Yes. Paryushan Parva is a major Jain festival, and it culminates on the last day with Samvatsari Pratikraman in many communities.

What to do on the last day (Samvatsari) and around this time:

• Perform Pratikraman (repentance and reflection): systematically recall your thoughts, words, and actions that may have harmed others, and seek forgiveness.
• Say “Micchami Dammami” (I seek forgiveness) to all living beings you may have harmed, directly or indirectly.
• Do a Samayika (meditative, scriptural session) for about 30–45 minutes, focusing on mindfulness, non-violence, truth, and non-possessiveness.
• Observe a vow or fast as you are able (many people do a day-long fast or a partial fasting combined with prayers).
• Read or listen to Jain scriptures or prayers, especially those that remind you of moral conduct, non-violence (ahimsa), truth (satya), and detachment (aparigraha).
• Practice ahimsa in daily life: gentler speech, kindness to others, and restraint in harmful actions or words.
• If you can, visit a temple or attend a community gathering for collective prayers and sermons.
• Give charity or help those in need as an expression of compassion and self-purification.

Important notes:

• There is a difference between Digambar and Shwetambar communities on the exact length of Paryushan (some observe 8 days, some 10 days) and on certain practices. The core essence remains: sincere repentance, forgiveness, and spiritual refreshment.
• Even if you cannot do a full Pratikraman, you can still do a shorter reflection, offer apologies to those you’ve wronged, practice restraint, and engage in peaceful, mindful activities.

If you’d like, tell me which Jain tradition you follow (Digambar or Shwetambar) and your current situation (time, health, etc.), and I can tailor a simple, personal plan for today.
