In Jainism, “gotra” generally means family lineage or clan name, used mainly in social and matrimonial matters – not in core Jain spiritual philosophy.

Simple points:

1. Not a main religious concept

- Jain Agams and main scriptures do not make gotra a spiritual rule. - Your soul’s progress does not depend on gotra; it depends on samyak darshan, gyan, charitra (right faith, knowledge, conduct).

1. Social / family use

- Among many Śvetāmbara (Oswal, Porwal, etc.) families, there is a tradition of 84 gotras (chourasi gotra). - These are clan names used mainly to avoid marriage within the same gotra and to remember ancestry. - The list and names can differ from one community to another.

1. Digambar vs. Śvetāmbara

- Both treat gotra as a social label only. - Especially in many Digambar families, gotra is either not used at all or used only loosely; people go more by surname, place, or community name. - For monks/nuns of both traditions, gotra is irrelevant; they leave family identity altogether.

1. Difference from “varna”

- Varna = old social category (Brahmin, Kshatriya etc., from Hindu system). - Gotra = lineage / clan name. - Jain Dharma does not give spiritual importance to either varna or gotra; only karma and conduct matter.

In short: Gotra in Jainism = family/clan identification used by some Jain communities, mainly for social and marriage purposes, not a spiritual or scriptural requirement.
