Answer

During Paryushan, boiled water is generally used only within its valid kāl (time limit) according to Jain practice.

The common traditional guideline is:

• Daytime boiled water: usable until the end of the same day, before sunset.
• Night-time use: water should not be consumed after sunset in stricter Jain practice.
• Next day: boiled water from the previous day is not normally used.

Explanation

In Jain Dharma, water is boiled to reduce harm to living beings present in water. But after some time, new microscopic life may again develop, so boiled water has a limited valid period.

During Paryushan, many people follow this more strictly by:

• Boiling fresh water daily
• Filtering it properly
• Using it only during the proper time
• Avoiding water after sunset, if following stricter practice

Important Note

The exact boiled water kāl timing can vary by Jain tradition, sect, local sangh practice, and guidance of Guru Bhagwant.

So for Paryushan, it is best to follow the rule given by your Guru Maharaj, Upashray, Derasar, or local Sangh.

Takeaway

During Paryushan, the safest traditional approach is: boil fresh water daily, use it before sunset, and follow your Guru’s guidance.
