These Quartz crystals call themselves “pheris-sun”. They are meant to go to light guides who work with trauma survivors. You will definitely feel the call if you are meant to co-heal with one of these crystals. If you are not currently doing this type of healing work but you are inexplicably and powerfully drawn to one of these crystals, it is likely that you will one day be of assistance to trauma survivors - even if right now it seems out of the realm of possibility.
I share their story in the light log post named for them, pheris-sun
I will listen for the one who is singing for you.
