Diwali is celebrated by Jains mainly to honor the nirvana (liberation) of Lord Mahavira. It is seen as the day when his earthly life ended and his soul attained ultimate enlightenment, and it is also a time to remind ourselves of his teachings—truth, non-violence, and self-discipline.

Key points:

• Why on Diwali: Mahavira attained Nirvana on the dark half of Kartik (often described as the night of Amavasya), and lamps are lit to symbolize the light of knowledge dispelling ignorance. This marks the end of the monsoon retreat and a time for spiritual reflection and renewal. ( jainknowledge.com)
• How Jains observe: many light lamps, recite passages from Jain scriptures (especially prayers around Mahavira), fast or observe restraint, perform charitable acts, and avoid firecrackers to keep the celebration peaceful and mindful. Temples and homes are decorated with lights as a symbol of wisdom and the removal of darkness. ( jainknowledge.com)
• Timing and tradition differences: while the core meaning is the same, the emphasis can vary by Digambara and Śvētāmbara communities. Some observe three days of fasting or special puja; others highlight the awakening of Mahavira’s disciples and the teaching tradition that followed. The common thread is simplicity, compassion, and self-purification. ( timesofindia.indiatimes.com)
