Book excerpt: Many rituals and festivals take place in public, meaning that such expressions of faith are societal as well as individual forms of human behaviour. The similarity in the general patterns of rituals and festivals across cultures and religions is striking. For example, most cultures and religions mark major life-course transitions such as birth, marriage, and death with public ritual expressions, and numerous festivals are tied to food-producing activities such as planting and harvesting. Where religions and societies vary is in the meanings associated with ritual behaviour and the specific forms those behaviours take.
