Censing and Smudging
When a circle is cast, it is generally cast then purified and then filled. The process of filling the circle is called Censing or Smudging. This is also the time to invite the Ancestors to come to the circle to be with us. Before the circle is cast, light a small brick of charcoal and place it into a censer or insulated bowl to let it get hot.
After the circle is purified, place a small amount of incense onto the charcoal and bless it saying “Blessed be, Child of Fire and Air, that you may make this space sacred.” Carry the censer around the circle slowly, letting the smoke drift around the edges. As you walk, invite the Ancestors to be present in the circle. After people have been brought into the circle, cense each of them as well.
Smudging is the same process but uses a bundle of herbs that are burnt slowly rather than loose herbs.
