Answer:
I run smoother than any rhyme I love to fall but cannot climb.
You use me from your head to your toes. The more I work, the thinner I grow. What am I?
The higher I climb, the hotter I engage. I cannot escape my crystal cage. What am I?
If you have me, you want to share me. Once you share me, you won't have me. What am I?
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.
Brings the sky a lot closer.
