Polymorphism

I've been void and I've been full,
Both exception and the rule;

I've been sightless, I have seen,
Things outside and deep within;

I've been shallow and abyss,
Spitting lips and lips that kiss;

I've been cold, I've been alive,
Queen of flames and humming hive;

I've been wild, I've been tamed,
Beast of burden, wrath unchained;

I've been green and autumn drained,
Waxing dreams and stars that waned;

I've been then and thereafter,
Clouds of storm and rumbling laughter;

Saving breath and tear drowned,
I've been sane and darkness crowned;

I've been dusk and I've been dawn,
I've been raven, I've been swan;

I've been grave and I've been song,
Bleeding knees and deathly strong;

I've been sin and sacrifice,
Sanguine circle, holy vice;

Things unnumbered I have been,
Save the warmth beneath your skin.
