The Discalced Carmelites are friars and nuns, who dedicate themselves to a life of prayer. The Carmelite nuns live in cloistered (enclosed) monasteries and follow a completely contemplative life. The Carmelite friars, while following a contemplative life, also engage in the promotion of spirituality through their retreat centres, parishes and churches. Lay people, known as the Secular Order, follow their contemplative call in their everyday activities. Devotion to the Virgin Mary is a characteristic of Carmelites and is symbolised by wearing the brown scapular.
