Harmonices Mundi (Harmony of the Worlds) is the musical Axis Mundi defining the harmonious world as a love song
derived from the perfect harmony of astronomical bodies. In 1619, Johannes Kepler postulated that the six known planets at the time have musical characteristics.
The six planets are:
Kepler portrayed the motion of the planets of the Solar System as a singing Choir where Saturn and Jupiter are the basses, Venus and Earth the altos, Mars the tenor, and Mercury the soprano. Kepler believed that though the sound of the song sang by the Choir can't be detected by the ears, it is audible to the soul (mind, Spirit or heart).
"They sang a new song" (Revelation 5:9) "GNT"
It is the song of how God created the harmonious world, and only the one that is in harmony with God will be able to hear this sound and create a harmonious world like God did.
Kepler said that this harmony gives a "very agreeable feeling of bliss, afforded him by this music in the imitation of God."
The term "imitation of God" implies creating a harmonious world and dwelling in it like God created the seventh day and rested on that day.
God created a harmonious world in the beginning of time. The harmonious world is, musically, song of love depicted by the orderly the Solar System. Kepler described the perfect harmony of the six planets as singing in "perfect concord". He said the planets are capable of organising themselves into the perfect harmony as it was in the beginning of time.
The harmonious universe (harmonious world) God created is not audible because it is visible through the knowledge of subjects like astronomy, geometry, music, computer science, physics, mathematics, and the Bible. This means that it is learnt, and you hear the sound when you understand the meaning of the Cosmos expressed by the subjects listed above.
In perfect harmony, the first six planets of the Solar System are the six vertices of a hexagon, the eight planets the eight vertices of an octagon, and their orbits are concentric circles.
The hexagon symbolises resonance, reflected by the three oscillating double bonds of the resonance structure of the benzene ring. The hexagon portrays the first six planets as six different worlds in perfect harmony.
The orbits of the six planets are six concentric circles, and the orbits of the eight planets are eight concentric circles.
The sun and the six orbits of the six planets are the following seven major lines of Latitude:
1. Equator (0 degree)
2. Tropic of Cancer (23.5 degrees north)
3. Tropic of Capricorn (23.5 degrees south)
4. Arctic circle (66.5 degree north)
5. Antarctic circle (66.5 degree south)
6. North Pole (90 degrees north)
7. South Pole (90 degrees south)
The equator embodies the sunlight, and the other six lines of Latitude are the six orbits of the first six planets. These six lines of Latitude are the six points or dots on the six vertices of the hexagon of the Tetractys, and the the Sun is the dot in the centre of the Tetractys.
Numerically, the Sun is equal to 0, Mercury is equal to 1, Venus is equal to 2, Earth is equal to 3, Mars is equal to 4, Jupiter is equal to 5 and Saturn is equal to 6.
Keter (crown) = 0
Chokmah (wisdom) = 1
Binah (understanding) = 2
Da'at (knowledge) = 3
Chesed (kindness) = 4
Gevurah (mercy) = 5
Tiferet (beauty) = 6
Therefore the Sun and the six planets are the seven sefirot listed above. The hexagon, made up of seven sefirot, is equal to eternity because 7 is equal to Tiferet (eternity). This means that God's promise of eternity is fulfilled by the knowledge of the hexagonal resonance structure of the Harmonices Mundi.
Note that sunlight is the equator (a circle) and the Sun is a dot. Also note that the orbits of the planets are circles and the planets are dots. The dots are equal to the circles, such that the planets are depicted as either dots or circles. On Earth they are circles of Latitude, in the hexagon they are dots, and in the Solar System they are equal to their orbits.
Another name for a circle is glory, such that each line of Latitude or orbit is equal to Hod (glory).
Also each dot or point is a seed equal to Yesod. When planted, each seed will sprout into the tree of life (the Axis Mundi).
Christ was a seed planted on the Earth. He germinated into a young plant which grew and became the Cosmos. He grew first to the height of the Solar System, then the Milky Way Galaxy, until he covered the whole universe - until he became Musica Universalis.
