She graduated from Pomona College in Claremont, CA, where her roommate was now-legendary film producer Lynda Obst.
She addresses both established Christianity and Judaism in statements such as "You've committed no sins, just mistakes." Her earliest renown was for her talks on A Course in Miracles, a step-by-step method for choosing love over fear. She credits her breakthrough to Oprah Winfrey, who invited her on to The Oprah Winfrey Show to discuss Williamson's first book A Return to Love, a book of which Oprah bought one thousand copies. She identifies with Zen Buddhism, that you must empty your mind through enlightenment to truly find God. She is also very good friends with fellow spiritual author Deepak Chopra, with whom she has done lectures.
