At Rainbowâ€™s End is about discovering the treasure of Spirit and finding freedom from addiction. Addiction can be viewed as a key to unlocking the traps you have created in your mind. There is one cause of addiction no matter what form it takes. Your thoughts, beliefs, and feelings create your reality. If you do not like your experience, you need to learn to change your mind. Freedom from addiction is possible and you do not have to spend the rest of your life with a label that limits you. Mary discusses several topics including love, fear, guilt, forgiveness, and many more. She wanted to give the reader a thorough background of the Spiritual knowledge that assisted her in releasing her own mind from the barriers to freedom. Included are references to A COURSE IN MIRACLES, which has been an instrument of healing for her as well as a validation of her own spiritual experiences.
