Here are some pictures from Acorn Grove's witchcraft rituals. We're an occult collective that combines Wicca, Thelema and modern witchcraft.
Let the salt of earth admonish the water to bear the virtue of the great sea
Let the fire and air make sweet the world
Here are some full pics of the altars. These are folding tables from the top floor of the liberal church where we meet.
Some weird ingredients you might see are an anointing oil that says Obama and a small spritz bottle that is from the hair store. You can also use Hoyts Cologne or any other Murray Lanman cologne such as rose or orange. The way to use this (lustral water) is to water it down with normal water or moon water, charged in the full moon. "The Lustral Water! Let thy flood Cleanse me, lymph, marrow, & blood!" - Liber 671
There's a fan that represents air. A scented attar oil is used during witchcraft rituals to represent the "holy oil of aspiration", as well as the element of fire. The reason these items are placed on the altar is to represent the four majors, or elements that make up the universe. In modern times we would call these solids, liquids, gas and energy but it's the same thing. By symbolically creating the universe on a table witches believe we can effect change in the macrocosm from the microcosm outward.
