In the understanding of people who live off their land, water is not a substance but an expression of the live-giving quality of slopes with certain qualities: not to collect water, exactly, but to amass it, like gravity. It is this coming together of forces which is water.
An ocean is a different thing altogether. It, too, is not water, but, if the expression of a water out of the land can teach anything, I think it’s that the image below is identical to the one above, with one exception: in the image above, the ocean below is transformed by the lens of the land into the concentration of energy called water.

This ocean, Gunnar Pointed Out, is the great sea of undifferentiated life and death. They are only sorted by passage through a shore.

In effect, this passage is the same one created by the forms of the land that created the small lake above the sea I showed you above. Here it is again, so you can compare.

The product is the same: you are looking at human life being formed by the land.
