This is the only difference. Spells are almost invariably used to improve oneself, conditions in one's own life or the life of a loved one. Although the rituals of Wicca vary from individual to individual and from group to group, they tend to share a few common traits. One is a cleansing of the ritual space. These elements are seen as the components of all in nature and also as symbols of those things which define human existence.
Fire stands for willpower and passion.
Water represents intuition, love and most other emotions. Earth is for physical well-being, strength and prosperity. Air symbolizes communication, wisdom and intellect. The pentagram, a five pointed star, with one point upward surrounded by a circle is our religious symbol. It also stands for a human being with arms and legs outstretched engulfed in universal wisdom.
