Six ill-behaved monks whose conduct often causes the Buddha’s establishment of new rules: Nanda, Upananda, Punarvasu, Chanda, Aśvaka, and Udāyin.

A group of six monks who are portrayed in Vinaya texts as constantly pushing the limits of the disciplinary rules established for the monastic community.

A certain band of monks of the Buddha’s order who appear throughout the vinaya literature as examples of those who break the monastic rules. In Pāli their names are given as Assaji, Punabbasu, Panduka, Lohitaka, Mettiya, and Bhummaja. The Hundred Deeds contains one story in which they trick the nun Sthūlanandā into thinking that they can help her attain magical powers.
