Native Americans revere quartz crystals as the brain cells of Grandmother Earth.
Viewing the Earth as a living organism, primitive stones such as granite and sandstone comprise the skeleton of the organism, the Earth’s crust is the skin.
Vegetation and water channels make up the lifeblood of Earth’s body, and metals and minerals function as glands, nerves and sensory organs.
Quartz crystals, in this worldview, act as the Earth’s brain-mind, through which Spirit, the Universal Mind, maintains communication with all parts of Earth’s organism, equilibrating temperature, moisture levels, and other important variables.
In addition, quartz crystals and other gemstones collectively create an electromagnetic field around the Earth, which is a vital component of the Earth organism’s auric field, and clear quartz crystals, identified with white light, represent the unifying vibrational frequency that harmonizes the seven rainbow rays of Earth’s many varieties of gems and minerals.
Thus any human being who can attune to the power of the quartz crystal becomes attuned with the aura of Grandmother Earth, and obtains the ability to communicate directly with Spiritual worlds.
