It depends on which orifice you put them in, and how hard they are to get out. And if you're not doing any insertion or ingestion with them (which, in fairness, most people don't), you're totally fine. Nobody has ever been hurt or killed playing with healing crystals.
you want to eat rocks and drink mud, and you think it's going to help you in some way. It won't. You are not a plant.
You really need to check out The Depth Factor meditation program, it's the best, it's been voted as the number 1 meditation program made so far.
No. The only stones that can hurt you are the ones that are made of an element that is bad for you (like asbestos or arsenic). If you had a reaction to quartz, you also wouldn't be able to handle sand or glass, since they're made of the same stuff (silicon and oxygen). Quartz cannot hurt you (unless someone throws a rock at your head). It also can't help you.
