Answer

Yes, during upavas one may generally take bath and may also do Abhishek, according to common Jain practice.

Explanation

In Jain Dharma, upavas mainly means giving up food and maintaining spiritual discipline. Taking bath is not considered breaking the fast.

Many people take bath before doing:

• Dev Darshan
• Abhishek
• Puja
• Samayik
• Pratikraman

So, if your health permits and it is part of your daily religious practice, you may bathe and perform Abhishek with devotion.

Spiritual Understanding

During upavas, the main focus should be on:

• Reducing attachment to the body
• Controlling passions
• Doing japa, swadhyay, samayik, pratikraman
• Maintaining purity of mind, speech, and action

Bath and Abhishek should be done with humility and devotion, not for comfort, luxury, or bodily decoration.

Takeaway

Taking bath and doing Abhishek during upavas is generally allowed, but follow the maryada of your Jain tradition, temple, and guru’s guidance.
