The PHEM pyramids consist of a set of two pyramids of equal size, and both pyramids may contain a rock crystal, depending on the design. To achieve resonance and the emergence of the energy field between the pyramids, they must face each other at the same height, tip to tip. Ideally so that the field can spread over the room or over a part of the room where you often stay (for example, in a seating area, bed, etc.).A placement in closed cabinets or boxes is also possible and does not affect the effect. The recommended maximum distance of the pyramids is about 8 meters. The extension of the energy field is about the same in width as in length and still extends 2-3 meters behind the base plates of the pyramids.
