There are at least two types of higher power in a person's life. The first one is the one that's taught to a person in their youth. It's not a guaranty that we keep that one as we mature.

The second source of divine power is the one we come to acknowledge as we attain our own wisdom. In this episode, Angel describes the one that was force-fed to her, contrasting that one with the high power, which she calls "Great Spirit". The second is an integral part of her recovery, and the peace it has brought into her life!
