Building a tower to try and reach heaven is a blasphemy punished by the inability to understand or empathize with each other (BABEL). Blowing apart the Tower and destroying the rigid and limiting structures of the mind allows a reunion with the group soul, from which all energy derives. Its a mistake to think God (energy) is out there or up there when in fact it is inside us all. When the mind is blown (flushed clean by a strong flow of energy) it is possible to see and feel that life force moving through us and through everything.
Artificial structures (the physical manifestations of the hive mind) are built to control and contain the individual. They are symbols of a temporal power that has cut itself off from its true source and so is inherently doomed.
The Tower is a frightening card on a grand scale, speaking of war and destruction and the all seeing control of those who lust for power. But on the personal level it is quite a helpful glyph showing the means by which a mind may escape the prison of its own construction. A mind that has liberated itself cannot be controlled by anyone. And the eye then becomes a symbol for the awakened all seeing consciousness.
The Dove and the Serpent are symbollic of the dual nature of energy (which is also love). There can be no ecstasy without agony, and intense suffering increases the ability to heal and feel joy. Everything comes in waves, up and down.
“Nor let the fools mistake love; for there are love and love. There is the dove, and there is the serpent. Choose ye well.”
–Aleister Crowley, The Book of the Law, 57
I think the serpent is delusion and projection, which seems to be what passes for love most of the time. Love as a need to possess its object, which is just thinly veiled will to power.
