In Jainism, practices around menstruation (periods) differ between traditions and even between families, so there isn’t a single universal rule for khamasamna and kausag during this time.

• Khamasamana (forgiveness prayer): In many households, the practice of seeking forgiveness for harmful thoughts, speech, and actions remains a part of daily practice, but some communities view the period as a time to simplify or temporarily suspend certain austere recitations or external vows. The exact handling can vary by Digambara vs. Śvetāmbara interpretation and local custom.
• Kausag (a form of discipline or purification practice): Similarly, some practitioners may adjust or pause intensive vows during menstruation, while others continue with a lighter or normal routine depending on their tradition and guidance from their guru or preceptor.

Because there are distinct rules in Digambar and Śvetāmbara traditions, and because regional or family customs also influence practice, the best approach is to consult your own guru or the specific tradition you follow to get a precise, authoritative instruction for khamasamna and kausag during your periods.

If you’d like, tell me which Jain tradition you follow (Digambara or Śvetāmbara) and your current practice level, and I can summarize the typical stance for that tradition.
