"Metal wheel" "gold wheel." （1） From Buddho-Indian mytho-cosmology. Above the primordial void are three layered wheels， which eventually give support to the earth. The lowest is the "wind wheel." This is followed by the water wheel and metal wheel. （ka^n~cana-man!d!ala） （2） As an abbreviation of 金轮宝， the first of the seven treasures （轮、象、马、珠、主藏臣、玉女、主兵臣） of the wheel-turning sage kings （转轮圣王）. In this case there are four wheels （cakra， or rings， which are made of gold， silver， copper and iron. The "wheel turning King" takes his name from the fact that he takes the uppermost wheel and on it distributes the four great continents and their respective contents. This thousand-spoked golden wheel treasure， originally a symbol of the ruling authority of the Wheel Turning King is borrowed into Buddhism， where it is used to symbolize the authority of the King of the Dharma （the Buddha）， and his exposition of true reality comes to be referred to as "turning the wheel of the dharma." Because of this， in Buddhist iconography and art， the Buddha is depicted as having the physical marks of thousand spoke wheels on the palms of his hands and the undersides of his feet. （3） The Golden Wheel Sage King.
