century BCE, the Aryas had been in India perhaps a thousand
years and their cultural influence extended down the Gangesvalley as far as Pataliputra (modern Patna). The coming of the
Aryas into India did not bring political unity to northern India,
but it did bring a certain ideology that constitutes one of the prin-
cipal components of Indian culture. This Aryan vision of society
was principally developed and articulated by a hereditary groupwithin Aryan society known as briihmafJas or, in the Anglo-Indian
spelling, brahmins. The original literature of the brahrnins is knownas the Vedas, the oldest portions of which, found in the l_?.g Veda,
date from about rsoo BCE. By the time of the Buddha, Vedic
literature probably already comprised several different classes:the four collections (saf!lhitii) of verses attributed to the ancient
seers (r#), the ritual manuals (also known as briihmaiJas) giving
instruction in the carrying out of the elaborate Vedic sacrificialritual, and 'the forest books' (iiraiJyaka) explaining the esoteric
meaning of this sacrificial ritual. The final class of Vedic liter-
ature, the Upani~ads, containing further esoteric explanations
of the sacrificial ritual, was still in the process of formation.Two aspects of the brahmanical vision are of particular im-
portance, namely an understanding of society as reflecting a
hierarchy of ritual 'purity', and a complex system of ritual and
sacrifice. From the brahmanical perspective society comprises twogroups: the Aryas and the non-Aryas. The former consists of the
three hereditary classes (variJa) in descending order of purity:
briihmaiJaS (whose prerogative and duty it is to teach and main-tain the Vedic tradition), k~atriyas or rulers (whose prerogat-
ive and duty is to maintain order and where necessary inflictappropriate punishment), and the vaisyas (whose prerogative and
duty is to generate wealth through farming and trade). These threeclasses are termed 'twice born' (dvija) by virtue of the fact that
traditionally male members undergo an initiation ( upanayana)
into a period of study of the Vedic tradition under the super-
vision of a brahmin teacher; at the end of this period of study it
is their duty to maintain the household sacrificial fires and, with
the help ofbrahmins, carry out various sacrificial rituals in accord-
ance with the prescriptions of Vedic tradition. The non-Aryas
