Sage is the ultimate cleanser.
Use to cleanse your home, space, physical body. This one is the mama of smudges. Light the end until thin tendrils of smoke appear - use a catching dish. There are many ways to sage but if you adopt a positive clearing the space attitude - use cleansing ritual words (in your mind is fine) such as cleanse, dismiss, dispel as you go, you can't go wrong. We start with ourselves -crown to feet and then from the bottom and work our way to the top of our space.
However you choose to Sage, open windows as you go to release any negativity.
Burn and burn again.
