Crystal Healing With Real Crystals
If you have crystals, you can apply them as healing tools. It would more than suffice to have only quartz crystals, because you can "tell" them that they can act as if crystals of any other color. But, if you have any other crystal, from amethyst to charoit to agate to rodonite to amber to... all of that can be very useful.The most obvious way of using crystals is to put them on certain parts of the body. If the color of the crystal matches the color of the nearby chakra, so much the better. Crystals are known to balance the chakras of their own color, and once the chakras are balanced, any other healing will be more successful.
You can also put the crystals near you. There are different patterns -- the star of David, the double star of David, the circle etc. and you should experiment to see what is best in your situation. In certain cases, this means you should have 12 crystals around the body. Again, quartz is the cheapest and most readily available; and for some crystal healers, it is not the best but the only kind of crystals needed for healing.
After you put the crystals around you, lie down and be still. You should clearly feel the energies of the crystals working and after 15 or more minutes, the shift in your energies should be noticeable.
For problems of uro-genital system, the main chakras responsible would be the first and the second chakras, although it pays to have all the chakras balanced -- it really is the minimum for health, you know.
