When an old river produces a new wave, it is in fact the river, though they call it a wave.

I saw the one in the form of an ocean bursting into waves, keeping some of them and destroying others. There were circles of creatures, large and small; Some of them were happy: they displayed the mercy of the one in varying degrees according to the expanse of their circles and their righteousness. Others were unhappy: they showed the wrath of the one in varying degrees according to the narrowness of their circles and their wickedness.

The ocean as sustainer was sustaining some, and as destroyer was destroying others, and as producer of waves was creating new waves.
