转轮

(sa) cakravartī, "a ruler the wheels of whose chariot roll everywhere without hindrance." M.W. Revolving wheels; to turn a wheel: also 轉輪王 (轉輪聖王); 輪王; 轉輪聖帝, cf. 斫. The symbol is the (sa) cakra or disc, which is of four kinds indicating the rank, i.e. gold, silver, copper, or iron, the iron (sa) cakravartī ruling over one continent, the south; the copper, over two, east and south: the silver, over three, east, west, and south; the golden being supreme over all the four continents. The term is also applied to the gods over a universe, and to a buddha as universal spiritual king, and as preacher of the supreme doctrine. Only a (sa) cakravartī possesses the 七寳 (sa) saptaratna and 1, 000 sons. The (sa) cakra, or discus, is also a missile used by a (sa) cakravartī for overthrowing his enemies. Its origin is probably the sun with its myriad rays.
