On Sacred Numbers & Geometry
Esoteric wisdom observes that each number correlates to an objective reflection, or manifestation, of a spiritual and cosmic fact. These facts manifest through cycles, cadences, and forms in the physical world. Everything in the physical world is a perfect expression, somehow, of an impulse or rhythm from the universal-cosmic source that created, informs, and sustains the universe.
These principles have come to known in the field of mathematics - which is the only field in the sphere of academics if absolutely objective - as "sacred geometry" or "sacred numbers." These realities manifest in geometric forms and points including the triangle (3 points, the triad, the trinity, etc.), the circle (no points, eternal that which has no beginning and no end), and the square (4 points, the symbol of the physical sphere) - all of which correlate to a fundamental principle of the manifested and unmanifested universe.
The most observable, perhaps, numbers and that we encounter day to day that correlate to cosmic cadences include 1 (monad), 2 (dyad), 3 (triad), 4, 5, 6, 7, 9, and 12. The facts regarding sacred numbers and geometry were taught across the world since time began. They were revealed first to the initiates and teachers in the ancient Mystery Centers and taught to others as fundamental aspects of nature, science, farming, the human being, construction, and the spirit. In recent ancient memory before the great deluge sometime around 9500BC, the ancient Indians, Persians, and Egyptians are remembered as effective use of these principles in architecture, engineering, and culture. The Egyptians are, perhaps, most remembered for their expert use of geometry and mathematics which were utilized to construct the pyramids and the massive and sacred structures that survive today.
Later, this wisdom flowed through the West by way of the Greeks and evolved into our current forms taught today through men such as Pythagoras, Aristotle, and Plato; all of whom were initiates trained in the ancient Mysteries. The Greeks and Romans - as is most visible today through construction principles - brought their innovations to the world. Dr. Steiner revealed that the great initiate Pythagoras was, in fact, trained in the ancient Egyptian and Chaldean mysteries where he spent some 20 years of his life.
Numbers and principles of mathematical laws were never invented by anyone. No one culture can take credit for it. They are only discovered, and rediscovered, by those who are seek the answers. Mathematical laws are correlations to the facts of the human being, the world, and the cosmos. Today we acknowledge these fundamental principles for use in worldly endeavors including medicine, technology, finance, engineering, etc. but the inner meaning behind them is becoming lost.​

The following is a partial list only and is intended only to be a introduction for further research.

On the Number 7
​The number 7 is, perhaps, the most observable manifestation in the physical world. It occurs in many instances. This sacred cadence manifests itself out of the cosmos, or macrocosm, into humanity, and the world, or microcosm.
For example, the number 7 can be seen in:
-7 vowels.
-7 musical notes.
-7 fundamental colors (in the prism and the rainbow).
-7 days of the week.
There are 7 leading Archangels who govern humanity by way of 7 successive cycles during which time they bring unique influences to the world. Dr. Steiner confirmed that these cycles occur on average every 350 (300-400) years with the most recent regency beginning in 1879 with the Archangel Michael.
​
-7 Archangels (Regents or Leaders).
-7 virtues.
-7 deadly sins.
-7 musical notes.​
-There are 7 aspects of the human being when viewed from the lens of Anthroposophy.
-The 7 planetary influences that correspond to 7 days of the week.
-The 7 Rishis of India.
-The 7 degrees, or stages, of spiritual initiation.
-The 7 planetary influences/spheres:​
Saturn: Saturday
Sun: Sunday
Moon: Monday
Mars: Tuesday
Mercury: Wednesday
Jupiter: Thursday
Venus: Friday (1)


On the Number 12
​
The number 12 manifests in a variety of ways including:
​​-The 12 months of the year.
-The 12 constellations.
-The 12 lunar cycles.
-The 12 ribs of the human being.
-The 12 houses of the zodiac. Each "house" of the zodiac requires 2,160 years to complete a cycle. Each of the 12 cycles comprise one cosmic year of 25,920 years.
-The 12-sided (12 pentagonal faces) Dodecahedron (https://en.wikipedia.org/wiki/Platonic_solid)
​
​
​
​
​
​
​
​​​​
Instances of the number 12 can be observed through virtually all religious documents and the mythos of ancient world. For example:
​
-The 12 Apostles.
-12 Years. The number of years that Jesus spent in Egypt before returning to Palestine.
-The 12 Gods of Olympus.
-The 12 Labors of Herakles.
-12 Knights of King Arthur's roundtable.
-The 12 Days of Christmas.
-The 12 Tribes of Israel. Ishmael - the first-born son of Abraham - has 12 sons/princes (Genesis 25:16), and Jacob also has 12 sons, who are the progenitors of the Twelve Tribes of Israel.
-The 12 Gates in the Book of Revelations.​​​​

"These spirits (guiding spirits of humanity) have been acknowledged as regents in symbols, for instance in the zodiac, with the sun moving through them. Enhancement of conscious awareness in microcosmic evolution also corresponds to the stages in the macrocosm. So that the number 12 has always been important and there have always been 12 guiding spirits everywhere: 12 tribes of Israel, 12 apostles, 12 knights of the Grail. Both macrocosmically and microcosmically, 12 is therefore the sacred number on which everything is based.
7 are in action, 5 have other work to do. For the physical planet, only 7 come into consideration, which is also why only 7 of the 12 principles of the human being are taught." -Rudolf Steiner, Part II: 6. Evolution and Involution—GA 89. Awareness - Life - Form (2001)—Rudolf Steiner Archive
