Celebration of Demons [PDF ebook] 

The Sinhalese exorcism rituals are perhaps the most complex and the most magnificent in performance still extant. For this second edition, the author has written a new preface and introduction in which he argues that the techniques of healing in Sri Lanka and the aesthetics of this healing cannot be reduced to Western psychoanalytic or psychotherapeutic terms, and develops new and original approaches to ritual and the aesthetic in general.
