Khamat khamna meaning

Khamat khamna means a personal apology. It literally conveys “Please forgive me” and is a direct request for forgiveness from a specific person (for a particular fault or harm), rather than a universal request.

• It is distinct from Michchami Dukkadam, which is a universal forgiveness vow addressed to all beings.
• In both Digambar and Śvetāmbara traditions, the spirit is the same: humility, remorse for hurting others, and a wish to purify karma.
