‘The koru, which is often used in Māori art as a symbol of creation, is based on the shape of an unfurling fern frond. Its circular shape conveys the idea of perpetual movement, and its inward coil suggests a return to the point of origin. The koru therefore symbolises the way in which life both changes and stays the same.’ 
‘Dancing in a circle is an ancient tradition common to many cultures for marking special occasions, strengthening community and encouraging togetherness. The circle is probably the oldest known dance formation. It is found even today in the community dances of many cultures, including Greek, African, Eastern European, Israeli, Serbian, Irish Celtic, Breton, Catalan, South American and North American Indian. It is also used, in its more meditative form, in worship within various religious traditions, including, for example, the Church of England and other Anglican Churches and the Islamic Hadra dances.’
