Facing the darkness

Been reading "Learning and Being" chapter 5 whiie having a bath. It wasn't mentioned but since getting out the thought came that as I persue the PCA there will come a period of darkness as I discover more about myself, who I am, who I am becoming. I don't really want to be different from who I am now, except more patient, more accepting of others, more loving. Perhaps the darkness is passed through to get to the light of being as I desire?
