White sage is a traditional smudge for for spiritual and energetic cleansing and mixed with juniper which is great for for a safe, positive healing space.
Light the sage and set the burning leaves onto a non-flammable container (like a traditional abalone shell)
Wave a feather above, to further enhance and fan the smoldering sacred scents into the air, while saying a personal mantra and envision the space being cleansed.
Open windows and doors and ensure the smoke is waved in all corners of the room. Make sure the smudge stick is put out when complete and do not leave unattended while burning.
