Introduction about the faults of vinaya wich not included in the pātimokkha.
There are no thullaccaya among the 227 rules of the pātimokkha. Therefore these were not taught separately. As with many other aspects, the thullaccayas were established by the Buddha as transgressions whose gravity is just lesser than that of the pārājikas and the saṃghādisesas.
Essentially, the thullaccayas are preliminary offences that a bhikkhu may commit before a pārājika or a saṃghādisesa.
According to the pārājika 1, the bhikkhu who has a sexual relation by means of the mouth, the anus or the genitals of a corpse commits a thullaccaya. Similarly, by introducing his sex organ in one of the following: the sex organ of a female living being where this is narrower than that of a cat or a chicken; in the eye orifice, the nostrils or the ear of a human being; in the corpse of a being through an opening made with a knife or into a fold; in the nose of the corpse from an elephant, horse, buffalo, cow, etc. He commits also a thullaccaya by superficially touching the genitals of a female living being with his without penetration; by giving oral caresses to a woman's sex organ with lustful desire; by having his sex caressed by the mouth or tongue of a woman without the sex entering her mouth.
Remarks: Some thullaccayas are inseparable from other offences, such as the saṃghādisesas.
There are also thullaccaya that are not linked to the pārājika or to the saṃghādisesa. If a bhikkhu eats human flesh, wears the robe of an heretic sect in wood bark, a robe made out of owl feathers or from a cloth made with human hairs, or if he cuts his sexual organ, he commits a thullaccaya.
Any transgression committed by a bhikkhu that is the object of a sekhiya but not the object of a pātimokkha rule is a dukkaṭa or a dubbhāsita. A dukkaṭa is a minor offence caused by an unskilful action, whereas a dubbhāsita is a minor offence due to unskilful speech.
These offences are very numerous. There is no list detailing them in precise order. The passages that specify the dukkaṭas and dubbhāsitas are dispersed throughout the vinaya texts. Notably, many of them are explained within the pātimokkha itself.
A bhikkhu who eats at the same table as a lay person (or a sāmaṇera), commits a dukkaṭa.
A bhikkhu who places his bowl on a wall or on the ground (without a support), commits a dukkaṭa.
A bhikkhu who is transported by an animal or on a bicycle, commits a dukkaṭa.
A bhikkhu wearing stained garments, commits a dukkaṭa.
A bhikkhu who uses the toilet without previously lifting his robe, commits a dukkaṭa.
A bhikkhu who engages in or encourages a futile conversation, commits a dubbhāsita.
A bhikkhu who utters a vulgar word commits a dubbhāsita.
