Book excerpt: "To which extent is ritual involved in the formation of collective and personal identities? What are the mechanisms that are responsible for the (mostly pre-reflexive) constitution of identity in ritual; and - equally important - what are the strategies employed by social actors to actively influence and enhance these constitutive processes? In order to find answers to these essential questions, authors refer to case studies from their respective areas of field research such as Japan, Morocco, Taiwan, Korea, India, and the Azores.
