This is a very spiritual card, often with sexual overtones.   It can mean that you are in a phase where you are going to be much more physically attractive to others.  The High Priestess is tied to the Moon, to femininity and to inspiration.  This is a time to rely on your intuition and your inner knowledge, rather than your conscious mind or intellect.  Pay attention to your dreams.  Synchronicities are likely now.  When the High Priestess appears, she also often represents a woman that he will want badly, but whom he may not be able to get.  Messages can come to you from all sorts of places.   Make a point to look at spirituality in ways that you have not done before.  Talk to people whose experiences and beliefs are different than your own.  Move out of your comfort zone.  You will be the richer for it.
