Short answer: Yes, you can do pratikraman during menstruation, but many communities observe it in a simplified, non-ritual, inner form (bhāva-pratikraman). The key is that the inner intention to purify and refrain from harm remains the same; the restrictions are about ritual handling of sacred objects and certain activities, not about the soul’s purity.

What to generally observe (maryādā) during periods

• Do not touch mūrtis, pūjā-dravya, or sacred texts, and avoid entering temples or performing certain temple rituals.
• You may refrain from intense fasting or new vrats; you can rest and keep personal hygiene strict.
• Practicing bhāva-pratikraman (inner repentance) is encouraged, even if you don’t touch ritual items. If allowed by your sangh, you may recite or listen to pratikraman in a non-ritual manner, focusing on reflection, confession (ālochana), and resolve (pratyākhyān).
• After the period ends and you take a full bath, you may resume normal temple/ritual activities.

Important clarifications

• In Jain Dharma, menstruation does not make the soul impure. The restrictions are ritual-purity rules to protect sacred objects and for practical rest. The inner aim of pratikraman—reducing harm and purifying the mind—remains intact during this time. Digambar and Śvetāmbara traditions both generally permit bhāva-pratikraman during rajsvālā (menstruation), with differences mainly in how strictly they limit touching ritual objects.

• Pratikraman itself is about introspection and pleading for forgiveness for lapses in the 12 vows. The practice can be done in a non-ritual, mental form when ritual activities are restricted. ( jainknowledge.com)

Simple, practical outline for bhāva-pratikraman during periods

• Sit in quiet at home or in a calm space.
• Do bhāva-pratikraman: recall faults, offer remorse, and make firm resolutions to avoid repeating them (pratyākhyān).
• If listening to a pravachan or following along is allowed, do so without handling sacred objects.
• Maintain cleanliness and gentle, mindful conduct; rest as needed.

If you want a brief, step-by-step mental framework to follow, you can use: samayik bhāva (calm, balanced state), ālochana (confession of faults), pratyākhyān (resolve to avoid them), kṣamāpanā (seeking forgiveness), and maitri-bhāvanā (loving-kindness). This aligns with the core purpose of pratikraman while respecting maryādā.
