According to Jainism, the fundamental principles guiding life are non-violence (ahimsa), truth (satya), non-possessiveness (aparigraha), and equality of all souls. Jain philosophy does not support discrimination based on caste, birth, or social status. All souls are considered equal, and spiritual progress is based on individual conduct and efforts rather than one's birth or caste.

Marriage in Jainism is viewed as a social institution, and Jain scriptures do not lay down explicit rules about caste in marriage. Especially in contemporary Jainism, many acharyas and learned monks emphasize the irrelevance of caste and stress on good character and mutual understanding between the couple.

However, Digambar Jain monks (Maharaj ji) strictly observe celibacy and complete detachment from worldly affairs. They do not participate in or approve social matters such as marriages, nor do they give personal endorsements about individual matches, as their life is dedicated to spiritual upliftment and renunciation. They may, in their discourses, speak about the Jain view of equality and non-discrimination, but they do not give personal approvals for marriages.

If her father seeks a Maharaj ji's opinion, you may attend discourses of respected Digambar Jain monks, where you might hear general encouragement towards equality and non-discrimination. Still, monks will not provide individual permissions or endorsements for marriages, as this is outside their monastic conduct.

Suggestions from a Jain perspective:

• Emphasize the Jain values of equality and non-discrimination in discussions with her family.
• Seek guidance from lay Jain scholars (pandits or upadhyays) or respected elders in the Jain community, who may help explain Jain philosophy to her parents.
• Remember, Jainism encourages peaceful and non-violent resolution of conflicts and upholding truth and compassion in all actions.

In summary, while Jainism does not support caste discrimination and upholds the equality of all souls, Digambar Maharaj jis do not give approvals for marriages. You may seek support from learned laypersons or community elders for guidance.
