瑜伽論記 2.26

2.26

Venerable Bei explains, saying: Now relying on this treatise, the heights of each of the upper eight hells are four thousand yojanas; therefore from this continent to the top of the Saṃjīva hell there are thirty-two thousand yojanas, and down through its own extent is four thousand yojanas; the remaining seven hells reside downward, each occupying four thousand, totaling eight times four thousand, which makes thirty-two thousand yojanas; from Saṃjīva upward there are further thirty-two thousand yojanas, totaling sixty-four thousand yojanas, leaving sixteen thousand yojanas before reaching the golden ground.
