There is no standard Jain term like “vitamin of pratikaman.” In Jain texts, the core practice of Pratikraman (pratikaman) is built from the Six Avashyaks (essential rituals): Samayik, Chauvisantho, Vandana, Pratikraman (alochana), Kayotsarga, and Pratyakhyan. These are the spiritual “nourishments” that make pratikaman effective, not a single “vitamin.” Different Jain communities (Digambara and Śvētāmbara) may have slight sequence or wording differences, but the fundamental aim remains the same: inner calm, confession, forgiveness, and renewed vows to avoid faults.
