In Jainism (including Śvetāmbara Terāpanth), this is mainly a social / medical question, not a scriptural one.

1. From Jain dharma side (shāstras & principles)

- Jain scriptures do not list detailed blood‑relation rules like “second cousin marriage allowed / not allowed”. - Basic principles are: - Avoid himsā (harm) – including physical, mental, social disturbance. - Follow local nyāy / law of the land. - Keep family and social harmony. - So, there is no direct Jain‑shastric ban specifically on “second cousin marriage”. Such details are decided by community customs and modern medical guidance.

1. From Terāpanth samāj practice

- Terāpanth (Acharya Bhikshu–Acharya Mahāśramaṇ ji’s tradition) generally follows strict endogamy and gotra/close‑relation restrictions, similar to other Jain communities. - As a community norm, most Terāpanthi families avoid marriages in close blood relations (first cousin, sometimes even second cousin), because: - Socially it is not liked in many Jain communities. - Medically, close‑relation marriages can increase genetic risk. - Exact rule (whether your particular “second cousin” relation is acceptable) is usually decided by: - Family elders - Local Terāpanth sabhā / samaj - Sometimes by consulting doctors for genetic risk

1. What you should practically do

- Confirm the exact relation (sometimes people call many relations “cousin”). - Talk to: - Your parents / elders - Local Terāpanth samaj / Adhyatma Sādhanā Kendra / sabhā - Also check: - Legal rule in your country/state about relatives’ marriage - Medical/genetic advice if the blood relation is close

From pure Jain dharma side: focus is on ahimsā, nyāy, and family harmony; it does not command you to marry a cousin nor to specifically label “second cousin marriage” as a sin. From Terāpanth community side: in practice, close‑relation marriages are usually discouraged, so you must take local guidance.
