In Jainism, periods (menstruation) are generally understood as a natural bodily process, not as a stain on the soul.

Key points:

• The soul is pure by nature; bodily changes do not make the soul impure.
• During menstruation, many Jain women traditionally avoid certain temple rituals, pūjā, and religious activities for a few days, mainly out of discipline, cleanliness, and tradition.
• This is usually treated as a practical observance, not a judgment of spiritual worth.
• Practices can vary by tradition, family, and community.

So, from a Jain view:

• No disrespect to the woman
• No impurity of the soul
• Some ritual restrictions may be observed temporarily

If you want, I can also explain what Jain scriptures and traditions say about temple visiting during periods.
