A crystal controller is a specific seal in which you place underneath a crystal in order to charge, and buying that crystals power to the will of the practitioner. This is so you can focus the kna of the Crystal upon your individual person without needing to keep the crystal on you. Once the crystal controller is beneath the crystal that you want to use all you have to do is put your hand over the crystal, and say “Bai”. This will create a link between you and the crystal using the power of the crystal controller allowing its power to affect you throughout the day until the crystal is removed from the top of the crystal controller.
