I am keeping this for future about sigil magick
Basically, you just light an incense stick and let the ashes fall and then draw what they look like. Your intention can be set beforehand in your mind. You are lighting this incense so that you can derive a sigil from its ashes for some purpose. If you want you can speak your intention aloud into the smoke or write it on a paper that the ashes will fall on. You could surround your incense with candles, herbs, stones, or other magical items. You could partition your deities for their guidance in the falling of the ashes and/or your interpretation of them. There's really a lot you can do with this if you want to build it into part of a larger ritual but it also works well as background magic. You could light the incense, go about your business and come back to the ashes later. There are many possible choices and they're all yours to make as you see fit. I like to put a white sheet of paper under where the ashes will land because it makes them easier to see. It's also helpful
