Ok - Now what do I do with it?
Hehe - good question. In many cases, a well charged crystal will simply shift the vibration of any space it finds itself in. So the first way to use it, is to simply place it in a room you find yourself in often. (ie. In your bedroom, your car, or kitchen)
Another way to work with them, is to hold them. Simply hold them. Hold them while you're reading, or meditating, or having a phone chat with a friend. This is how you get to know it, while also receive it's healing benefits. Experiment and observe.
In addition, you can try one of my favourite applications, which is to place stones on your chakras, or on points of your body that are hurting. I have used crystals successfully to treat stomach-aches and menstrual cramps. This process is intuitive. If I'm hurting, I will simply grab the first stone that comes to mind, and place it on the part of my body that is in pain. Sometimes this works magic, and sometimes it only helps a bit. Again, experiment and observe.
I've laid out very simple ways to use crystals - there are books and courses that deal with crystal healing - but for now, it's best to start intuitively and simply. Just have them around, hold them, and use them when you're in pain. Make up your own ways to use them.
Charge your drinking water, or bring them into the bath. Plant them in your garden, or leave them under your pillow at night.
Have fun, you can't mess up, just go with the flow, your intuition, and know that once you start working with crystals, you will have them in your life for years to come.
