Answer

Yes, in common Jain practice, while doing biasana, you may drink water before the first meal, if it is part of your accepted niyam and the water is properly filtered/boiled according to your tradition.

Explanation

Biasana generally means taking food only two times in the day. Drinking water is usually not counted as a full meal, but practices can vary depending on:

• Family tradition
• Sect or sampraday practice
• The exact niyam you have taken
• Whether you are doing ordinary biasana or a stricter tapasya

If your niyam is simply “I will eat only two times”, then drinking water before the first meal is generally allowed.

But if you have taken a stricter vow such as not taking anything before the first meal, then you should follow that vow.

Spiritual Understanding

In Jain Dharma, tapasya is not only about the outer rule but also about self-control, awareness, and reduction of attachment. So water should be taken mindfully, not casually or repeatedly without need.

Takeaway

For normal biasana, drinking water before the first meal is generally acceptable, but follow the specific niyam given by your guru, family elder, or tradition.
