During ritual practices, which are often staged in a sacred circle, Wiccans cast spells or "workings" intended to bring about real changes in the physical world. Common Wiccan spells include those used for healing, for protection, fertility, or to banish negative influences. Many early Wiccans, such as Alex Sanders, Sybil Leek and Alex Winfield, referred to their own magic as "white magic", which contrasted with "black magic", which they associated with evil and Satanism. Sanders also used the similar terminology of "left hand path" to describe malevolent magic, and "right hand path" to describe magic performed with good intentions; terminology that had originated with the occultist Helena Blavatsky in the 19th century. Some modern Wiccans, however, have stopped using the white-black magic and left-right hand path dichotomies, arguing for instance that the colour black should not necessarily have any associations with evil.
