For the Jain “Shah” surname, there is no single, fixed Kuldevi for all Shah Jains.

In Jain tradition:

1. “Shah” is a broad surname

- Used by many Jain families, mainly Gujarati/Marwari vaniya and merchant communities. - Different Shah families can belong to different gotras, villages, and even different sects (Śvetāmbara / Digambar).

1. Kuldevi is family‑specific, not surname‑specific

- Kuldevi/Kuldev is decided by: - your gotra / lineage, - your ancestral town or village, - and your family tradition. - So one Shah family may follow Padmavati, another Ambika/Kushmandini, another Chakreshwari, or in some Oswal-type lineages even a regional devi like Suswani Mataji, etc. - Jain dharma’s main focus is always Tirthankars; such devis are respected as protective attendants (śāsan-devīs), not as supreme gods.

1. How to find your Shah family’s Kuldevi

- Ask grandparents/elders: They usually know which Kuldevi’s name is taken at weddings and major rituals. - Check old vahi / family bahi‑khata (traditional account books) – the Kuldevi name is often written there. - Ask at your ancestral derasar: local people or inscriptions sometimes mention which Kuldevi a community (e.g., Shahs of that town) follows. - Note whether your family is Śvetāmbara or Digambar, because practices and common devis may differ.

1. Jain dharmic view

- Whether or not a family has a Kuldevi, spiritual progress in Jainism depends on: - following ahimsa, - anuvrat / vows, - samyak darshan‑jnan‑charitra (right faith, knowledge, conduct), - not on which Kuldevi is followed.
