Before starting Ekashana (one meal a day) during Paryushan, Jain munis (monks) or knowledgeable laypersons often recite or encourage devotees to recite specific prayers (slokas) and take certain vows (niyams) to set the right intention and purify the act. The process and the prayers may vary slightly among different sects (Shwetambar and Digambar), but generally, the following are recited:

Common Slokas and Rituals Before Ekashana:

1. Pratikraman Sutras

Before Ekashana, many Jains perform Pratikraman, which includes reciting sutras like:

• Namokar Mantra (Navkar Mantra): The most fundamental prayer in Jainism.
• Khamemi Savve Jiva: Asking forgiveness from all living beings.

2. Pachkhan (Vow)

A formal vow called Pachkhan is taken, which is a declaration of the self-imposed restriction. The Pachkhan for Ekashana may go as follows (example in English translation):

"I take the vow that today I will do Ekashana, that is, I will eat only once in a day, at a fixed time, without any attachment, and with pure intentions, following all the rules prescribed in Jain scriptures."

The exact Pachkhan in Prakrit or Gujarati (for Shwetambar sect) is: ``` Aaj thi hu(n) ek samay niyam rakhu(n) chu(n). Ek samay ekasane karis, biji vaar bhojan na karu(n). ```

3. Bhaktamar Stotra or Other Stotras

Some devotees may recite stotras like Bhaktamar Stotra or Uvasaggaharam Stotra for spiritual strength and focus.

4. Alochana (Confession)

Short confession may be performed, seeking forgiveness for any mistakes in observance.

Typical Sequence:

1. Namokar Mantra
2. Alochana (Confession/Repentance)
3. Pachkhan (Niyam) for Ekashana
4. Optional: Recitation of other stotras or prayers

Example Pachkhan (in English):

"Oh Arihant Bhagwan! Today, I take the vow to perform Ekashana—one meal only, at one sitting, without attachment, as per Jain rules. I will not eat or drink anything else until tomorrow's sunrise."

Summary: Before starting Ekashana during Paryushan, Jains recite the Namokar Mantra, perform Alochana (repentance), and take the Pachkhan (vow) for Ekashana, sometimes accompanied by other stotras or prayers. This is done to purify the intent and ensure the austerity is performed in accordance with Jain principles.
