I am wondering if there is a way to describe this concept in Japanese, or an equivalent phrase.
According to http://en.wikipedia.org/wiki/Crisis_of_faith it is a mostly western concept (if you believe wikipedia anyway).
I am asking in relation to the definition in the first paragraph, not in the religious sense.
This phrase relates to “deciding whether to make (or being forced to make) a choice that goes against ones most basic beliefs.
And in the process, either retain that belief, or drop it in favor of another one. It is this situation that causes the internal conflict.
I do not believe it is directly related to simple inability to make a decision, not knowing what to believe, nor the process of self-discovery in general.”
