Michhami Dukkadam (also spelled Micchami Dukkadam) is a Jain greeting/utterance used especially during Paryushan and after gatherings to seek forgiveness.

• Meaning: “May my misdeeds be forgiven.” It is a request for forgiveness from others for any harm caused by body, speech, or mind, and it also conveys forgiveness from the speaker to others.
• What it expresses: humility and a commitment to improve one’s conduct. It is offered to all living beings—people, animals, and the environment—reflecting the Jain emphasis on non-harm and self-purification.
• Tradition: Said at the end of a gathering or at the close of the year/holy days. There is no essential difference in meaning between Digambar and Shwetambar traditions; both use it as a sincere request for forgiveness.
• Simple usage: If you think you may have harmed someone, you can say Michhami Dukkadam to inquire forgiveness; you may also respond with forgiveness to others who say it to you.
