This book compiles the most lively expressions of nonduality, which is the understanding that existence is one undivided whole and that the daily distinctions we make within this unity are useful, but not ultimately true. The book conveys what nonduality itself is, in a nonacademic style that draws heavily on modern, popular writing on the subject. Also included are spirited passages from major traditions -- Buddhism, Taoism, Hinduism, Christianity, Judaism, and Islam.
