Interpretation of any Tarot card or spread must take into account the reader, the querent and the context. That said, here’s my general interpretation of The Tower from the Rider Waite Tarot deck and its meaning.
Reading The Card – Meaning
Like Death, The Tower symbolises the end of the current state. Unlike Death it does not necessarily promise the birth of something new. If badly aspected this can be the worst card of the Tarot deck.
The Tower always indicates upheavel, possibly chaos, loss and destruction. Its effects are never pleasant and can be painful.
The card illustrates lightning striking the Tower. The lightning cannot be avoided, the destruction it brings is inevitable. All we can do is attempt to survive and rebuild.
The Tower brings sudden, severe change. It is up to us whether or not we harness that opportunity to build a bigger, better Tower for the future.
When the Tower appears in a Tarot spread it represents sudden and possibly violent change, disruption or loss. This loss must be interpreted with regard to the other cards in the spread to determine who will be struck be the lightning and how they will cope with the experience.
That which does not kill us makes us stronger – or does it?
