Amyel- The Mythic deck was what really helped me understand the Star card, too. Although perhaps I interpret the Mythic Star card a little differently. As I understand the myth, it was inevitable and perhaps necessary for pandora to open the box. Yes, it released the plagues, but there would be no hope without it either. I've oftne seen Pandora's box as being equivalent to the tree of knowledge of good and evil in genesis. Adam and Eve were supposed to eat from it. It's part of the loss of innocence necessary for growing up. that's not to say we can't maintain some sense of innocence as we get older, but that we should keep our troubles "swept under the rug" or (in this case) "locked up in a box." The need tobe brought to the surface and dealt with, though it may be painful at first. Only by acknowledging the good and the evil of what we have been through can we hope to make true sense of our lives. As children, we are often overwhelmed by traumas and for survival's sake need to lock up our feelings. However, keeping these feelings locked up as we get older only ends up causing us even more pain in the long run.
To this day I remember (and probably always will) the first reading I did with this deck. It was for a friend who had some serious problems that she really needed some counseling for. I had tried to tell her this, but she just kept saying she would be okay; and yet these problems kept affecting her. Well, she shuffled, cut, and then I dealt out the CC. Sure enough the Star card came up in the final outcome position (and I was sh--ting in my pants). I knew exactly what was being said, but was going throught the other cards trying to think of some other way to interpret that card, fearing that she would think I was just setting her up, since I had told her those same things before. Well, I couldn't think of any other meaning that fit and gave it to her straight, telling her that she needed to explore the darkness to find the bright light buried deep within it. She actually took it pretty well, although I wonder if she was just being nice.
There are other meaning to this card that I do use, depending on the other card in the reading. Most of them however can be summed up witht he word "hope."
One other is a meaning I use for Star cards in deck where the woman pouring the water into the river has the cup or chalice held in such a way that it is blocking her private area. Often this card in these decks comes up in postion 7 of the CC (which I use as indicating fears) reversed when I'm reading for middle aged women. I look as indicating menopause and their fear of growing older and not being able to do all the things they used to. If this same card reversed came up in a reading for a woman who was young and skinny I'd look at it as amenorrhea (which is probably caused by an eating disorder). Fortunately, this scenario has not occured in any of my readings yet (fingers-crossed).
Hope this helps,
Love, understanding, and compassion,
