In Jain Dharma, spiritual worth is not decided by caste or surname. A person becomes a Jain by following the path of Ahimsa, Satya, Asteya, Brahmacharya, and Aparigraha, and by taking faith in the teachings of the Tirthankars.

So, if someone belongs to the Lodha community, they can be Jain if their family follows Jain dharma and practices Jain beliefs and vows. But caste itself does not make one Jain.

In short:

• Jain identity = faith and practice
• Caste/surname = social identity
• Both are different in Jain view

If you want, I can also explain the difference between Jain religion and caste/community identity in simple words.
