A Course in Miracles originated in the 1970s through a series of visions experienced by Helen Schucman who meticulously transcribed teachings she claimed were from Jesus Christ. The course seeks a profound shift in perception through forgiveness and acceptance of the oneness of all beings. It challenges conventional spiritual beliefs and encourages reinterpreting religious concepts. While it has gained a global following and integration into therapy, it has also faced criticisms around its complex language and exclusivity.
