Отрывок из "Тибетского ренессанса":
Second, there were the Bendé and associated quasi monks, who were like the modern Tibetan lay religious (chos pa): part clergy, part laity, and intermittently observing some monastic traditions. They and others, like the "Arhats with hair tufts," developed peculiar attributes of dress and coiffure, some of which appear similar to forms seen among the warrior monks (dab dob).The Bendé were closely associated with the temples of the old royal dynasty that based their functioning on precedents from the dynastic period.
Далее в тексте это группа упоминается несколько раз, но без подробностей.
Вот, например, цитата из "пророчества" их порицающего (из той же книги):
But then there will be Bende who are emanations of the devils family. ... The Bende will lay siege to Nezhi (in Lhodrak), raising embankments and fortifications. With spears they will impale monks and cast discus weapons at them. Then these Bende will plunder the [monks,] temples, fighting with the chaplains over the offering vessels.
P.S. Это не нгакпа (более ранний период).
В словаре этой книги так: Clerics, sometimes having a family, sometimes monks.
