Chaityavandan is a significant daily ritual in Jainism, involving prayers and reverence to the Tirthankaras and the Jain temple (chaitya). During Paryushan—the most important annual festival for Jains—performing Chaityavandan gains special importance.

Chaityavandan during Paryushan:

1. Increased Devotion: Jains are encouraged to perform Chaityavandan with greater devotion and regularity during Paryushan. Many observe it both in the morning and evening, sometimes with group participation at the temple.

1. Procedure: The ritual involves recitation of various sutras, including Namokar Mantra, Khamasaman, and Pratikraman-related prayers. The focus is on repentance, forgiveness, and spiritual upliftment, which align with the themes of Paryushan.

1. Special Sutras: During Paryushan, some additional sutras or longer versions of Chaityavandan may be recited, such as Logassa Sutra, Chattari Mangalam, and others, as guided by Jain scriptures and traditions.

1. Austerity and Purity: Practitioners observe greater austerity and internal purity during Paryushan, so Chaityavandan is performed with increased mindfulness, wearing clean clothes, and observing proper rituals.

1. Collective Prayers: In many Jain communities, collective Chaityavandan is organized in temples, fostering a sense of unity and shared spiritual endeavor.

Purpose:

• To purify the mind and soul.
• To express gratitude and seek guidance from Tirthankaras.
• To reinforce the values of ahimsa (non-violence), satya (truth), and forgiveness, which are emphasized during Paryushan.

Summary: During Paryushan, performing Chaityavandan is considered highly meritorious and integral to the observance, helping Jains focus on spiritual purification, self-discipline, and forgiveness.
