Две палийские надписи в Сарнатхе: 2-3 века нашей эры и 3-4 века нашей эры. От Кашьяпии к Тхераваде.

Две палийские надписи в Сарнатхе (2-3 века нашей эры и 3-4 века нашей эры) подкрепляют гипотезу о том, что первая редакция Палийского канона была записана в Индии

а на Ланку, вместе с языком пали, принесена школой Кашьяпия. Так же, подкрепляет представление о том, что у всех школ Стхавира-никаи (Абхаягири, Джетавании, Махавихары) были общие Сутты и Виная (наследие древнеиндийской Кашьяпии).

Кроме как не из Кашьяпии, палийскому буддизму больше неоткуда взяться, потому что Вибхаджьявада - не школа, а вот Кашьяпия - совершенно конкретная школа, связанная с Ланкой.

Тамрашатия - которая дочерняя школа Сарвастивады?

The Pali Samyutta-nikiaya (abbreviated SN) and the Chinese Samyuktiagama (abbreviated SA) are, roughly speaking, two different versions of the same collection of suttas/sutras or discourses. SN is the version preserved in Pali language within the Tamrasatiya school (the selfstyled Theravada), which was formerly active in western India (the region of Ujjeni) , and which still flourishes in Sri Lanka and southeast Asia.

A council, called the "Third Council" in the tradition of Pali Buddhism, was held in 251 BC at Pataliputra (modern Patna) under the patronage of the emperor ASoka (reigned c. 268-232 BC), in order to establish the identity of the Vibhajyavada. Subsequent subdivision within each of these two sub-branches led to the numerous Sthavira schools. One of the Vibhajyavada schools became the Tamrasatiya, which early established itself on Sri Lanka. Although it calls itself Theravada (Skt. Sthaviravada) "the Teaching of the Elders" or Vibhajjavada (Skt. Vibhajyavada) "the Distinctionist Teaching", the Tamrasatiya is actually a sub-school of the Vibhajyavada, which in its turn is a derivative of the Sthavira or "Elder" branch. It is here called Pali Buddhism. The Sarvastivada is also a derivative of the Sthavira. Thus, both Pali Buddhism and Sarvastivada belong to the Sthavira branch of Sectarian Buddhism; the other main branch was the Mahasanghika.

   12. Also called Tamraparnya or Tambapa[m]naka, referring to the Buddhist sect or monks of Tamraparni (P. Tambapanni = Lanka, Sihala; i.e. today's Sri Lanka). Cf. LAMOTTE, pp. 120, 301-302, 526, 536, 547, 786; Yin Shun, History, p. 45.

Each school appears to have had its Tripitaka or "Three-baskets", comprising Sutra, Vinaya, and Abhidharma. Most of these texts were early converted from various Prakrits (Middle Indo-Aryan dialects) into "Buddhist Sanskrit". However, the Tamrasatiya school's version of the Tripitaka has been preserved in a Prakrit, the so-called Pali (literally, "text"), which is based on a dialect from the region of Ujjeni (Ujjayani), capital of Avanti, in western India. Only this Pali version has been preserved intact. Most of the other Tripitakas were subsequently lost, but major portions are preserved in Chinese translations.

... Yin Shun points out that this discourse, which has no SA counterpart, is affirming the theory of "the existence of present time", a teaching of the Tamrasatiya tradition (Pali Buddhism).
