2.30

正量部云：在鐵輪山臨風水輪，無日月光冷氣所衝。備云：還從平地向下過三萬三千量有初寒獄，從此復隔二千由旬，七地獄高各二千上下如重。又解：八寒地獄高廣各十千，從此入地過三萬二千量有初寒獄，向下復隔二千由旬有七寒獄周圍傍住，燒然等三，少分多分全分別也，一聚者不見形容，但見一聚火相故。

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.
