I think you can be controlled by as much as someone else controls what controls you. EG, you need to eat, someone controls your food, so they control you to the extent that they can get away with before their position of power is compromised. If you think you are free, think again, you are controlled by whatever choices come to you: when two people want A, then someone either gets B or nothing at all. But spiritually people don't really want A, they want freedom, and the foolish think they can get it by imposing tyranny. I have A (freedom), so you have B (tyranny). Or rather, I impose B on you (tyranny), therefore I have A (freedom) by default. Wrong - it's not true freedom, freedom transcends A and B.
