Answer

Yes, in Jain practice, you may brush after sunrise before doing parna, as long as you are careful about Jain principles such as ahimsa and the rules of the particular tapasya you are observing.

Explanation

Parna means formally ending a fast by taking food or water at the proper time, usually after sunrise and according to the prescribed time.

Brushing before parna is generally treated as cleaning the mouth, not as breaking the fast, provided that:

• You do not swallow water or toothpaste.
• You avoid unnecessary use of water.
• You are careful not to harm living beings as much as possible.
• You follow the guidance of your family tradition, guru, or local Jain sangh.

Some stricter observers may avoid brushing before parna and may only rinse carefully, depending on the type of fast and their tradition.

Spiritual Understanding

In Jain Dharma, fasting is not only about avoiding food. It is also about awareness, restraint, purity, and reducing harm. So the main point is to maintain discipline and avoid carelessness.

Takeaway

You can brush after sunrise before parna, but do it carefully and do not swallow anything. For strict tapasya rules, follow your guru or sangh’s guidance.
