Short answer: Do pratikraman. If touching a book is a concern in your tradition, do it without touching, or do bhāv-pratikraman (mental recitation). Details below.

• Core Jain view (for śrāvikās): Menstruation is a natural bodily state. The heart of pratikraman is inner repentance, restraint, and right resolve (bhāva–pradhānya). If physical handling of sacred items is restricted by your maryādā, you can still fully do pratikraman mentally at home.

• Śvetāmbara practice (general community maryādā today): Many allow women to perform samayik and pratikraman during periods at home. If you do not know it by heart, you may read from your own copy, kept clean and separate. Prefer placing the book on a stand/cloth and turning pages with a clean cloth; avoid taking it to a temple or shared library during this time.

• Digambara practice (traditional maryādā): Often advises avoiding touching idols and scriptures during menstruation. In such settings, do bhāv‑pratikraman: listen to an audio, softly repeat from memory, or read without direct hand contact (book on a stand, pages turned with a cloth). The emphasis remains on sincere alochanā, kṣamā-yācanā, and resolve to refrain from faults.

Practical, respectful options

• Best: bhāv‑pratikraman or listening and repeating, without handling a text.
• If your sect’s/local maryādā permits: read at home from your own book, keep it separate and clean, use a bookstand/cloth, maintain personal hygiene, and refrain from temple handling.

If your family saṃpradāya has a specific rule, follow that maryādā. In all cases, sincerity of repentance and right conduct is what makes pratikraman fruitful.
