"Arcane"

Confusing, aren't I? A little bit of a mystery.
A question mark to some, an answer to few.
Hard to put together, hard to clearly see.
My meaning can be obscure to many, mostly you.

I'm an arcane human, but we all flirt on being eccentric.
Divided by emotions and feelings that tear at our souls.
Dancing with all the changes that make our lives tick.
Such as science and history, with religion filling the holes.

Undefined; to be an unwritten book.
A law without principle, a rule without a guide.
An example of freedom for those who dare to look.
To go against the grain, to roll against the tide.

A secret, a foreign text, a language of the dead.
I live my life without trying to stay inside the line.
But sometimes I play by the rules laid out instead.
A mystery to you and me, someone you can't define.
