Here are three important Jain rituals/ceremonies commonly observed:

• Samayik: A short, focused meditation and reflection, usually lasting about 48 minutes to 1 hour. The practice centers on inner discipline, concentration, and the contemplation of non-violence, truth, and other Jain vows. It is common daily or on special occasions in homes and temples.

• Pratikraman: A ritual of repentance and self-examination. Practitioners review their thoughts, speech, and actions from the day (or a specific period), confess mistakes, seek forgiveness from all beings, and resolve to avoid repeating them. It reaffirms commitment to ahimsa (non-violence) and truth.

• Paryushan (and related rituals during the festival): A major annual period of intensified austerities, reflection, and spiritual reading. During Paryushan, Jains fast or undertake limited meals, study Jain scriptures, listen to discourses, and perform additional acts of devotion and self-discipline. In many communities, it culminates in Dipawali with the "Kusumanjali" or other temple ceremonies, depending on local practice.

Notes:

• Digambar and Shwetambar communities may emphasize slightly different practices or timings for these rituals, but the core aims—self-discipline, ethical living, and spiritual purification—are the same.
• If you’d like, I can provide a concise guide for starting each practice at home or in a temple, along with common mantras or verses used in these ceremonies.
