楞伽阿跋多羅寶經註解 1.197

1.197

此問世界形相。須彌者，妙高山也，統一四天下，一日月所繞。蓮華者，華藏世界也。師子世界於諸剎土最勝。世界如器，有側有覆、有仰有橫。因陀羅網即帝網，網有千珠，珠光交映，喻世界重重無盡。

This asks about the shapes and appearances of worlds. "Sumeru" is the Wonderfully High Mountain; it unites the four continents, encircled by a single sun and moon. "Lotus" refers to the Padmagarbha world. The lion-shaped world is the most supreme among realms. Worlds are like vessels: some are tilted, some overturned, some facing upwards, and some horizontal. "Indra's net" is the net of Śakra; the net has a thousand jewels whose lights interreflect, illustrating the multiply layered and endless nature of worlds.
