Among the Buddhist priesthood of Thibet, there is a class of Lamas who are astrologers, distinguished by a peculiar dress, and making it their business to tell fortunes, exorcise evil spirits, and so forth. The astrologers "are considered to have intercourse with Sadag," a spirit who is supposed to be "lord of the ground," in which bodies are interred, and who, along with other spirits, requires to be pacified by charms and rites known only to these priests. To prevent them from injuring the dead, the relations offer a price in cattle or money to Sadag; and the astrologers, when satisfied with the amount, undertake the necessary conjuration (B. T., pp. 156, 271). In the Old Testament, this class of unofficial priests is mentioned with the reprobation inspired by rivalry. The Hebrew legislator is at one with the Roman Senate in his desire to expel them from the land. "There shall not be found among you any one that ... useth divination, or an observer of times, or an enchanter, or a witch, or a charmer, or a consultor with familiar spirits, or a wizard, or a necromancer. For all that do these things are an abomination unto the Lord: and because of these abominations the Lord thy God doth drive them out from before thee" (Deut. xviii. 10-12). The very prohibition evinces the existence of the objects against whom it is aimed; and proves that, along with the recognized worship of Jehovah, there existed an unrecognized resort to practices which the sterner adherents of that worship would not permit.
