Answer

Both are correct, but they are used in slightly different Jain traditions and languages.

• Micchami Dukkadam is the traditional Prakrit expression commonly used after Pratikraman, especially during Paryushan and Samvatsari.
• Khammat Khamna is a forgiveness expression commonly used in Jain communities, especially in Gujarati/Rajasthani cultural usage.

Explanation

Micchami Dukkadam means:
“May the wrong I have done become ineffective,” or “May my faults be forgiven.”

It is a deeply traditional Jain phrase used to ask forgiveness for any harm caused through:

• thoughts,
• words,
• actions,
• knowingly or unknowingly.

Khammat Khamna also expresses a request for forgiveness. It means something like:

“I ask for forgiveness,” or “Please forgive me.”

Spiritual Understanding

In Jain Dharma, the main feeling is more important than the exact phrase. The true purpose is:

• to remove ego,
• to seek forgiveness sincerely,
• to forgive others,
• to reduce anger, pride, deceit, and greed,
• to purify the soul.

Takeaway

Micchami Dukkadam is the more scripturally traditional phrase, especially after Pratikraman. Khammat Khamna is also correct as a respectful forgiveness greeting.

The most important thing is the inner feeling of sincere forgiveness and humility.
