In Jainism, breaking a fast (known as "Parna") is an important and sacred act, often performed with gratitude and mindfulness. Before taking the first morsel of food or water after a fast, Jains recite specific prayers or mantras to express reverence and seek forgiveness for any mistakes made during the fast.

A commonly recited mantra at the time of breaking the fast is the Navkar Mantra (Namokar Mantra), which is the most fundamental and revered prayer in Jainism. Additionally, many Jains recite the following phrase:

"Micchāmi Dukkaḍaṃ" This phrase means "May all the evil that has been done be fruitless," and is often said to seek forgiveness.

For longer or more significant fasts (such as during Paryushan), Jains may also recite:

"Icchāmi Khamāsaman" This means "I seek forgiveness" and is recited to ask for pardon for any faults committed during the fast.

The process typically involves:

1. Reciting the Navkar Mantra.
2. Saying "Micchāmi Dukkaḍaṃ" or "Icchāmi Khamāsaman".
3. Expressing gratitude and remembering the Tirthankaras and spiritual teachers.

Note: The exact practice may vary depending on sect (Shwetambar or Digambar) and family traditions, but the Navkar Mantra is universally accepted for auspicious occasions, including breaking a fast.

Navkar Mantra: ``` णमो अरिहंताणं। णमो सिद्धाणं। णमो आयरियाणं। णमो उवज्झायाणं। णमो लोए सव्व साहूणं॥ ```

Translation: "I bow to the Arihants (enlightened beings), I bow to the Siddhas (liberated souls), I bow to the Acharyas (spiritual leaders), I bow to the Upadhyayas (spiritual teachers), I bow to all the Sadhus (saints) in the world."

In summary: The Navkar Mantra is most commonly used when breaking a fast, sometimes followed by "Micchāmi Dukkaḍaṃ" or "Icchāmi Khamāsaman" as a prayer for forgiveness.
