Avakraman is not a standard, widely-attested term in Jain scriptures. If you meant a related idea, the most common Jain concepts are:

• Pratikraman (प्रतिक्रमण): a formal practice of introspection, confession, and vow-renewal to return to right conduct. It literally means “returning” or “going back” from transgressions. It is done to purify the soul and lessen karmic bondage, often in daily life and on special days (twice daily, fortnightly, four-monthly, or annually during Samvatsari). There are differences in practice between Śvetāmbara and Digambara traditions, but the core aim—repentance and recommitment—remains the same. You can read more here

• Āvaśyaka (आवश्यक): the six essential daily practices that structure Jain discipline; pratikraman is the fourth among them. For a concise overview of these essentials, see the related Jain Knowledge notes here

If you had a different spelling or a specific source in mind (Digambar vs. Śvetāmbara texts), tell me which one, and I’ll explain precisely as per that tradition.
