Each grid is customized based on your specific needs. All it takes is a brief phone call to determine what those needs are. Then the proper crystals are selected, arranged into a grid pattern, photographed, and sent to you to view. If the grid feels right to you, then it is fixed to a mirror using clear epoxy, programmed for your specific needs, programmed with a powerful cleansing, and shipped to your door. All you need to do is activate the grid in the space where it will be. The cleansing will release and clear the area of any negative energy and/or entities, and the grid will keep the area clear and protected!
