The phenomenon of the schism represented by the two divisions of the Yazur Veda, the "White" and the "Black," is plausibly accounted for as the outcome of the tendencies of a new and an old school, who selected from their Brahmanas, or treatises of ritual and theology, the portions which respectively suited them. The implied critical movement would tend to affect official thought in general. This schism is held by Weber to have arisen only in the period of ferment set up by Buddhism; but other disputes seem to have taken place in abundance in the Brahmanical schools before that time. (Cp. Tiele, Outlines, p. 123; Weber, Hist. Ind. Lit., pp. 10, 27, 232; Max Müller, Anthropol. Relig., 1892, pp. 36-37; and Rhys Davids, Buddhism, p. 34.) Again, the ascetic and penance-bearing hermits, who were encouraged by the veneration paid them to exalt themselves above all save the highest Gods, would by their utterances of necessity affect the course of doctrine. Compare the same tendency as seen in Buddhism and Jainism (Tiele, pp. 135, 140). But in the later form of the Vedânta, "the end of the Veda," a monistic and pantheistic teaching holds its ground in our own day, after all the ups and downs of Brahmanism, alongside of the aboriginal cults which Brahmanism adopted in its battle with Buddhism; alongside, too, of the worship of the Veda itself as an eternal and miraculous document. "The leading tenets [of the Vedânta] are known to some extent in every village." [162] Yet the Vedântists, again, treat the Upanishads in turn as a miraculous and inspired system, [163] and repeat in their case the process of the Vedas: so sure is the law of fixation in religious thought, while the habit of worship subsists. The highest activity of rationalistic speculation within the Brahmanic fold is seen to have followed intelligibly on the most powerful reaction against the Brahmans' authority. This took place when their sphere had been extended from the region of the Punjaub, of which alone the Rig-Veda shows knowledge, to the great kingdoms of Southern India, pointed to in the Sutras, [164] or short digests of ritual and law designed for general official use. In the new environment "there was a well-marked lay-feeling, a widespread antagonism to the priests, a real sense of humour, a strong fund of common sense. Above all there was the most complete and unquestioned freedom of thought and expression in religious matters that the world had yet witnessed." [165]
