觀無量壽佛經義疏 3.32

3.32

"‘Each golden color spreads throughout that jeweled land, transforming everywhere into various different forms: now into vajra pedestals, now into pearl nets, now into clouds of mixed flowers, manifesting at will in the ten directions to perform the Buddha's work.’" The transformations of the colors are threefold: golden pedestals, pearl nets, and flower clouds. There are still other aspects, hence the text says "at will," and so forth. Third, concluding summary.
