In the centre of A Class in Wonders lies a profound philosophy that tries to steer individuals towards a significant shift in belief and consciousness. The primary teachings stress the attainment of inner peace, forgiveness, and the recognition of the oneness of all creation. ACIM occurs as an organized and extensive curriculum, consisting of a Text, Book for Students, and Guide for Teachers. The Text offers the theoretical foundation, the Book presents useful workouts for everyday program, and the Information acts as helpful information for people who elect to become educators of the course.

The main tenet of A Course in Wonders may be the variance between the pride and the real Self. The vanity, in accordance with ACIM, could be the fake self that arises from the opinion in separation from Lord and others. It's the foundation of concern, judgment, and conflict. The actual Home, on one other hand, is the divine quality within every personal, representing enjoy, peace, and unity. ACIM asserts that the trip toward self-realization and spiritual awareness involves the dismantling of the pride and the acceptance of one's correct personality as a spiritual being.

Forgiveness keeps a pivotal position in the teachings of ACIM. Unlike traditional notions of forgiveness, which regularly require pardoning the perceived wrongdoings of the others, ACIM's forgiveness is a procedure of publishing judgments and grievances presented against oneself and others. It is really a recognition that the observed sins and mistakes are rooted in the illusions of the ego, and through forgiveness, it's possible to see beyond these illusions to the inherent purity and divinity in every being. ACIM teaches that forgiveness is a way to inner peace and the key to undoing the ego's hold on tight the mind.

The Workbook for Pupils, comprising 365 instructions, is a functional manual designed to lead the student through a transformative process. Each training targets a particular design, guiding the practitioner to apply the teachings within their day-to-day lives. The instructions protect a wide variety of topics, including notion, forgiveness, love, and the type of reality. The repetitive nature of the Workbook is intentional, reinforcing the idea that consistent training is required for the change of consciousness.
