A  thousand years of tradition conveyed from Kabbalists from one generation to the next, relates the spiritual use of various amulets and symbols that use permutations of the Holy Name, angels and other words and symbols of scripture. According to the wisdom of the Kabbalists, man and his divine spirit are created of spiritual letters that transmit the aspect of G-D into this world. The intrinsic purpose of the amulet is to restore these aspects, the energy that man blocked due to his/her non-divine behavior. It also  influences man's actions in this world.
