Making a crystal grid can help amplify the power of the chosen crystals. The crystals are placed in a geometric pattern for the specific purpose of directing energy toward a goal, then charged by your energy and intention.
To dive a little more into it, a crystal grid is an arrangement of crystals on a specific geometric shape that focuses the Universal Life Force in a particular way for a particular purpose. The combination and arrangement of crystals works to convert and focus external energy which acts upon it in a variety of forms (e.g. sound, light, electromagnetism) into a unified energy field tuned to a particular need or requirement. The unified energy field that is created allows for vibrational interactions of crystal energies with the aura, spirit, and mind that is consistent with the prescribed healing and wellness design. It concentrates crystal energy into a powerhouse of healing.
