So after Sarah's gotten through the labyrinth, defeated the Goblin King's goblin army with her muppet friends, etc., she has a final showdown with him in this awesome inverted/upside down/winding staircase scene.
But in the end he still tries to get Sarah to give in. "Just fear me, love me, do as I say and I will be your slave," he beckons. The whole movie she's been trying to remember this certain line from a fantasy play (also called Labyrinth) before entering the Goblin City. And she finally remembers it (and sorry, she does briefly use a mild expletive. I forgot about that part. Please skip it if it would offend you):
The Goblin King's game is up. The facade melts away. The key to her success the whole time was realizing the Goblin King actually had no power over her!
In a way, I sort of feel like Sarah after she remembers her line. There are negative things and icky lies that constantly work to bring me down. But I realized anew today, they have no power over me. Not unless I allow them to. To the Goblin Kings, Lord Henrys, Satan and his lying lies: You have no power over me.
