In Jainism, scriptures mainly give principles (ahimsa, satya, brahmacharya, aparigraha, etc.), not detailed “who exactly you can marry” blood‑relation charts.

So, about marrying your 2nd cousin (your dad and their mom are first cousins):

1. From pure Jain dharma point of view

- Jain shastras focus on: - No sexual misconduct (for householders: one spouse, faithfulness, self‑control). - Avoiding harm (physical, emotional, social). - They do not directly list “2nd cousin marriage is allowed / not allowed.” - So the religious text itself is not giving a clear yes/no on this exact relation.

1. From traditional Jain community/custom point of view

- Most Jain communities: - Avoid marriage in very close blood relations (like own first cousin, brother‑sister, etc.). - Often follow gotra / family-line distance rules and general Indian medical/common‑sense norms. - In many Jain families, even if something is not clearly “sinful” in scripture, they still discourage close‑blood marriages to: - Avoid health/genetic risks for children. - Avoid social criticism and family conflict.

1. Practical and ethical guidance (Jain viewpoint)

- Think in terms of: - Ahimsa – No harm to future children (genetic risk), no big family fights, no mental suffering. - Satya & Aparigraha – Be honest with yourself and family; don’t cling to one relationship if it will create long‑term pain for many people. - Because this is a blood relation not very far, it is safer and more in line with Jain ethics to: - Check legality and medical advice (genetic counselling). - Take guidance from knowledgeable Jain elders / local guru / samaj who know your family tree and local customs.

1. Simple conclusion

- Jain scriptures do not explicitly say “you are committing a big paap if you marry a 2nd cousin.” - But Jain values + medical and social wisdom usually go against marriages in close blood relations. - For spiritual safety, health reasons, and family harmony, it is generally better to avoid such a close‑relation marriage unless: - It is clearly legal where you live, - A good doctor/genetic counsellor says risk is minimal, and - Wise Jain elders who know your family support it.

If you share your Jain sect and community (e.g., Shwetambar–Oswal, Digambar–… etc.) with a local guru or elder, they can tell you the exact custom your samaj follows for such relations.
