I began studying ACIM in 1995 after listening to a series of lectures based on Course principles by Marianne
Williamson.
I felt profound changes occur in my life while listening to the lecture series.
I then found a church in SF, CA that offered Course study groups.
The study groups were very helpful in establishing a discipline and answering questions .
ACIM gives one an understanding of the ego's pernicious control over our lives and our ability to find happiness and inner peace and to BEGIN to look at the world through the eyes of forgiveness.
This is an especially good tool and practice for those having gone through 12 step programs .
