The power and authority of a priesthood can only be maintained on the doctrine that man is 'saved' by the deeds of a ceremonial law; any general belief that morality is more acceptable to gods than ceremonies must be fatal to those occult and fictitious virtues which hedge about every pious impostor. Sacerdotal power in India depended on superstitions carefully fostered concerning the mystical properties of a stimulating juice (soma), litanies, invocations, and benedictions by priests; upon sacrifices to the gods, including their priests, austerities, penances, pilgrimages, and the like; one characteristic running through all the performances--their utter worthlessness to any being in the universe except the priest. An artificial system of this kind has to create its own materials, and evoke forces of evolution from many regions of nature. It is a process requiring much more than the wisdom of the serpent and more than its harmfulness; and there is a bit of nature's irony in the fact that when the Brahman Rishi gained supremacy, the Cobra was also worshipped as belonging to precisely the same caste and sanctity. There are traces of long and fierce struggles preceding this consummation. Even in the Vedic age--in the very dawn of religious history--Tetzel appears with his indulgences and Luther confronts him. The names they bore in ancient India were Viswámitra and Vasishtha. Both of these were among the seven powerful Rishis who made the hierarchy of India in the earliest age known to us. Both were composers of some of the chief hymns of the Vedas, and their respective hymns bear the stamp of the sacerdotal and the anti-sacerdotal parties which contended before the priestly sway had reached its complete triumph. Viswámitra was champion of the high priestly party and its political pretensions. In the Rig-Veda there are forty hymns ascribed to him and his family, nearly all of which celebrate the divine virtues of Soma-juice and the Soma-sacrifice. As the exaltation of the priestly caste in Israel was connected with a miracle, in which the Jordan stopped flowing till the ark had been carried over, so the rivers Sutledge and Reyah were said to have rested from their course when Viswámitra wished to cross them in seeking the Soma. This Rishi became identified in the Hindu mind for all time with political priestcraft. On the other hand, Vasishtha became equally famous for his hostility to that power, as well as for his profoundly religious character,--the finest hymns of the Vedas, as to moral feeling, being those that bear his name. The anti-sacerdotal spirit of Vasishtha is especially revealed in a strange satirical hymn in which he ridicules the ceremonial Bráhmans under the guise of a panegyric on frogs. In this composition occur such verses as these:-- 'Like Bráhmans at the Soma-sacrifice of Atirâtra, sitting round a full pond and talking, you, O frogs, celebrate this day of the year when the rainy season begins.
