Why Practice A Course in Miracles?

Why should one practice A Course in Miracles? Perhaps one should practice A Course in Miracles if it brings them more peace in their life. Perhaps one should practice A Course in Miracles if it brings them more joy, patience, bliss, happiness, and tranquility. Perhaps the same goes for any other religion. A Course in Miracles that says a universal theology is impossible and unnecessary, but that a universal experience is possible and necessary. Peace.
