This piece is not the original piece of the Compte Du Saint Germain; however, the power comes from his original powers. He taught not only the magic of change material objects into gold and other items of wealth, but also the ability transform the body into its purest shape. This is what the magic in this piece is designed to do-- give you an awakening that will allow you to experience your body as a whole, not just the state in which you currently exist. To do this, you undergo a transformation that will give you the knowledge of all your previous lives.
Each person has had multiple lives and multiple existences that they have endured through eternal history. Each history has provided a different set of powers and knowledge that made the person who they were to become in the said lifecycle. This power and knowledge is then repressed into a person's core soul and the only way to ever access this power and knowledge is to re-awaken all of their previous existence. This piece creates a reflection that will allow you to know all of you previous forms of existence. By this I mean that you will be able to see all of your previous existences and the powers, magic, and knowledge associated with each.
Perhaps in your past life you were an Egyptian sorcerer or a Mayan Highpriest of the Temple, a Celtic Druid, or a Germanic wizard. Whatever you have been will come full circle and you will be able to unlock all of your past lives, which will bring you some type of magic and ability. What kind, I supposed, will be up you because everyone is different.
