About traditions:

• The list and basic meanings of these 18 paaps are accepted in both Digambar and Shwetambar traditions.
• Words or order may differ slightly in some books, but the substance is the same: we recognise these 18 as main doors through which bad karma enters, and we ask forgiveness for them in pratikraman and other sutras.
