A_058 - I discovered that the presence of minerals nearby can cause concrete and experimentally perceptible effects on our body. Personally I have very few left because the ones I had I gave them away a long time ago. However I have experienced that the quartz as big and long as about 2 fingers side by side that I own, if present near me, over time transforms my consciousness making it become more “aerial” (I find it hard to explain) and makes it almost impossible for me to concentrate to work. I also noticed that in the presence of quartz, watching a documentary on the deep sea I perceived the fish as if they were real fish, while instead looking at an image of “cattivik” or “venom” I had the sensation that it became more and more evil in front of to me. This is explained precisely because quartz lightens our awareness, and therefore since we “perceive by difference” this particular effect is obtained. I suppose these minerals when used in places like spas or meditation centers could lead to considerable benefits. I don't know anything about crystal healing, but these are my personal experiences. I had to remove the quartz from the room because I couldn't concentrate anymore to work, and I discovered it on my skin that had this particular effect. I also found that having mineral bracelets under my pillow caused headaches when trying to sleep.
