In Jainism, there is no formal ban on marrying someone from a non-Jain background (such as a Saraswat Brahmin girl). The tradition focuses on values, mutual respect, and support for a spiritual and ethical life, rather than on caste or religious labels alone.

What to consider:

• Family and community: Some families may have expectations about rituals, upbringing, or how children are raised. Open, respectful discussion can help.
• Spiritual path: If you or your partner are interested in Jain practices (diet, festivals, periodic vows, temple worship), discuss how you’ll honor that in daily life and in children’s upbringing.
• Practical matters: How you handle rituals, naming, marriage vows, and potentially temple participation can vary by local tradition (Digambar vs. Shwetambar) and by community norms.

If you want, I can share more specific guidance from Jain texts about lay vows and household life, or help you think through conversations with family and a local Jain sangh.
