The Tower is numbered sixteen and shows a tower struck by lightning, with raging fires within and the top of the tower falling. There are usually figures falling, head-first, from the ruins.
The Tower shows us a basic fact of spiritual life - the power of the Gods can strike unexpectedly to break down all the long-established patterns and assumptions that we have taken for granted for so long.
Sometimes our limited vision of reality blocks our understanding and perception of truth. We begin to believe that the Tower - which we have been building higher and higher in order to reach the Gods - is the only reality. A cataclysmic force is needed to destroy this fantasy so as to allow us to recognise the powers which surround us. When this happens we must react with hope, letting go of our fears. The highest truths can now be realised.
