An eclectic Wiccan as the term implies, doesn’t follow any strict traditional guidelines. Instead they practice the beliefs that suit them best. They often mix traditions to find that which most suits their own stance on religion or personal beliefs.
They practice whatever magick they consider obtains the best results, and study those parts of any religion that best suit their lifestyles. This is mostly of modern origin and rather New Age; where previously most Wiccan traditions had more restricting boundaries. The eclectic tradition marks witchcraft’s expansion into a patchwork quilt of various beliefs and theories.
