'Smudging' is the common name given to the Sacred Smoke Bowl Blessing, a powerful cleansing technique from the Native American tradition. However the burning of herbs for emotional, psychic, and spiritual purification is common practice in many religious, healing, and spiritual traditions. It is a ritual way to cleanse a person, place or an object of negative energies or influences.
