Genjokoan

Dogen writes something like the following in his Genjokoan: Even though when one looks out, the landscape is round and even, you should know that there are whole worlds, whole jeweled palaces there. The ocean is neither round nor square; its features are infinite in variety. It only looks circular as far as you can see at the time. 
Looking into the arising of the waves, can we see the water? Are the two distinguishable? Looking into the water, will we miss the waves? Are the two the same? The experience of wave is itself water, is itself the ocean great and round. The jeweled palace is itself the water, expressed in so many wondrous facets.
