ConceptsSystemsNumbersCalculationsTraditionsSymbols

A

Active Number

Numbers

A number calculated from the first name at birth, reflecting the social personality, the way one acts in the world, and the qualities consciously developed. The active number complements the hereditary number to form a more complete view of numerological identity. It is particularly revealing in daily interactions.

Astrology and Numerology

Traditions

The study of correspondences between numbers and planets, zodiac signs, and astrological houses. Each digit from 1 to 9 is traditionally associated with a planet: 1 with the Sun, 2 with the Moon, 3 with Jupiter, and so on. These parallels allow both disciplines to enrich each other and refine personality analyses and forecasts.

C

Capstone

Numbers

The last letter of the birth first name, revealing how a person completes projects and handles outcomes. It indicates the ability to finalize, to persevere to the end, and to draw lessons from completed experiences. Paired with the cornerstone, it offers a dynamic portrait of the individual's action style.

Chaldean Numerology

Systems

An ancient system originating from Mesopotamia, considered one of the oldest in the world. Unlike the Pythagorean system, the Chaldean table assigns digits 1 through 8 to letters based on their vibrational value rather than alphabetical order, with 9 being considered sacred. This system favors the commonly used name over the birth name.

Chaldean Table

Calculations

An alternative correspondence table to the Pythagorean system, derived from the Babylonian tradition. It uses only digits 1 through 8, with 9 being considered sacred and reserved for divine forces. Assignments are based on the phonetic vibration of letters rather than their alphabetical position, yielding different results from the Pythagorean system.

Challenges

Concepts

Numbers obtained by subtracting elements of the birth date, revealing the difficulties or lessons to overcome during life. There are four challenges corresponding to the four pinnacles. Challenges indicate weaknesses to transform into strengths and recurring obstacles to overcome for personal growth.

Chinese Numerology

Systems

An ancient numerical tradition deeply embedded in Chinese culture, where numbers are classified into yin (even) and yang (odd) categories. The number 8 is considered the luckiest due to its phonetic resemblance to the word for 'prosperity', while 4 is avoided because it sounds like 'death'. This system influences architecture, addresses, and ceremony dates.

Compatibility

Concepts

A comparative study of two individuals' personal numbers to evaluate the harmony of their relationship. Numerological compatibility considers life paths, expression numbers, soul urge numbers, and other indicators. Some combinations are naturally harmonious while others require conscious adjustments.

Cornerstone

Numbers

The first letter of the birth first name, whose numerological value reveals the initial approach to challenges and new situations. It indicates how a person tackles problems, takes initiative, and reacts to change. The cornerstone is one of the most immediate indicators of temperament in letter numerology.

E

Expression Number

Numbers

A number obtained through theosophical reduction of the numerical value of all letters in the full birth name. It reveals natural talents, aptitudes, and an individual's overall potential. The expression number is sometimes called the destiny number and is one of the five core numbers in a numerological chart.

F

Fibonacci Sequence

Symbols

A number sequence where each term is the sum of the two preceding ones (1, 1, 2, 3, 5, 8, 13, 21…), discovered by the Italian mathematician Leonardo Fibonacci in the 13th century. In numerology, this sequence illustrates the principle of organic growth and natural progression. The ratio between two consecutive terms converges to the golden ratio, linking mathematics and symbolism.

G

Gematria

Systems

An interpretive method from the Hebrew tradition that assigns a numerical value to each letter of the Hebrew alphabet. Words sharing the same total numerical value are considered spiritually connected. Gematria is a cornerstone of Kabbalistic exegesis and has deeply influenced Western numerology.

Golden Ratio

Symbols

An irrational mathematical proportion (approximately 1.618) omnipresent in nature, art, and architecture, symbolizing harmony and perfection. In symbolic numerology, the golden ratio illustrates how numerical ratios govern natural beauty and order. It is intimately linked to the Fibonacci sequence and the logarithmic spiral found in seashells and galaxies.

H

Hereditary Number

Numbers

A number obtained by reducing the birth surname, representing family heritage, traits passed down through the lineage, and ancestral influences. This number acts as a foundation upon which other aspects of the numerological personality are built. It reveals strengths and patterns inherited from the family.

I

Inclusion Grid

Concepts

An analytical grid listing the frequency of each digit (1 through 9) in the full birth name. Missing digits reveal karmic lessons, excessive digits signal dominant traits, and average counts indicate natural balance. This tool is also called a birth grid or expression plane.

K

Kabbalistic Numerology

Systems

A numerological system rooted in the Jewish mystical tradition of Kabbalah. It relies on gematria and the study of the 22 Hebrew letters in relation to the 10 sephiroth of the Tree of Life. This approach emphasizes the spiritual and esoteric dimension of numbers rather than personal prediction.

Karma

Concepts

In numerology, karma refers to lessons and debts inherited from past lives or previous actions, encoded in personal numbers. Certain numbers, such as karmic debts (13, 14, 16, 19), signal patterns that need correction. Karma is not a punishment but an invitation to learning and spiritual growth.

Karmic Debt

Concepts

Specific numbers (13, 14, 16, 19) that, when appearing as sub-numbers in a numerological chart, indicate unlearned lessons from past lives. Each karmic debt carries a precise message: 13 concerns work and discipline, 14 freedom and moderation, 16 ego and reconstruction, 19 independence and altruism.

Karmic Number

Numbers

Numbers (13, 14, 16, 19) revealing karmic debts or lessons when they appear in a numerological chart. They indicate areas where particular inner work is needed. Unlike master numbers that amplify potential, karmic numbers signal imbalances to correct for spiritual progression.

L

Life Cycle

Concepts

The division of a lifetime into three major periods called the formative, productive, and harvest cycles, each governed by a number derived from the birth date. The first cycle relates to the birth month, the second to the day, and the third to the year. These cycles define the overarching trends and dominant themes of each life phase.

Life Path

Numbers

The most important number in numerology, obtained through theosophical reduction of the complete birth date. It represents the life mission, fundamental direction, and main lessons an individual is meant to experience. The life path outlines the general trajectory of existence and profoundly influences personality and destiny.

Life Path Calculation

Calculations

The method for calculating the most fundamental number in numerology, involving separately adding the day, month, and year of birth, then reducing each component before adding them together. This intermediate reduction approach preserves master numbers that might be masked by directly adding all digits.

M

Master Number

Numbers

Double-digit numbers with identical digits (11, 22, 33, sometimes 44) that are not reduced during theosophical calculation due to their exceptional vibrational power. They carry high potential but also heightened intensity and challenges. Bearers of master numbers are often called to play an inspiring or transformative role in their surroundings.

N

Numeric Feng Shui

Traditions

The application of traditional Chinese Feng Shui principles to numbers, particularly in choosing addresses, phone numbers, and important dates. Number combinations are analyzed for their influence on the flow of energy (chi) in a space. The number 8 is especially sought for its vibration of prosperity, while 4 is often avoided.

Numeric House

Concepts

The numerical vibration associated with a home or workplace address, obtained through theosophical reduction of the address number. Each number gives the space a particular atmosphere and set of influences. For instance, a house 3 fosters creativity and communication, while a house 4 encourages stability and work.

Numerical Vibration

Concepts

The specific energy or frequency associated with each number in numerology. Each digit from 1 to 9 carries a unique vibration that influences personality, events, and life cycles. This concept is rooted in the Pythagorean idea that the universe is governed by harmonic numerical relationships.

P

Personal Day

Concepts

The finest cycle in predictive numerology, calculated by adding the personal month number to the calendar day. It reveals daily energies and helps choose favorable moments for action. Though subtle, this number can guide everyday micro-decisions.

Personal Month

Concepts

A sub-cycle of the personal year obtained by adding the personal year number to the calendar month number. It refines predictions by identifying trends specific to each month. Personal months provide more precise insight into the timing of events and decisions.

Personal Year

Concepts

A number calculated from the birth day and month added to the current year, indicating the prevailing influences and themes for a given year. Personal years follow a 9-year cycle, with each number bringing its own opportunities and challenges. This calculation is essential in predictive numerology.

Personality Number

Numbers

A number derived from the consonants of the full birth name, representing the outer image projected to the world and the first impression one gives to others. It acts as a filter between the inner self and the outer world. The combination of the soul urge number and the personality number forms the expression number.

Pinnacles

Concepts

Four major life periods, each associated with a specific number derived from the birth date. Pinnacles represent the peaks or major goals one is meant to achieve during each phase. Their duration varies: the first and fourth are the longest, while the two intermediate ones last nine years each.

Predictive Numerology

Concepts

A branch of numerology dedicated to analyzing time cycles and forecasting future trends. It relies on personal year, month, and day calculations, as well as pinnacles and challenges. This approach does not predict specific events but identifies the dominant energetic currents ahead.

Pythagorean Numerology

Systems

The most widely used numerology system in the West, attributed to the Greek philosopher Pythagoras (6th century BCE). It uses a correspondence table where each letter of the alphabet is assigned a digit from 1 to 9 based on its sequential order. This system forms the foundation of most modern life path and expression number calculations.

Pythagorean Table

Calculations

The fundamental correspondence table of the Pythagorean system assigning each letter of the Latin alphabet a digit from 1 to 9 in sequential order: A=1, B=2, C=3… I=9, J=1, etc. This table is the basic tool for converting name letters into numerical values and calculating the various chart numbers.

R

Root Number

Calculations

A single digit (1 through 9) obtained after the complete theosophical reduction of any number. The root number represents the fundamental vibrational essence, stripped of all complexity. Each root number possesses an archetype and specific qualities that form the basis of numerological interpretation.

S

Sacred Geometry

Symbols

The study of geometric forms considered the foundations of the universe's structure, closely linked to numerology. Each number corresponds to a shape: 1 to the point, 2 to the line, 3 to the triangle, 4 to the square, and so on. Sacred geometry reveals how numbers manifest in space and matter, from snowflakes to planetary orbits.

Sephiroth

Traditions

The ten divine emanations of the Tree of Life in the Kabbalistic tradition, numbered from 1 (Kether, the Crown) to 10 (Malkuth, the Kingdom). Each sephira represents an attribute of divine manifestation and an aspect of human consciousness. In numerology, the sephiroth provide a profound interpretive framework for the digits 1 through 10.

Soul Urge Number

Numbers

A number calculated from the vowels in the full birth name, revealing deep motivations, inner desires, and the soul's secret aspirations. This number describes what makes a person resonate at their deepest core, often unknown to those around them. It is also called the heart's desire number or spiritual impulse.

Sub-number

Calculations

A two-digit number obtained before the final step of theosophical reduction, adding an important nuance to the final number. For example, a life path 7 derived from a sub-number 16 differs from a life path 7 from 25 or 34. Karmic sub-numbers (13, 14, 16, 19) carry particularly strong significance.

T

Tantric Numerology

Systems

A numerological system derived from the yogic tradition and Kundalini Yoga, based on the analysis of five key numbers derived from the birth date. These numbers correspond to the soul, karma, divine gift, destiny, and past life. Tantric numerology focuses on spiritual development and the alignment of the ten subtle bodies.

Tarot and Numerology

Traditions

The correspondence between the 22 Major Arcana of the Tarot and numbers in numerology. Each arcanum is numbered and carries symbolism that enriches numerological interpretation. For example, Arcanum I (The Magician) shares the qualities of the number 1: initiative, creation, and new beginnings. This synergy allows for particularly deep cross-readings.

Theosophical Reduction

Concepts

A fundamental mathematical process in numerology that involves adding the digits of a number until a single digit between 1 and 9 is obtained. For example, the number 29 becomes 2 + 9 = 11, then 1 + 1 = 2. Master numbers (11, 22, 33) are exceptions to this rule and are typically not reduced.

Tree of Life

Traditions

A central diagram of Kabbalah composed of ten sephiroth (spheres) connected by 22 paths corresponding to the 22 letters of the Hebrew alphabet. In Kabbalistic numerology, the Tree of Life represents the structure of creation and the different levels of consciousness. Each sephira is associated with a number from 1 to 10, forming a rich symbolic framework.

V

Vesica Piscis

Symbols

A sacred geometric figure formed by the intersection of two circles of equal radius, each passing through the center of the other. In numerology and sacred geometry, the Vesica Piscis symbolizes creative duality (the number 2), birth, and the passage between worlds. It is the matrix of many fundamental geometric forms such as the equilateral triangle.

Y

Yin and Yang

Symbols

A principle of complementary duality from Chinese philosophy, applied in numerology to the classification of even numbers (yin, receptive, feminine) and odd numbers (yang, active, masculine). The balance between these two polarities in a numerological chart indicates the overall harmony of personality. An excess of either polarity may signal an imbalance to correct.
