A Wiccan may be a Witch, but a witch need not be a Wiccan. Witch' appears to derive from the root 'wicce', which means 'to bend'. I like to play with the ambiguity of this definition. A witch bends like the reed in the wind. She also is one who bends or shapes hir world.
Witches are healers.
This varies, however, among those who engage the healing of individuals, those who work for the healing of all, and those who seek both, or see no essential difference between them. In this way witches may be identified as shamans. Witches TEND to focus more heavily upon certain mythic images than on others. Witches are often ecologists and may apply the principles of ecology in their lives where they feel able. Many are engaged in political activities designed to awaken a sensitivity to issues surrounding plant and animal, the balance of nature, and one's place in nature.
