(Second, regarding those of dull faculties who repent relying on phenomenal practice: if relying on the Mahāyāna, texts such as the Buddha Names and the Vaipulya fully set out ritual procedures to repent in accordance with the Dharma, which strictly requires signs to manifest and verifying one's mind according to the teachings. If relying on the Vinaya tradition, one must recognize the classes and characteristics of the offenses, and formally document and confess them as they occur. If there is doubt and one cannot recognize them, it is not permissible to apply the formal procedure, except in the case of those who do not study, where the fundamental offense is determined according to what was committed; this only eradicates the offense of violating the precepts. Therefore, the Mahāprajñāpāramitopadeśa says: "Even if an offense in the Vinaya is subtle, through repentance it becomes pure; but if one violates the precepts of the ten good actions, although one repents, the offenses leading to the three evil destinies are not eliminated, just as when a bhikṣu violates natural precepts, and the like.")
