Answer

Yes, if you have taken Tivihar Upvas Pachkan and later decide not to drink water also, you may observe it more strictly like Chauvihar Upvas.

In Jain practice:

• Tivihar Upvas means no food, but water is allowed within the permitted time.
• Chauvihar Upvas means no food and no water.

So avoiding water is a higher level of restraint.

Important Point

Since you originally took Tivihar Pachkan, your vow was for Tivihar. By not drinking water, you are voluntarily adding more austerity. This is generally considered spiritually positive if done with:

• proper health condition,
• calm mind,
• no ego or pressure,
• and sincere bhaav.

Spiritual Understanding

In Jain Dharma, tapasya is valuable when performed with awareness, humility, and purity of intention. The purpose is not merely physical hardship, but reducing attachment to the body and strengthening self-discipline.

Takeaway

You may continue without water if your body supports it, but do it peacefully and wisely. If you are unsure, it is best to ask your Guru Maharaj, Sadhviji, or a knowledgeable Jain elder according to your tradition.
