"A Course in Miracles" is a spiritual self-study program that aims to help individuals achieve inner peace and personal transformation. It was written by Helen Schucman, a psychologist, and was first published in 1976. The course consists of a text, a workbook for students, and a manual for teachers, focusing on the principles of forgiveness, love, and the nature of reality. The teachings emphasize that true change comes from within and that our perceptions shape our experiences. By practicing the lessons in the workbook, students learn to shift their thinking from fear to love, ultimately seeking to recognize the divine in themselves and others.
