During the dark night the lights all but go off. It is a trial which people nearly always confuse with a curse, even and especially when they’re virtuous.
I’ve written about different dark nights of the soul for nearly a decade. I’ve been through two myself, 18-20 years apart from beginning to end - this is a time loop.
No amount of intellect can impart reason, calm or any sort of peace during a dark night and that is the point. For this reason, God “leaves” us - this is particularly traumatizing when we’ve always had a close connection to God…we do not know life without God.
