In Jainism, when breaking a fast—especially a longer or significant fast such as during Paryushan or after observing upvaas (fasting)—it is customary to recite the “Micchami Dukkadam” prayer, seeking forgiveness from all beings. However, the specific mantra or phrase used at the time of breaking the fast is:

“Abbhakkhāna” (also known as Abbhigraha mantra or Paushad Patra mantra).

The devotee recites:

"Icchāmi khāum, savva jīvāṇaṁ karaṇena, savva pāvaṁ appāṇaṁ mokkhāmi."

This translates to: "I wish to eat, and by doing so, I ask forgiveness from all living beings and I atone for any sin that may occur."

This mantra expresses the intention to consume food, while seeking forgiveness for any harm that might be caused to living beings during the act of eating.

Summary: When breaking a fast, Jains recite the Abbhakkhāna mantra or state their intention to break the fast with humility and seek forgiveness from all living beings.
