Answer

In Sthanakwasi Jain practice, brushing teeth during Ekasana is generally not done after taking the Ekasana meal, because Ekasana means eating only once in one sitting and then avoiding further intake-related activity.

If brushing is needed, it is usually done before the Ekasana meal, preferably earlier in the day.

Explanation

During Ekasana, the main discipline is:

• Eat only once.
• Eat in one place and one sitting.
• After completing the meal, do not consume anything again.

Brushing after the meal may involve:

• Water entering the mouth,
• Possibility of swallowing water,
• Disturbing the discipline of the vow.

So, many Sthanakwasi families and sadharmik people avoid brushing after Ekasana.

Spiritual Understanding

The purpose of Ekasana is not only food restriction, but also self-control, awareness, and restraint. Avoiding unnecessary mouth-related activity after the meal helps maintain the purity of the vow.

Takeaway

For Sthanakwasi Jain Ekasana, it is best to brush before the Ekasana meal, not after. For exact observance according to your family or guru-parampara, you should ask your Sthanakwasi sadhu/sadhviji or knowledgeable elder.
