The answer is psychological, ultimately spiritual.

It's about being able to handle change. It's about letting go of the need for an authority. It's about having the capacity to going on that journey towards real freedom. To have your trust + worldview shattered, and to face all the responsibility that comes with that path of freedom, isn't easy.

It's about being able to say, I wasn't right, I didn't and I don't know. But I'm ready to go on the journey to find out for myself.

That takes courage, that needs awareness of one's own conditioned behavior patterns.
