In Jainism, asking the guru (preceptor) for prayāścitta is a way to acknowledge a fault and start the process of purification. The guru guides you on how to atone properly, based on the gravity of the mistake and your capacity to endure the penance.

What typically happens:

• Alochana (confession): You openly confess the mistake to your senior, with a sincere heart.
• Pratikraman (repentance): You reflect, vow not to repeat the fault, and renew your commitment to right conduct.
• Then nature of penance or remedy: Depending on the fault, you may undertake internal disciplines (like more careful self-control) or specific penances (fasting, restraint, etc.), and in some cases adjust status-related aspects (monastic seniority, etc.), as advised by the guru.
• The aim is to remove the karmic taint and strengthen future conduct.

Both Digambar and Śvetāmbara traditions acknowledge prayāścitta, with confessional and penitential practices at their core. The exact forms and emphasis can vary by tradition and situation, but the essential spirit—honest confession, remorse, and a renewed vow to avoid the fault—remains the same.
