Here is a simple, authentic Jain way to observe Diwali (Mahavira Nirvana Kalyanak) and do a Diwali pooja:

• Purpose

- Remember Mahavira’s Nirvana (liberation) and the light of true knowledge. It is a time for inner reflection, ahimsa, and spiritual renewal.

• Common domestic pooja (upa-puja)

- Light a diya or lamp to symbolize the light of knowledge. - Offer prayers to Mahavira (and, if desired, to Gautam Swami and other Tirthankaras). - Read or recite brief Jain prayers or verses, such as parts of the Uttaradhyayana Sutra or simple Namokar Mantra. - Make a small offering (flowers, fruit, sweets) as a symbolic welcome of auspiciousness. - Keep the environment calm and peaceful; focus on inner light rather than external show.

• Additional practices (personal devotion)

- Do a short Samayik (mindful meditation) or Pratikraman (self-reflection and seeking forgiveness) during the Diwali period. - Engage in charity (dana) and acts of kindness. - Reflect on non-violence (ahimsa) in daily life; avoid harm to living beings (e.g., limit or avoid loud firecrackers).

• Fasting and scripture

- Some devotees perform a brief fast or partial fasting, and read or listen to short Jain scriptures about Mahavira’s teachings.

• Differences between Digambar and Shwetambar

- The core meaning remains the same: Mahavira’s Nirvana is honored, and Guruvandana is expressed. - The exact format, prayers, and chosen scriptures may vary slightly between Digambar and Shwetambar communities. Both celebrate with lamps, remembrance of Mahavira, and devotions, but the details of ritual steps can differ.

• Practical notes for 2025

- Main Diwali day in 2025 is around October 20–21, with Lakshmi Puja commonly observed on the evening of October 20. Regional calendars may vary by a day or two.
