After the Sa@mhitâs there grew up the theological treatises called the Brâhma@nas, which were of a distinctly different literary type. They are written in prose, and explain the sacred significance of the different rituals to those who are not already familiar with them. "They reflect," says Professor Macdonell, "the spirit of an age in which all intellectual activity is concentrated on the sacrifice, describing its ceremonies, discussing its value, speculating on its origin and significance." These works are full of dogmatic assertions, fanciful symbolism and speculations of an unbounded imagination in the field of sacrificial details. The sacrificial ceremonials were probably never so elaborate at the time when the early hymns were composed. But when the collections of hymns were being handed down from generation to generation the ceremonials became more and more complicated. Thus there came about the necessity of the distribution of the different sacrificial functions among several distinct classes of priests. We may assume that this was a period when the caste system was becoming established, and when the only thing which could engage wise and religious minds was sacrifice and its elaborate rituals. Free speculative thinking was thus subordinated to the service of the sacrifice, and the result was the production of the most fanciful sacramental and symbolic ____________________________________________________________________ [Footnote 1: A.A.

Max Muller (_S.B.E._, I.p. lxvi) says that Brâhma@na meant "originally the sayings of Brahmans, whether in the general sense of priests, or in the more special sense of Brahman-priests." Eggeling (S.B.E. XII. Introd. p. xxii) says that the Brhâma@nas were so called "probably either because they were intended for the instruction and guidance of priests (brahman) generally; or because they were, for the most part, the authoritative utterances of such as were thoroughly versed in Vedic and sacrificial lore and competent to act as Brahmans or superintending priests." But in view of the fact that the Brâhma@nas were also supposed to be as much revealed as the Vedas, the present writer thinks that Weber's view is the correct one.] 14 system, unparalleled anywhere but among the Gnostics. It is now generally believed that the close of the Brâhma@na period was not later than 500 B.C. The Âra@nyakas.
