Fear is a feeling, and bravery is a choice.
The only thing a person needs to be brave is fear.
A fearless person can't be brave.
Likewise, a person can't be self-disciplined (a.k.a. free-spirited) without at least some kind of feeling or urge such as fear, anger, hunger, pain, discomfort, etc.
Hunger, anger, fear, pain, and discomfort are like water. Self-discipline (a.k.a. spiritual freedom) is like choosing to swim. Spiritual slavery/imprisonment is like drowning, or at least the feeling of drowning. It's drowning without dying.
It's like waterboarding yourself, which is fine if that's what you choose. To each their own.
We live in heaven, but some choose hell.
In heaven, if you want to waterboard yourself, you get to.
In heaven, even the hell-wishers get their wish.
In this beautiful perfect heavenly world in which we all live, the hell of cowardice is yours for the taking, just like the joy of bravery is.
In this beautiful perfect heavenly world in which we all live, the hell of imaginary slavery is yours for the taking, just as is the graceful joy and invincible inner peace of honest spiritual freedom (a.k.a. self-discipline).

"The mind is a wonderful servant but a terrible master."
I believe spiritual freedom (a.k.a. self-discipline) manifests as bravery, confidence, grace, honesty, love, and inner peace.
