jains follow:

• Daytime limit: boiled water may be used until sunset of the same day.
• Some traditions follow a stricter fixed-hour rule, such as using it within a few hours after boiling.

Explanation

In Tivihar Upvas, one gives up food but may take boiled water during the permitted time. The purpose of boiling water is to reduce harm to living beings in water.

However, after some time, water is considered unsuitable because new subtle life may begin to develop again. That is why boiled water is not kept indefinitely.

Takeaway

If boiled at 7:00 AM, many Jains would use it until sunset the same day, but you should follow the exact rule given by your Guru Bhagwant, sampraday, or family tradition, because practices can differ respectfully among Jain traditions.
