Who am I?

I am thunder and I am rain.

Precipitated by life's great pain.

--

I am frost and I am heat.

The friction in love's intimate pleat.

--

I am sickness and I am fine.

On surface, calm, below, turbine.

--

I am colder than death and warmer than life.

I breathe in and am breathless, of unending strife.

--

I am animal and also, machine.

I contort with feeling, and bleep, pristine.

--

I am black as the raven and bright as moon-glow.

I beckon the darkness and cling to light's tow.

--

I am glory and I am hate.

I am fury and I am great.

--

Who am I?

(What am I?)
