Satanists also turn the cross upside-down. This, in itself, does not make the cross or pentagram a Satanic symbol. To members of these traditions, the reversed pentagram is considered highly positive and has no connection to Satanism. We do not feel that the life of another creature is ours to give. Therefore we would never kill an animal in ritual, as we would not consider it a true sacrifice.
Witches believe in the sanctity of all life.
For this reason a large percentage of Witches are vegetarian. Spells, much like prayers, are used to create needed change in one's own life or the life of a loved one. Prayers are a petition to an external Deity to create the change. We as Witches believe that Deity is present in everything, including ourselves. Spells, then, are the channelling of our own divine selves, our own energies, to create the change.
