For those who don’t or cannot have physical altars:
Remember, you are the altar. Your body is earth, your body heat is fire, the fluids that flow through your body are water, the breath is air and they are all bound by your mind which is an aspect of your spirit.
Here’s mine. It’s hard to see but the woman in the frame on the left is Lilith. I keep all of my incense, tarot cards, and magickal supplies on her side of the altar because she represents the moon, femininity, and magick. On the right is Lucifer and sitting next to him is a bust of Julius Caesar because these things represent the Masculine Luciferian warrior spirit that I often like to channel when working with him. I also have a bunch of silver in the chalice and offering cup because I recently did a money spell.
Here’s a few recent ones, the first is my general altar set-up, it varies depending on who I’m working with. The other two are the mantle over my fireplace and the shelf right next to it, which has offerings and altarpieces that aren’t currently in use.
