What worlds are there herein? I’ll tell you. In these seas of fragrant waters, numerous as atoms in unspeakably many buddha-fields, rest an equal number of world systems. Each world system also contains an equal number of worlds. Those world systems in the ocean of worlds have various resting places, various shapes and forms, various substances and essences, various locations, various entryways, various adornments, various boundaries, various alignments, various similarities, and various powers of maintenance.
