Choose any two digit number, add together both digits and then subtract the total from your original number.* When you have the final number, look it up on the chart and find the relevant symbol. Concentrate on the symbol. When you have it clearly in your mind, click on the EYE and the symbol you are thinking of will be revealed. *For example, if you chose 28: 2+8=10. 28 minus 10 will give you your answer.
