The Tower symbolism -- "The Fire of Heaven"
Palmistry— inner and outer mount of mars, plain of mars
Numerology— 16 (1 + 6 = 7); 7 is an incomposite number which has no divisor other than itself, which is a symbol of it's unity. Pythagoreans call the number 7 "worthy of veneration" & was held to be the number of religion, because man is controlled by 7 celestial spirits. Also called the number of life, fortune, occasion, custody, control, government, judgment, dreams, voices, sounds and "that which leads all things to their end"  Deities who vibrate with the energy of 7 are: AEgis, Osiris, Mars, & Cleo (one of the muses). There are 7 archangels. 7 is also known as the mystic nature of man, consisting of a 3-fold spiritual body & a 4-fold material form. 7 is also the number the Makers of Cosmic law.
Astrology— Ruled by Mars; The archetype of Mars is linked with blood, war, strength, fortification, protection, & standing one's ground (how you fight for things). His vibe is one of breaking away, pioneering, completeing, getting things done, drive & inspiring sacrifice for one's priniciples. Mars signifies things that stimulate, burn, or explode. Mars rules both Aries & Scorpio, & his planetary joy is the 6th. Tuesday is Mars' day of the week. Color: red. Metal: iron. Mars is associated with the 1st & 8th houses.
Kabbalah— Letter “peh” ; meaning “throat, mouth” ; symbolic meaning “speak, word” ; pathway from Hod “splendor” (#8 "communication, expression of energy, reasoning, action, movement") to Netzach “victory” (#7 "strength, determination, concentration") [reasoning to intuitive desire] // The path of Peh is about taking in nourishment (high vibrational energy that activates the spirit) and the passing of speech, Prana Yamas (breathing exercises) & chanting "Ohm" can help on this journey.
Clouds— things seem unclear; didn't see it coming
Crown— the divine nature of man
Falling man & woman— duality; falling from the divine; lower desires -- illusion of the material world; loss of control; no safety net
Fire/flames— alchemy; transmutation; possibility to grow; burns from the top downwards symbolizing that this change is long overdue
Lightning striking from the sun—often thought to represent the transformational energy of scorpio, I would relate it to Uranus -- " the great awakener" -- stripping away all the illusions in life & forcing a recalibration; direct symbol from "god", this change is divine
Tower— (may be a phallic symbol) illusion of materiality; symbolizes the fall of man
Question the tower asks us -- What must I free myself from to release the energy that I AM.
