In Sthānakvāsī (Śvetāmbara) Jain practice, menstruation is treated as a natural bodily process. The general maryādā (discipline) followed in most sanghs is:

What to pause during periods

• Do not go to the upāśraya/sabha (where pravachan, pratikraman, etc. are held).
• Do not touch scriptures, sādhu–sādhvī’s belongings, or other pavitra dravyas.
• Do not perform any ritual that involves physical handling of pavitra items or shared seating/āsan.

What you may continue

• Bhāv-bhakti at home: recite Navkār Mantra, do quiet dhyān, jap, anuprekṣā, and simple prārthanā mentally or softly.
• Listen to pravachan or svādhyāy from a distance/home (without touching granths).
• Observe small vows that don’t require contact with pavitra objects, keeping health in mind.

When to resume everything

• After three nights are over, on the 4th day, take a complete bath (śuddhi) and then you may resume regular upāśraya visits, group pratikraman, touching scriptures, etc. Some sanghs follow a 5th-day resumption; follow your local maryādā as guided by your guru.

Special notes

• If Samvatsarī or a major pratikraman falls during this time, do bhāv-pratikraman at home (mental alochanā–pratikraman–kṣamāpanā). After śuddhi, you may do an additional pratikraman if your sangh instructs.
• Cleanliness, ahiṁsā, and inner purity are primary. Menstruation does not stop inner sādhanā; only certain external contacts are paused.

Difference in traditions

• Śvetāmbara Sthānakvāsī: as above (no idol-worship anyway, so the focus is on upāśraya, scriptures, and pavitra dravyas).
• Digambara: broadly similar sentiment—pause physical/ritual contact with pavitra objects during menstruation; mental sādhanā is allowed. Exact rules can vary by ācārya’s maryādā.

Because local customs can differ by sangh and guru, please follow the maryādā you have received from your own ācārya/sādhvī.
