楞伽阿跋多羅寶經註解 1.199

1.199

此亦問世界形相不同，或諸寶所成，或狀如箜篌、如鼓、如華，或無日月所照，何因而致。

This also asks about the differences in the shapes and appearances of worlds: why some are formed of various jewels, some shaped like harps, drums, or flowers, and some unilluminated by the sun and moon, and from what causes they are brought about.
