Answer

In Jain Dharma, whether you can take water during upwas depends on the type of fast and the tradition you are following.

• Chauvihar Upwas: No food and no water.
• Tivihar Upwas: No food, but boiled water may be taken during the permitted time.

Explanation

In many Jain traditions, water during upwas is allowed only if it is boiled and cooled, and taken only during the proper daytime period. After sunset, water is generally avoided, especially in chauvihar.

If you have taken a specific vow of chauvihar upwas, then water should not be taken. If it is tivihar upwas, boiled water may be allowed.

Takeaway

Please follow the rule of the upwas you have taken and the guidance of your guru, family tradition, or Jain sangh. If your health is weak, it is better to ask a knowledgeable elder or doctor before fasting strictly.
