This threefold penance, practised with perfect faith, by men who do not wish for the fruit, and who are possessed of devotion, is called good. The penance which is done for respect, honour, and reverence, and with ostentatiousness, and which is uncertain and transient, is here called passionate. And that penance is described as dark, which is performed under a misguided conviction, with pain to oneself, or for the destruction of another.
