Answer

Yes, during Beasana you may take a bath.

Explanation

Beasana means taking food only two times in a day, usually within proper Jain discipline and time limits. Bathing is not considered a break of Beasana.

However:

• Take bath in a careful and gentle way.
• Avoid unnecessary wastage of water.
• Maintain awareness of Ahimsa.
• Follow the guidance of your family tradition, Guru, or Jain Sangh if they observe any specific rule.

Spiritual Understanding

The main purpose of Beasana is self-control over food and senses. Bathing for cleanliness does not disturb the vow, as long as it is done with care and restraint.

Takeaway

You can take bath while doing Beasana, but observe simplicity, carefulness, and Ahimsa.
