Тхеравада - новодел?

.На Ланке, в Таиланде и Бирме есть понятие "ереси" и, плюс ко всему, там "буддийскую магию" называет "тантрой" - я правильно понял?

Ahistorical Inventions: Ariya Buddhism and Other Chimera
Modern scholarship has compounded the confusion by coining new
terms for the Buddhism of Southeast Asia. These late twentieth cen-
tury neologisms include “Lopburi Hīnayāna” and “Ariya Buddhism,”
“Tantric Theravāda,” “Siamvaṃsa school,” and “Sukhavatī school.”
This is not the place to address the problem of these curious inven-
tions, and I will briefly take up only one example, Tantric Theravāda.
Neither Thai nor Khmer Buddhism, as seen above, represents itself as
“Theravadin”—let alone “Tantric.” In India itself the word “tantra” is
contested—there is no agreement as to what the long-lived, diverse,
multicultural, multireligious term “tantra” means. It is noted in the
Encyclopedia of Buddhism that “Tantra in Western nomenclature has
achieved forms of signification independent from its Sanskritic use and
has become a somewhat promiscuous category applied to various ritu-
als not easily classified.” The word “tantra” is not used in Southeast
Asian Buddhism to describe either texts or practices (and the adjective
tāntrika is equally unknown). There is no problem in drawing paral-
lels (if there are any): that is our job. But when we place Khmer or
Southeast Asian practice within a category alien to it, then, inevitably,
everything else about tantra is associated with it, and confusion reigns.

Говорят что было примерно так

Sthaviravāda -> Vibhajjavāda -> Theravāda

2. Там - имена собственные. "Тантрой" (чаще - "тантрическими")  называют европейские исследователи.

Дхаммакая в Таиланде - подходит.

С придумкой еровпейцами термина "тхеравада", на основании древней истории раскола на махасангхиков и стхавир, забавно то, что на тот момент не было известно, что все современные школы, включая даже амидаистов, это потомки исключительно тех стхавир, а не махасангхиков. То есть, термин создан из-за ошибки.

Стхавиравада относилась в принципе к вибхаджаваде.

The Vibhajyavādins are not recorded uniformly by early Buddhist traditions as being a distinct sect, nor being associated with any one period of time.

Mahāsāṃghikas saw the Vibhajyavādins as being offshoots from the root schism in Buddhism, which according to them produced three sects: the Sthaviras, the Mahāsāṃghikas, and the Vibhajyavādins.

The Sarvāstivādin Abhidharma Mahāvibhāṣa Śāstra describes the Vibhajyavādins as being the type of heretics who "make objections, who uphold harmful doctrines and attack those who follow the authentic Dharma".

Some scholars believe that there was no separate "Vibhajyavāda" sect, but that the term vibhajyavāda was sometimes affixed to the name of a school to indicate that it differed from the main school on some doctrines. In this sense, they would be vibhajyavādins of that particular school. This is also found in the Mahāsāṃghika branch with the Prajñaptivāda school, whose members preferred to be called Bahuśrutiya-Vibhajyavādins. It has been suggested that the Theravādins of Sri Lanka may have been Sthavira-Vibhajyavādins, differing somewhat from the main Sthavira school in their doctrinal interpretations.

Ересь, то есть. Это видимо филологически - вибхаджа-(вада), как "отличающиеся (от основной школы)", а не как "различающие (дхармы)"
