One of the seven treasures of the cakravartin king. The precious wheel has one thousand spokes and is the treasure that gives the cakravartin his name, as a king with a “revolving wheel.” This magical wheel floats in the air and travels, followed by the cakravartin king and his army, to the continents they will conquer. In some descriptions the wheel is made of iron, copper, silver, or gold, depending on the degree of his power and the number of the four continents he will conquer. A illustrative passage about the precious wheel is found Toh 95, The Play in Full, 3.3–3.6 (where “cakravartin” is translated as “universal monarch”). See also Toh 4087, the Kāraṇa­prajñapti, folio 112.b.
