There has been a "close association" between the religious and the secular, the spiritual and the temporal in Tibet. The term for this relationship is "chos srid zung 'brel." Traditionally Tibetan lamas have tended to the lay populace by helping them with issues such as protection and prosperity. Common traditions have been the various rites and rituals for mundane ends, such as purifying one's karma, avoiding harm from demonic forces and enemies, and promoting a successful harvest. Divination and exorcism are examples of practices a lama might use for this.
