When I first bought this stone, I was unable to wear it for more than 5 minutes without feeling dizzy, it was way too strong for me. So I put it away for a while. Then about a year later I was drawn back to it, so I started wearing it and to my surprise I had no problems at all. I felt wonderfully steady and much less wavering in my decisions.
This essence improves your willpower and decisiveness. It clears the mind and clicks it into this decisiveness, so you are more able to actually work out the ideas you have, instead of thinking them up and doing nothing with them. It also helps if you are feeling depressed and may help when you want to quit smoking.
