When you see the Tower, things are about to go terribly wrong. There is a crisis. Unexpected events, lies, infidelity, betrayal will all cause havoc.
I always try to see the positive aspect in cards, but it is difficult here. The best advice of this card is don't fight change. It is time to figure out what is most important in your life. That which is not necessary must be let go.
With very positive cards this will show a new unexpected opportunity.
The positive meaning is that you need to tear down and rebuild, but this is not without personal trials.
Most people, when the Tower shows up, know that something needs to be changed. For those who don't, the counsel is to examine your life. Be prepared for change and don't fight it. For those in a risky lifestyle, watch out. You have been forewarned.
