The Chariot-key 7- is representative of the Path between Binah, (understanding) the third Sephiroth on the Tree of Life and Geburah (severity) the 5th Sephiroth on the Tree of Life. It is the vehicle that encompasses the Soul on its journey into manifestation, shown by the four Sphinx with different animal faces, each element having four sub-elements (cubed) . The Chariot itself is Kether, the Throne of the Soul, that protects the Soul through its journey through dimensions of universal manifestation. The Chariot itself is thus unmoving and stable while the Red Wheels of Geburah power it through the Universal manifestation. Here the Soul is a golden-solar-warrior, who is protected from the Abyss by the Limitless Light of Kether, a form of energy that the Soul rests on.
The Chariot is ruled by the sign of Cancer, a Water sign (the crab on his helmet) and it is the Water of the High Priestess that is the Fence or Enclosure ( the meaning of Cheth) that protects the Soul in its journey from the Higher to the Lower planes of manifestation. The Soul is the Self of our selves, it is our emanation of the Supreme Spirit Identity from Kether. The Soul being the "Solar Warrior" as shown by the Golden Starred Armor, is lead by the Moon. As our Sun seems to follow the Moon across the sky. The wheels of Geburah (an energy intelligence of Binah the Great Mother) drive the Chariot into Form. Knowing that Binah is the Mother of Form, and is the Feminine Magnetic force of the Universe, we can see that the Chariot is the combination ( the Marriage of Kether-Chokma- Binah that is the Supernal Triangle of the Above.) of Electromagnetic force and the Spirit form that is Soul. So with this in mind we may conclude that the Flowing nature of magnetic mother, protects our Soul from dispersion back into the Limitless light (Dark Father) which is Darkness to us. She is the Vessel, Womb, Grail (that is in the hands of the Golden Knight on the Chariot) that moves our now stable soul-self through the Universe, allowing us a conquest on all planes of energy! That would be the Child of God! This card symbolizes the vision of Ezekiel, wherein the prophet described the appearance of "four living creatures" and that each had four faces, A man, a lion, an ox, and that of an eagle which are the symbols for the elemental forces of the manifested universe. What many of us should now understand is that the Very Severity of Binah, the Great Mother Defends us from dissolution into "Nothingness" as we are her most important "Masters of Form": we are both Master and Masterpiece and as far as She is concerned we are her "Most Beautiful Children" and have been given her Property---The Worlds of Manifestation, as Trusted Keepers! We are Souls who create and operate Self-Image in the Name of Abracadabra (As seen woven into the canopy above the Golden Knight-Soul)-The Vibratory word of the Aeon, The Great Work. The Holy Grail, is the cup which we look into directly, giving form to our thoughts......which become the Self-Awareness of I AM ME. Now I know all this can be confusing, there are so many ways used to describe these cards because they are very old images of invisible forces that are fascinating but almost incomprehensible to our reasoning brain, That is why we must practice raising the Serpent Force within to awaken the normally unused 3/4's of our brain, The Kundalini must flow over and through our brain as the Waters of the High Priestess, before we manifest the comprehension of the Greater Self. Understanding will come to the diligent, for no matter the seeming obfuscation of meanings attributed to them, The Tarot Keys represent truly universal archetypes, Forces and Forms that remain immutable despite the limitations of the worded attempts to describe them. You are comprised of everyone of the 78 images in the Tarot Deck---The Tarot is YOU, not the man-made you who is a reaction to your ruler- defined environment but the Powerful You that is the action that changes environment----To Expand and Liberate the survival mind from its animal existence into the Higher Existence of the Immortal Soul. In the Brain sits the Chariot-resting, while Powered by the Great Mothers Work and sitting quietly on the thrown of Kether, totally protected by the Magnetic Field of the Grail, awaiting the time when the Brain can hear ABRACADABRA--the cypher of the Great Work. With the Ears to Hear, that are developed by Knowing thyself, we can then by the Soul who operates a Power tool--in Mothers Great Garden, rather than a animal looking for its soul, which it will never find, since the finite are definitions from the infinite and are unable to define the infinite in limited thoughts. The Chariot card represents the Solar Warrior Soul who defines being---but is not defined by being. As you can see, there is much to study here....so investigate!
