Sage used to clear energy in a space. Comes in small drum stick or 4 inch long bundle. Use a match or lighter to ignite your bundle of sage. Hold at about a 45 degree angle pointing the tip down toward the flame. Allow it to burn for about 30 seconds to 1 minute and then blow out. Move around the space you are cleansing making sure to take your time to say your intentions about clearing the negative energy. Also note that sage clears ALL energy in a space and to make sure to fill it with positive energy after.
