Nouwen in Reaching Out is talking about the lack of spiritual directors. I think I would want to include other consultative roles as well which enable our supervision.
“At least part of the reason for this lack .. is that we ourselves do not appeal to our fellow human beings in such a way as to invite them to become our spiritual leaders. If there were no students constantly asking for good teachers, there would be no good teachers. The same is true for spiritual guides. There are many men and women with great spiritual sensitivity whose talents remain dormant because we do not make an appeal to them. Many would, in fact, become wise and holy for our sake if we would invite them to assist us in our search for the prayer of our heart.
“A spiritual director does not need to be more intelligent or more experienced than we are. If is important that he or she accepts our invitation to lead us closer to God and enters with us into the scriptures and into the silence where God speaks to both of us. Often we will discover that those who we ask for help will indeed receive the gift to help us and grow with us toward prayer.” (98)
