Brief answer from Jain dharma perspective:

• There is no religious prohibition in Jainism against marrying someone from a different caste. Caste as a social category is not a spiritual criterion in Jain teachings.
• What matters in Jain marriage is the spiritual alignment and mutual commitment to ahimsa (non-violence), truth, renunciation of harm, and supporting each other on the path of purushartha (spiritual progress). A Jain household should aim for shared values, ethical conduct, and fidelity to dharma.
• Historically, many Jain communities practiced endogamy (within a community) for social reasons, but this is a social norm rather than a doctrinal rule. The scriptures do not declare inter-caste marriage as a sin; they emphasize the purification of the soul through right conduct, not the caste of the partner.
• Digambar and Śvetāmbara traditions both uphold Jain vows and the ideal of spiritual partnership. Differences between the sects are more about rituals, monastic codes, and philosophical emphasis than about a ban on inter-caste marriage. In practice, attitudes toward inter-caste marriage can vary by region and community, and sometimes social pressure remains in certain areas.

Key takeaway: From the core Jain view, the soul’s progress and the couple’s commitment to ahimsa and dharma matter far more than caste. If you’re facing family or community concerns, focus on shared Jain values, pious living, and open, respectful dialogue to align on matters of faith and daily conduct.
