Central to the teachings of "A Class in Miracles" is the idea of forgiveness as the important thing to internal peace and salvation. Unlike main-stream notions of forgiveness, which frequently include pardoning others for observed wrongdoings, the Course emphasizes forgiveness as a way of delivering the self-imposed barriers to love and healing. By relinquishing grievances and judgments, individuals may free themselves from the bondage of the ego and feel the transformative energy of heavenly love.

The Book for Pupils comprises 365 classes, one for each day of the season, built to aid an organized process of internal therapeutic and religious awakening. Each lesson offers a particular theme or concept to contemplate, followed by practical exercises and meditations. Through spiritual movie training, pupils figure out how to cultivate a state of mindfulness, attuning their thoughts to the advice of the Holy Heart and uncovering the truth of their heavenly nature.

The Guide for Teachers serves as a supplementary information for people who desire to deepen their comprehension of the Program and share their teachings with others. It handles common questions and considerations that could arise during the study of "A Program in Miracles," providing ideas into the process of religious teaching and learning. By providing advice on how best to extend love and forgiveness to the others, the Manual empowers individuals to become routes of healing and change in the world.

At the heart of "A Program in Miracles" may be the acceptance that correct salvation arises from a change in perception—from anxiety to love, from divorce to unity. By transcending the ego's limits and aligning with the divine quality within, persons may awaken with their natural wholeness and reclaim their divine inheritance as children of God. Through the practice of forgiveness and the willingness to submit the ego's illusions, students of the Course can experience miracles—wonders of healing, miracles of love, and miracles of transformation.
