Upright
The lightning strike that spares nothing false. Sudden upheaval; the truth arriving all at once.

In astrology
The Tower is the card of Mars — force, drive, conflict. Mars rules Aries and Scorpio.
In the Celtic Cross
Where The Tower falls changes what it says. In the present it names the atmosphere you are in; as the crossing card it shows what lies over the matter; at the foundation it is the root of the situation; in the outcome it is the road ahead if nothing changes. Read the ten positions, or lay a spread and see where it appears.
