Air is the thinking element, communication, messages, and thought come from this energy. Use Air energy to communicate with spirit.
Incense magic is the air energy in physical manifestation. In this area, you use what you like best.
I had sage burning when I began my meditation practice. Because of that when I smell Sage now, I can quickly get into the meditative state. So it is very important to me.
Smell will trigger memories, so be sure to use what you like and what feels best for you.
Sage Smudging is a good thing to do to keep your space clear. Burn some sage leaves and them blow them out, like you do with incense you do not need to use a huge Sage stick for this, just a few leaves you can just hold the end of them or put them into a bowl. Then blow the smoke into the area you want to clear. Sage clears out drifting bits of unproductive energy. And it infuses the area with clarity that creates a sacred space.
For ceremony work, Sage is the thing as far as I am concerned. I have tried others and they don’t seem to have the same effect. But everyone is different and if something else works for you, by all means use it.
Tobacco is not to be forgotten as its smoke was the essence of the Pipe ceremony that takes prayers to spirit.
When you are creating a sacred space, do not forget the air element. It is important in order to maintain balance.
