C is for Close. Don't close the door to the past, don't live there, but allow yourself to heal and let go of it in today. So much of our life in today, is rooted in the past, so we need to deal with the issues, memories, guilt, etc. and by doing this, we close the door on our disease.
Our disease may knock, but we don't have to open the door and let it in. We can keep the door closed, one day at a time, using the tools of recovery.
If we don't feed it and fuel the fire, the Light won't shine on the past, but be present in today.
