It goes up, but at the same time goes down. Up toward the sky, and down toward the ground. It's present tense and past tense too, come for a ride, just me and you. What is it?
I cut through evil
like a double edged sword,
And chaos flees at my approach.
Balance I single-handedly upraise,
Through battles fought with heart and mind,
Instead of with my gaze.
What am I?
