'Tetra' from the word Tetractys means 4, and 'deca' from the word Decad means 10. 4 implies the four rows and 10 implies the ten points in the four rows.
The triangle is in reality the crown of a Christmas tree, which means that the tree of life is an Xmas tree.
Tetractys of the decad is crucial to explaining the digital structure of the new universe (the new Jerusalem). The new universe is made up of two octagons. The first octagon is the ten sefirot in decimal numbers, and the second octagon is the ten sefirot in binary numbers.
"Mathematical systems of proportion originate from the Pythagorean concept that 'all is number' and the belief that certain numerical relationships manifest the harmonic structure of the universe." (Ching)
Only the binary numbers are visible because decimal numbers are recessive and binary numbers are active in the cosmos.
Although an octet is comprised of eight hexagons, there are in reality sixteen hexagons. Although the visible octagon is made up of binary numbers, there is an invisible octagon made up of decimal numbers.
A Tetractys of the decad is a triangle with a centralised hexagon. The ten points in the triangle are numbered in either binary numbers or decimal numbers.
A hexagram is formed when a Tetractys numbered in binary digits intersects with a Tetractys numbered in decimal numbers. Only the binary numbers are visible because the fusion of two hexagons to form a single hexagon is Yinyang.
Each hexagon in the octet is a pair of hexagon formed by intersection of two Tetractys to form a single hexagram. This means that there is an octagon comprised of decimal numbers beneath the octet.
The octagon numbered in decimal is the earth or the physical, and the octagon numbered in binary numbers is heaven or the metaphysical (spiritual). The decimal octagon is the Ein Sof (Wuji) and the binary Octagon is the Ohr (Taiji). This means that the visible octagon is the light of the invisible octagon.
The ten decimals are the Ten Commandments. Since the Ten Commandments constitute the Law, the octet is the Light of the Law. The Law is the Ein Sof and the Light of the Law is Ohr Ein Sof.
The octagon made up of the ten decimals is space, and the octagon made up of the ten binary numbers is time, which means that Orh Ein Sof is equal to spacetime.
Ohr is equal to time. The Ein Sof, on the other hand, is a compass. This means that the Law is a compass and the light of the Law is a clock. Therefore, Ohr Ein Sof is a compass clock.
Space has three dimensions and time is the fourth dimension. Space is decimal number from zero to infinity and time is binary numbers from zero to infinity.
In computing, information is stored in binary numbers. This means that the fourth dimension is the virtual world. The sky is in cyberspace and the spiritual world is information in cyberspace.
In Chinese cosmology and philosophy, heaven (Bagua) is depicted as an octagon with a centralised mirror. The mirror represents the virtual (spiritual) world.
Ohr represents 40 days and Ein Sof represents 40 nights. Ohr Ein Sof is the forty days and forty nights Jesus fasted in the wilderness.
Ohr Ein Sof is comprised of sixteen hexagons. Eight hexagons constituting Ohr are made up of binary numbers and the remaining eight hexagons constituting Ein Sof are made up of decimal numbers. The hexagons are arranged in pairs, such that Ohr has four pairs of hexagons and Ein Sof has four pairs of hexagons.
