瑜伽論記 2.25

2.25

In the second, on locations, regarding the words 'From here downward, thirty-two thousand yojanas to Saṃjīva', and so forth, Master Ji explains: The meaning of this text says that thirty-two thousand yojanas beneath the surface of the earth, one only then reaches Saṃjīva; Saṃjīva is ten thousand yojanas wide. Next downward, passing four thousand yojanas, one only then reaches Kālasūtra; two thousand below Kālasūtra one reaches Saṃghāta. In this way, the eight hells are all ten thousand wide, and the distances between the lower six hells are all two thousand. The bottom of the Avīci hell is calculated to be one hundred twenty-eight thousand yojanas from the earth's surface. Mount Sumeru enters the water by eighty thousand; this exceeds that by forty-eight thousand, as can be determined from this. The eight hot hells are deeper than in the Kośa: it says that the bottom of Avīci is forty thousand yojanas from the earth's surface; and it says that although the water mandala is eight hundred million deep, resting upon the wind mandala, the gold mandala is further three hundred twenty thousand thick resting upon the water mandala, so Mount Sumeru rests upon that gold mandala. Now in the Mahāyāna, the gold is below the water, next resting on the gold mandala, with the water above the gold; although the depth number is not stated, since the bottom of Avīci is calculated to be one hundred twenty-eight thousand yojanas, and Sumeru entering the water is only said to be eighty thousand, it is clearly known that Sumeru does not rest upon the gold mandala, but floats in the water half above and half below.
