+745+. In view of such facts as are known it may be surmised that the Mazdean system originated with an Aryan agricultural tribe or body of tribes dwelling near the Caspian Sea, in contact with hostile nomads. These Aryans, we may assume, had the ordinary early apparatus of spirits and nature deities (gods of the sun, water, etc.), but, at the same time, a disposition to concentrate worship on a single god (probably a sky-god), who became the chief tribal deity and was naturally regarded as the source of all things good, the Good Spirit; the phenomena of life led them (as it led some other early peoples) to conceive of a rival spirit, the author of things hostile to life. With economic conditions and intellectual characteristics very different from those of their Hindu brethren, they developed no capacity for organizing an elaborate pantheon--they were practically monolatrous, were content with an all-sufficient Good Spirit (the Bad Spirit being tolerated as an intellectual necessity), gradually subordinated to him such gods as the popular feeling retained, and relegated to the sphere of evil the host of inferior hurtful spirits or gods (_daevas_) whose existence they could not deny.[1292] The religious leaders, representing and enforcing the tribal tendency of thought, in the course of time gave more and more definite shape to the cult; perhaps Zoroaster was a preëminent agent in this movement. Ethical purification, as a matter of course, went hand in hand with cultic organization. The old gods or spirits, associates of the supreme god, became embodiments of moral conceptions, and a ritual of physical and moral purity was worked out. Such may have been the general history of the official system; data for a detailed chronological history are lacking.[1293] +746+. _China._ Chinese religion is characterized by a remarkable restraint in ecclesiastical development: simple religious customs, no native priestly order, few gods, almost no myths. The basis of the popular religion is the usual material, comprising ancestors, spirits (including tutelary spirits), a few departmental gods (of war, of the kitchen, etc.), some of which are said to be deified men. The system is thus nearly the same as that of the central Asiatic Mongolians.[1294]
