Answer

In Jain Dharma, during Paryushan, drinking water is generally allowed only during the permitted daytime period, depending on the vow or tapasya you are observing.

Most importantly:

• Boiled water is traditionally used.
• Water is generally avoided after sunset and before sunrise.
• If you are doing a specific fast like Upvas, Chauvihar, Tivihar, or Ayambil, the rule depends on that vow.

Explanation

Common practices are:

• Normal Paryushan observance: You may drink boiled water during the day, within the allowed time.
• Chauvihar: No food or water after sunset.
• Tivihar: Food is avoided, but boiled water may be allowed during the permitted time.
• Upvas: Depending on your vow, you may take boiled water during the day, or you may observe complete fasting without water.

Rules can vary by Jain tradition, family practice, and the specific vow taken.

Spiritual Understanding

The purpose is not just restriction, but increasing self-discipline, awareness, and ahimsa. Boiled water and time restrictions are connected with minimizing harm to living beings and controlling desires.

Takeaway

You should not drink water “anytime” during Paryushan. Drink only according to your vow, preferably boiled water during the permitted daytime period, and follow the guidance of your guru, family tradition, or local sangh.
