"These defects grow in the dark and die in the light of exposure."
Basic Text p.31
The Fifth Step asks us to share our true nature with God, with ourselves, and with another human being. It doesn't encourage us to tell everyone every little secret about ourselves. It doesn't ask us to disclose to the whole world every shameful or frightening thought we've ever had. Step Five simply suggests that our secrets cause us more harm than good when we keep them completely to ourselves.
