There is much talk in Alcoholics Anonymous about spirituality and religion, and the mix between the two. There is a fairly simple reason for this.
Many people who look to get sober have had bad if not traumatic experiences with religious organisations, normally as children, but often as adults as well.
There is a paradox about meditation, in that most types of meditation of themselves are fairly simple to do, but many people find meditation as a practice, or a process, fairly difficult.
Sometimes people put this down to a lack of discipline, or more commonly people simply say that they find meditation so difficult that they cannot do it.
