Jain dharma does not prescribe a standard vidhi (ritual) for Lakshmi puja. Lakshmi is a Hindu goddess associated with wealth, and Lakshmi puja is not part of Jain puja or liturgical practice.

In Jainism, wealth and prosperity are viewed as results of right conduct and spiritual progress. The emphasis is on purifying the soul through right view (samyak darshan), right belief, and righteous actions (ahimsa, satya, asteya, brahmacharya, aparigraha), rather than invoking a deity for material blessings.

If a Jain family wishes to observe religious practices, they typically focus on:

• Worship of Tirthankaras and revered Jain figures (e.g., Mahavira) in a temple or home shrine.
• Observances like samayik, rituals of purification, and daily prayers (pratikraman, mangalarthi, vandana).
• Charity and charitable acts as a means to cultivate optimism and merit, rather than worship of wealth personified.

Some Jain households may light lamps during festivals like Diwali as a cultural practice, but this is usually framed as symbolic illumination of the soul and a remembrance of Jain values, not as Lakshmi worship.

If you’d like, I can help find a JainKnowledge.com page that discusses how Jains view wealth, festivals, and ritual practices, or provide a brief, quotable explanation from Jain scriptures.
