introduction
trinity
“The three come forth from the one. One is in three and stands between two, forming a triad from which has proceeded everything; so that One is all and all is One.” - Zohar
“God never passes nine in any creative expression nor does any phenomena in Nature ever exceed the principle upon which your breathing, or heartbeat is based. Anything in Nature, or in your life's problems, which might have one million parts and one million complexities, if taken apart, will be found to constitute one simple principle of three elements. God multiplies these three by three to make nine, but never more than that. So if you can understand the principle of the basic three, and if you can multiply that three by three, you can become the greatest chemist, metallurgist, electrical engineer, poet, painter, philosopher or inventor in the whole world if no one but you in the world did understand it. This basic THREE, which cannot be added to nor subtracted from, will hereinafter be referred to as THE DIVINE TRINITY.” - Walter Russell
“If you knew the magnificence of the 3, 6 and 9, you would have a key to the universe.” – Nikola Tesla

Trefoil knot
This is the simplest example of a nontrivial knot. It can be created by cutting the circle and connecting the two line-ends after one knot-movement.
Its a beautiful, hypnotic example of complex form made from a basic geometry. Nature is simple in its base logic, but infinitely complex in its effects. The whole physical universe is one connected line of (Mind-induced polarized) energy flows formed into a beautiful, hyper-complex knot-shape. Complete separation is an illusion - even
birth and death are only changes in the polarity of Life energy.

“In the production of finite existence the first act was the evolution of the Memra, or the Word, which was the first point in the descending series of beings, and from whom in nine other degrees of manifestation emanated those forms which at once compose the universe and express the attributes and presence of its eternal ruler. To these nine forms is given the common name of Sephiroth, signifying Splendors. The whole or some of these Sephiroth constitute the universe, the manifestation of God, (…) The primordial essence is before all things. In his abstract and eternal nature and condition he is incomprehensible, and as an object of the understanding, according to the Zohar, he is nothing, the mystery of mysteries; but he took form as he called forth them all. The ancient of ancients is now seen in his own light; that light is his holy name, the totality of the Sephiroth. The order of their emanation is as follows: From Kether, the Crown, the primal emanation of En Soph, proceed two other Sephiroth–Chocma (wisdom), active and masculine; the other Binah (understanding), passive and feminine, the combination of which results in thought, of which the universe is the effect. The crowned Memro, or Kether, or primordial Logos, is the thinking power in creation, Chocma the act of thinking, and Binah the subject of the thinking.” - Zohar

Illustration of the “Russell-Rodin” reduced-doubling-circuit numbers.
Note how the vertically-opposing (male-female) numbers all add up to 9 (the whole): 9, 8+1, 7+2, 6+3, 5+4.
The red-opposing (Russell) numbers always add up to 0 (which is the fulcrum of balance of the 9): 1 -1, 2 -2, 3 -3, 4 -4.
The 4 -4 position is the maximum distance of the polarity tension and
simulates rest in the physical universe, but this position is not rest! The 4 -4 positions are also not located on the 0 point, as it may seem from this simple 2D illustration.
Out of stillness comes seeming motion:
Seeming motion (9) arrises from the polarization of stillness (0) into 7 distinct octave notes:
the maximum pressure note between the male and female side corresponding to the ±4
1, 2, 4 corresponding to +1 +2 +3 represent the male polarity charging side
8, 7, 5 corresponding to -3 -2 -1 represent the female polarity discharging side

Raj Lok symbol
“Jain cosmology considers the universe, as an uncreated entity, existing since infinity, having neither beginning nor end. Jain texts describe the shape of the universe as similar to a man standing with legs apart and arm resting on his waist. This Universe, according to Jainism, is broad at the top, narrow at the middle and once again becomes broad at the bottom.”
note: how this slight asymmetry might indicate the male-female
polarity. -

Jain time cycle
“According to Jain cosmology,
the universe does not have a temporal beginning or end. Its “Universal History”
divides the cycle of time into two halves (avasarpiṇī and utsarpiṇī)
with six aras (spokes) in each half, and the cycles keep repeating perpetually. Twenty-four Tirthankaras appear in every ara, the first Tirthankara founding Jainism each time. In the present time cycle,
Rishabhanatha is credited as being the first tīrthaṅkara, born at the end of the third ara ” -

Sri Yantras are a type of sacred geometry symbolism from
ancient India.
“Most yantras include
triangles. Downward pointing triangles represent
feminine aspect of God or
Shakti, upward pointing triangles represent
masculine aspect such as
Shiva.” - wikipedia
note: the cube and circle shapes (the polarity of spiritual-physical, silence-rest, formless-form and stillness-motion), the 8 polarized
triangles representing the
2 sets of 4 motion states plus one inner triangle representing the
undivided (non-dual) whole of the
9, the 4 openings (vertical and horizontal connection to the outside).

“64 codons, 61 represent amino acids, and the remaining three represent stop signals, which trigger the end of protein synthesis. Because there are only 20 different amino acids but 64 possible codons, most amino acids are indicated by more than one codon. (Note, however, that each codon represents only one amino acid or stop codon.) This phenomenon is known as redundancy or degeneracy” -
