Guest post by "Ketira" That's the usual meaning from the Rider-Waite deck. The way I see it is a bit more positive: You've got so much creative energy flowing that you're not sure what to do with it, and if you don't do something, it's going to burst out of you on its own. I guess it's because of the deck I use ("The Witch's Tarot" by Ellen Canon Reed); she decided to depict that card with lightning coming from the inside out & flowing over the Tower as well as into the sky.
