The reason for this lies as much as anything in the nature of the Buddhistic system which is expressly declared to be "for the wise, not for the foolish." It was not a system based as such on love or on any democratic sentiment. It was a philosophical exposition of the causal nexus of birth and freedom from re-birth. The common man, untrained in logic, might adopt the teaching, but he could not understand it. The "Congregation of the son of the Ç[=a]kyas"--such was the earliest name for the Buddhistic brotherhood--were required only to renounce their family, put on the yellow robe, assume the tonsure and other outward signs, and be chaste and high-minded. But the teachers were instructed in the subtleties of the 'Path,' and it needed no little training to follow the leader's thought to its logical conclusion. Of Buddha's life, besides the circumstances already narrated little is known. Of his disciples the best beloved was [=A]nanda, his own cousin, whose brother was the Judas of Buddhism. The latter, Devadatta by name, conspired to kill Buddha in order that he himself might get the post of honor. But hell opened and swallowed him up. He appears to have had convictions of Jain tendency, for before his intrigue he preached against Buddha, and formulated reactionary propositions which inculcated a stricter asceticism than that taught by the Master.[20] It has been denied that the early church contained lay members as well as monks, but Oldenberg appears to have set the matter right (p. 165) in showing that the laity, from the beginning, were a recognized part of the general church. The monk (_bhikshu, bhikku_) was formally enrolled as a disciple, wore the gown and tonsure, etc. The lay brother, 'reverer' (_up[=a]saka_) was one that assented to the doctrine and treated the monks kindly. There were, at first, only men in the congregation, for Buddhism took a view as unfavorable to woman as did Jainism. But at his foster-mother's request Buddha finally admitted nuns as well as monks into his fold. When [=A]nanda asks how a monk should act in presence of a woman Buddha says 'avoid to look at her'; but if it be necessary to look, 'do not speak to her'; but if it be necessary to speak, 'then keep wide awake, [=A]nanda.'[21] Buddha died in the fifth century. Rhys Davids, who puts the date later than most scholars, gives, as the time of the great Nirv[=a]na, the second decade from the end of the fourth century. On the other hand, Bühler and Müller reckon the year as 477, while Oldenberg says 'about 480.'[22] From Buddha's own words, as reported by tradition, he was eighty years old at the time of his death, and if one allots him thirty-six years as his age when he became independent of masters, his active life would be one of forty-four years. It was probably less than this, however, for some years must be added to the first seven of ascetic practices before he took the field as a preacher.
