The Tower indicates that the structures on which we have built our lives need to be torn down, for they no longer support the truth of who we are. This can feel quite alarming, as we may not always be comftrable with abandoning what is familiar in spite of the fact that we know we are on shakey ground.
The Tower hearalds a cathartic period in which anything that has outlived its purpose will simply bye eradicated from our lives. We have a chance to clear out the old and build a new structure that supports our beleifs and vaules.
The lightening flash is symbolic of the light that disples our inner darkness and illuminates a fresh way of being. It is the flash of insight which prompts us to change our lives and get in line with a deeper truth. In so doing, we free ourselves of the conflictof trying to live according to a false beleif system.
Sometimes the tower indicates a radical change of thinking, as we suddenly realize that we can no longer go on the same way, but need to find a more authentic expression of ourselves. We can feel both liberated and alarmed by the experince, depending on how open to change we are.
