The great chasm of the soul and the beginning of other knowledge

Why do we fall into spiritual crisis, and why does this terrifying night of the soul occur? Could it be a reflection of the great darkness that existed before the creation of the world, a still unexplored potential? The great darkness from which everything emerged, including us...!
Isn't spiritual crisis a response to the deep darkness, and doesn't it serve to look into that darkness and give rise to a new vision, a new consciousness?
