Those Four Elements

When I sit to start my thinking,
My thoughts, I find, are never sinking,
Sometimes they blow here and there,
To and fro without a care.

And at other times, my head is solid,
And my face reflects my emotions: stolid.
Unmovable, I am, like the earth,
And stubborn, with a movement's dearth.

I have within me a saving grace,
And that's when I emote, I can blaze.
I burn with furvor, furiously bright,
And can prove my feelings from day to night.

But too I can be calm as the sea,
Always in motion, but hardly moved, me.
My heart is quenched, and even drowned,
Or bobbing ever, my fleshy pound.

Be it wind or be it stone,
Or fire hot or water cold,
My thoughts will be on you, the one,
And my feelings yours ever after old.
