1"It is impossible and inconceivable, bhikkhus, that two wheel-turning monarchs could arise contemporaneously in one world system; there is no such possibility. [n.156] A "wheel-turning monarch" (rājā cakkavatī) is an ideal king who conquers the lands of the four directions by his righteousness. In AN he is mentioned in AN3.14, AN5.131 –33, AN7.62, and AN7.66. For details, see MN 129.33–47, III 172–77. But it is possible that one wheel-turning monarch might arise in one world system; there is such a possibility."
