9.14

Nashu (那術). In the scripture it is also written with 述; both are pronounced with the fanqie 食聿 [sh/yu]. It is also called nayouta (nayuta); correctly spoken it is nayuduo (nayuta), which corresponds to one hundred thousand in the Central Land (China). The Guangzan jing says 'hundreds of millions of nayuta kalpas', which is this. According to the Buddhacarita-sūtra, one hundred thousand is called a koṭi, which corresponds to ten million; one hundred koṭis is called an ayuta, which corresponds to one billion; one hundred ayutas is called a nayuta, which corresponds to one hundred billion; this must be the higher system of calculation.
