Dr. Schucman was a very gifted psychic, albeit a reluctant one. She struggled with her amazing psychic abilities, her powerful intellect and her position as a psychologist at Columbia University.
Reading anything about Helen or by Helen, I learn a lot about being psychic; being a channel; the nature of reality; past lives; soul connections over lifetimes, the way the human personality/ego integrates spirit and matter; the way we hear spirit, and much more.
This autobiography comes from Foundation for Inner Peace; https://acim.org/ On their website are many resources. They post A Course in Miracles daily lessons in audio as well as written form. Very beautiful and valuable website.
Miracle Distribution Center: https://www.miraclecenter.org/wp/, has additional books, information, resources and workshops. They also have free Livestream talks on A Course in Miracles.
I also have here the book Absence from Felicity by Kenneth Wapnick. I find it excellent. He has spent a lot of time with Helen and helped edit A Course in Miracles. His views on the entire process of the production of A Course in Miracles, his relationship with Helen and his understanding of A Course in Miracles are priceless.
