I once, many years ago, had the most wonderful, but brief, taster session of crystal healing. 
This was even more wonderful as the lady that conducted this was blind.Strange comment I hear you say! but I feel that when one sense is restricted, the sixth sense becomes very strong. When I lost a large percentage of my hearing in my right ear due to an illness in 1993, I found that my sixth sense started to grow stronger to compensate.
As I was seated on a chair, she selected a crystal from her tray of crystals, holding it, she moved her hands over my body, in a wave movement, speaking, telling me what she could sense, what she was clearing, and healing.Next she would replace the crystal back on the tray, collecting another for another part of my body, feeling her way, what she was drawn to. At the end of the short session  I ended up feeling very relaxed, and somewhat revitalized. 
 Crystal healers work with the elements of crystals, as each crystal has its own healing property, they chose the crystal that they are drawn to,not necessarily the crystal that is renowned for healing a particular ailment, guided by their own intuition.
Crystal healing is a very popular form of healing. Give this type of healing a try, or perhaps if you are looking to work holistically, you could try this as your new profession?!
