I assume the savage spheres are the raindrops pelting the trees during a heavy down pour. I'm under the impression that you prayed for a passion bordering on violence that would simultaneously saturate and sustain you. That's what I gather from this image. My only nitpicks might be the formatting, but the write itself is quite good.
I write at least one a day. Many don't make it onto ES. At least not until after a bunch of tweaking. But some I just put up right away and see how they "do".
I like this piece a lot. The only distraction for me was the use of caps at the beginning of each line.
I love "Savage seraphim spheres". That's some good stuff.
Interesting that these fiery creatures would feed the roots of trees. . . strange image. I expected that they would feed on the roots. Or that they would not crash into the trees only then to feed the roots.
And then the idea of the speaker praying for rain . . . this is very complex for such a short piece.
