Are all crystals used for protection useless and or harmful?

For the most part this is true. The exception is with the quartz crystal strategy we taught you, to have a dialogue with the crystal to request its help as a warning for incursion of any dark energy, and to sound the alarm to request divine assistance in that eventuality. This strategy does work brilliantly and is the inspiration for the practice of putting out an array of crystals surrounding one’s living space or sacred space used for meditation and other intuitive work. The key is to use the right mineral. Quartz is best for this. Those minerals associated with protection from darkness are more than likely a misdirection and misunderstanding that will get people into trouble, as we recently shared with you concerning selenite.
