Jainism teaches that “aacharna” (conduct or practice) should be performed with awareness and discipline. "Trikal" means three times a day—morning, afternoon, and evening. Many Jain rituals and practices, such as pratikraman, samayik, or reciting certain sutras, are recommended to be performed trikal (thrice daily) for spiritual purification and self-discipline.

If you wish to establish a trikal acharna (spiritual practice or discipline), here are some commonly observed practices among Jains:

1. Pratikraman:

• Performed trikal by many devout Jains:

• Involves repentance, reflection, and forgiveness.

2. Samayik:

• A vow to remain in a state of equanimity for at least 48 minutes.
• Can be done trikal as a way to center the mind and detach from passions.

3. Recitation of Sutras or Mantras:

• Namokar Mantra or other Jain prayers can be recited three times daily.

4. Daily Reflection and Vows:

• Morning: Take vows (vrats) and resolve to practice right conduct.
• Afternoon: Reflect on actions and correct any mistakes.
• Evening: Repent for any wrongdoings and seek forgiveness.

How to start trikal acharna:

1. Set aside a fixed time and place for your practice, three times a day.
2. Begin with Namokar Mantra and internal reflection.
3. Perform samayik or pratikraman as per your capability and guidance from Jain texts or a guru.
4. End each session with prayers for forgiveness (Kshamapana) and resolve to follow ahimsa, satya, and other Jain values.

It is beneficial to consult a Jain monk, nun, or knowledgeable layperson (shrāvaka/shrāvikā) for personalized guidance and correct procedure according to your Jain sect (Shvetambar, Digambar, etc.).
