犢子部の成立と名称について -- 舎利壷に刻まれている諸聖者あるいは伝道師名に基づく=The Origin and Name of Vātsīputrīyā: Based on List of Name of Buddhist missionaries and Theras appeared on the reliquaries
About the origin and name of Vātsīputrīyā, we used the term Vātsīputrīyāas a keyword for analysis through three kinds of evidence; Canons on both, Northern and Southern Tradition, context appeared on the reliquaries, and some associated research. We have been convinced that, from Kathāvatthu, during the time of King Aśoka, the Buddhist order was silently disunited because of the difference in the interpretations of the Buddha's teaching though the community was still called Thervada. The difference originally emerged among leaders(Theras) who influenced each region of India in which afterward the Buddhis order was divided into sects. We have made two assumptions here; first, the name of each sect might be named after the name of its leader, second the name of leaders might relate to the names appeared on the reliquaries and the name of Buddhist missionaries. Based on these two assumptions, the followers show pairs of the Buddhist missionaries or Theras appeared on the reliquaries and the corresponding sect names; Kāsapagota and Kassapika, Dhammarakkhita and Dhammaguttika, Mahādeva and andhaka, Madhyāntika and Kaśmīr Sarvāstivadin, finally Vāchiputa (Vātsīputra) and Vātsīputriyā. These evidences support our assumption and suggest that the sect name called Vātsīputriyā might be derived from the name of its leader, Vātsīputra. In addition, in the sect called Sammatīya(sub-sect of Vātsīputriyā), it was written that a monk called Vātsīputra was the one who revised the Buddha's teaching resulting in a new sect.
