瑜伽論記 2.28

2.28

Another explanation says: Since the treatise master established the width as ten thousand, one knows that the height is also ten thousand yojanas each. Speaking according to this, entering downward from this level ground, passing an extent of thirty-two thousand, one reaches the Saṃjīva hell; the Saṃjīva hell is ten thousand in length and width; below that ten thousand, separated further by four thousand, the other seven hells reside spread horizontally, and cannot be arranged in vertical succession. Why? Because from the level ground down to the golden ground mandala it is only eighty thousand deep; from the top downward, after subtracting thirty-two thousand, only then are there the eight hells, leaving only forty-eight thousand yojanas of ground. How could it vertically accommodate eight hells each ten thousand yojanas high?
