In Jain Dharma, kundali matching is a cultural practice, not a core religious rule.

For an arranged marriage, the more important Jain values are:

• similar faith and practices
• good conduct and character
• mutual respect
• family harmony
• shared commitment to Ahimsa, Satya, and Aparigraha

So, if a family wishes to match kundali, it can be done as a tradition, but from a Jain spiritual point of view, it is not mandatory. The real foundation of a good marriage in Jain life is compatibility in values, conduct, and devotion to Dharma.

If you want, I can also explain this from the Jain social and ethical perspective.
