Here is some background. Godspeed.
Wicca is a neo-pagan, nature-based religion popularized in 1954 by Gerald Gardner, who at the time called it Witchcraft.
For most Wiccans, Wicca is a duotheistic religion worshiping both a God and a Goddess, who are seen as complementary polarities (akin to the Taoist philosophy of yin and yang), and "embodiments of a life-force manifest in nature. Traditionally, the Wiccan God is viewed as the Horned God of nature. The Goddess is usually portrayed as a Triple Goddess with aspects of "Maiden", "Mother" and "Crone".
Beliefs in the after-life vary among Wiccans, although reincarnation is the traditional Wiccan teaching. Wiccans believe in magic that can be manipulated through witchcraft and sorcery. Wiccans cast spells learned through the ritual practices.
Wiccans believe in the five classical elements. The five elements are:
Air, symbolized by east.
Fire, symbolized by south.
Water, symbolized by west.
Earth, symbolized by north.
Spirit, which unites the other four in the center.
Wiccans use a special set of magical tools in their rituals. These can include a broom, cauldron, chalice, wand, Book of Shadows, altar cloth, athame (dagger), boline (sickle shaped knife), candles, crystals, pentacle and/or incense.
Wiccans also follow the Wheel of the Year and celebrate eight festivals known as Sabbat.
One symbol used by the Wicca is the Triquetra derived from the Latin tri- ("three") and quetrus ("cornered"). Its original meaning was simply "triangle" and it has been used to refer to various three-cornered shapes.
