Answer

In many Jain traditions, water for use should be boiled and handled according to the local maryada, and some traditions prefer it to be prepared before sunrise. So after sunrise, it is not a universal rule that first water can be boiled. It depends on your sampradaya, guru’s guidance, and local Jain practice.

Explanation

During Chaumasa, Jain care for water is very strict because of increased possibility of small living beings in water. So the practice may differ like this:

• Some traditions allow boiling at a certain time as per their maryada.
• Some traditions prefer boiling before sunrise only.
• Some families follow the guidance of their sadhus/sadhvis or local mandal.

So the safest answer is: follow the rule of your Jain tradition, not a general assumption.

Spiritual Understanding

The purpose is ahimsa and carefulness in daily life. In Jain Dharma, even small details like water use are treated with mindfulness, purity, and restraint.

Takeaway

If you are unsure, ask your local Jain guru or mandal and follow the established maryada of your tradition. There is no single rule accepted by all Jains for this.
