Chaityavandan is a part of the Paryushan observances and is commonly included on the last day (Samvatsari) as a devotion at the chaitya (temple/derasar) and during the Pratikraman. On the final day, Jains focus on forgiveness (Kshama) and reflection, and Chaityavandan is performed as a devotional offering to the Tirthankaras and the sacred places, often alongside the formal Samvatsari Pratikraman and the recitation of the MIchhami Dukkaḍaṃ (forgiveness).

Key points you can remember:

• The last day of Paryushan is Samvatsari in many Śvetāmbara communities (forgiveness day). It centers on confession, forgiveness, and deep introspection.
• Chaityavandan is commonly included as part of the day’s temple prayers and pratikraman, helping a devotee express reverence for the Tirthankaras and seek inner purification.
• Digambar communities observe Das Lakshana Parva (often 10 days) starting after the main Samvatsari; the first day of that sequence is also centered on Kshamā (forgiveness), but the overall calendar and sequence differ from Śvetāmbara practice. The spiritual aim remains repentance, humility, and harmony with all beings.

If you’d like, I can share a simple, traditional wording of Chaityavandan and outline how it fits into the Samvatsari pratikraman, with distinctions between Digambar and Śvetāmbara practices.
