瑜伽論記 2.30

2.30

The Saṃmatīya says: They are at the Iron Ring Mountains, facing the wind and water mandalas, struck by cold air devoid of the light of the sun and moon. Bei says: Going downward again from the level ground, passing an extent of thirty-three thousand, there is the first cold hell; from here, separated further by two thousand yojanas, the seven hells are each two thousand high, stacked vertically. Another explanation says: The eight cold hells are each ten thousand high and wide; entering the earth from here, passing an extent of thirty-two thousand, there is the first cold hell; downward, separated further by two thousand yojanas, there are seven cold hells situated around the perimeter. As for the three such as blazing, they distinguish partial, predominant, and complete; 'a single mass' means that one does not see bodily form, but only sees the appearance of a mass of fire.
