4.267

日月者。即一四天下，同一日月之所照臨。蘇迷亦云須彌盧，但梵語楚夏耳。此云妙高山，四寶所成，高八萬由旬。

[On] "sun and moon": that is, one set of four continents is illuminated by the same sun and moon. "Sumei" is also called Sumeru, which is merely a difference of transcription between Sanskrit and Chinese. Here it is translated as Mount Sumeru (Myōkō-san), composed of four treasures, eighty thousand yojanas high.
