The use of sage is for healing. The smoke is used to bless, cleanse and heal the person or object being smudged. Sage is used to ‘wash off’ the outside world when one enters ceremony or other sacred space.
Smudging can help combat this negativity, clear the energy in your field, and help you start anew. Smudging is an ancient ceremony in which you burn sacred plants, such as sage, to allow the smoke to clear and bless a space.
