- Marriage is not allowed at all.
- They must be completely celibate.
For laypeople:
- Marriage is permitted and normal, but:
- Should be simple, without show-off and violence (ahimsa-based functions)
- Partners should support each other in following Jain principles: non-violence, truth, vegetarianism, aparigraha, etc.
- The goal is not just worldly pleasure, but helping each other in spiritual progress.
So:
If you choose the householder path, marriage is allowed and accepted.
If you choose the monk/nun path, marriage is completely given up.
