Michhāmi Dukkaddam (also written Michhāmi Dukkadam) is a Jain tradition used to seek and grant forgiveness at the end of Paryushan or Das Lakshan Parva. Here is the core text and meaning you asked for.

Original text (transliteration and common form)

• Khammemi Savve Jive, Savve Jiva Khammantu Me, Metti Me Savve Bhuiye, Veram Maajhham N Kenaī
• Devanagari (common form in practice): खामेमि सव्व जीवे, सव्वे जीवा खमंतु मे, मित्ति मे सव्व-भूएसु, वेरं मज्झ न केणए।

Meaning (arth) in Jain tradition

• I forgive all living beings with a true, whole-hearted intent.
• I beg forgiveness from all living beings for any harm I may have caused, knowingly or unknowingly, by body, speech, or mind.
• I have no ill will toward anyone, and I wish goodwill to all.

Important notes about practice and tradition

• Essence: It is an expression of ahimsa (nonviolence), humility, and reconciliation. The aim is to purify the mind by granting and seeking forgiveness from all beings.
• Timing: Commonly recited on Samvatsari (the last day of Paryushan) by Svetambar Jains, and on Kshamavani in Digambar practice. Both traditions use a form of this confession/forgiveness, though the naming and exact ritual timing may differ.
• Digambar vs. Śvetāmbara: The exact label for the forgiveness day differs (Samvatsari for Śvetāmbara; Kshamavani for Digambara), but the spirit and the core text of seeking/ grant forgiveness remain aligned in both traditions.
