Key 16 The Tower. Mars rules this card in which the keyword is awakening. This comes as a clear flash of understanding, a bolt from the blue bringing awareness of the true nature of the self. What inspires fear in the mind of the ignorant liberates the enlightened, just as electricity frightens the primitive but is used constructively by the knowledgeable. A flash of lightning is another symbol of the electrical serpent force, or the kundalini, the Mars force in the body.
The Tower, also called the Lightning-struck Tower, is the house of God, or the human body. It was also referred to as the Tower of Babel (Babble means confusion of understanding.) Lightning strikes the crown or head or place of understanding and knocks the man and woman out of the tower. This analogy depicts erroneous ideas being knocked out of the two parts of mind, conscious and subconscious, by the lightning of true understanding.
The twenty-two yods or tongues of flame represent the twenty-two letters in this alphabet. These tongues of flame also refer to key 9, where the one yod is the Hermit, representing the response to primal will. When we respond to the primal will, we receive a flash of illumination which bears a message that awakens us to our true source.
