Like meeting a new person, you may not be resonant with a specific type of crystal. For myself, I tend to connect more with crystals that have base element inclusions, iron, etc. Those things that are more on the “decayed” side of the elemental chart, but others would perhaps vibe with more “refined” or “energetic” crystals. They each have an impact on people.
Now in fact, crystals can be used to serve as an additional pair of eyes when dealing with places of power, or just dealing with your personal space. They can also be brought into entrainment to radiate an effect you would have fill your home. A “positive” haunting in a way.
If you would expand your awareness in general, find a crystal you feel a sense of rapport with. It might seem strange, but you will feel the same rapport as with a person. It will just feel good to be with the crystal. As you work with it more (and meditation sensations with it help), it will begin to communicate with you. Even if only on that subconscious level that lets you know, say “My mom isn’t well”. That root sense of how someone is. Ever experience that sensation? Well, with crystals it is different. They don’t have the biological signals, and that root level of consciousness link and communication is much more natural for them. For some it may seem fleeting. They are fast. This is why meditating with your crystal helps. You and it move into a closer energy link. Closer to the same level.
Hold the crystal as you meditate. Then as you carry it, it will give feedback about the environment. It won’t say “I’m not well”, it will say “This place is good for us” or “This place is negative”. Some people pick a crystal to carry in their pocket during the day. They may feel from time to time like they sense something sort of strangely in a second hand way.
Your thoughts are welcome. Be well friends.
