Did you know?
I first encountered this term in the world of Harry Potter—it was Hermione Granger’s favorite subject. Although neither the books nor the movies go into much detail, one thing they do highlight: it’s all about the magical power of numbers.
The esoteric science of numbers—which has been called numerology since the 20th century.
With the help of numerology, Hermione learns to see more, do supernatural things, predict the future… and perform magic.
And what about you? 🙂
Do you keep seeing the same number on the clock every time you glance at it? Do several people close to you share the same birthday, though in different months? Or perhaps your lucky number keeps appearing in unexpected places?
All of this happens for a reason—numbers are the building blocks of the world around us.
In the following, you will learn:
Even if you hated math… you will love this field!
Everything about numerology—in one place.
From Numerology to Arithmancy
Numerology is sometimes referred to as arithmetic—and before the 20th century, it was called arithmancy. In many languages, it is called arithmancy, a term of ancient Greek origin composed of two words:
Thus, “arithmancy” in ancient times was divination through numbers, where numerical values were assigned to letters.
This ancient practice traces its roots back to ancient Greece, where the first documented work on the subject originates.
The origin of arithmetic itself, however, goes back even further: an Assyrian inscription from the 8th century BC, commissioned by Sargon II, states that “the king built a wall in Khorsabad 16,283 cubits long to match the numerical value of his name.”
The repetition of numbers and synchronicity were observed thousands of years ago: Chaldean numerology is based on ancient Babylonian practices, and Jewish Kabbalistic studies examine the recurring numbers in the Old Testament. Moreover, many occultists believe that the appearance of 11:11 is connected to the Tetragrammaton—the unpronounceable four-letter name of God in Israel.
Numerology, therefore, is thousands of years old: it dates back to ancient Egypt, Sumer, and India.
Different languages, cultures, empires, and people—yet numbers were universally used to describe the divine forces found in nature.
Coincidence?
There are four types of numerology, each with different methods and belief systems:
Chaldean Numerology: This system is built around the numbers 1-8, excluding the number 9 due to its sacred significance. Single-digit numbers represent a person’s external personality, while double-digit numbers signify their inner self.
Kabbalah Numerology: This system uses the numbers 1-9 to assign numerical values to each letter of a person’s name. By analyzing the vibrational frequencies of the resulting numbers, it seeks to understand the past and present to help predict the future.
Tamil Numerology: This system uses three numbers to describe a person’s essence: their birth date, the full birth date including the year, and the numerical value of their name. The resulting numbers provide insights into the person’s traits and future development.
Pythagorean Numerology: Known as modern numerology—or Western numerology—this is the most commonly used system. It involves single-digit numbers 1-9, along with the master numbers 11, 22, and 33.
The most commonly used form of numerology today is based on the teachings of the ancient Greek philosopher and mathematician Pythagoras (around 2500 BC).
Yes, he’s the same wise man who invented the Pythagorean theorem (which you probably remember from math class)
Pythagoras was a brilliant mathematician—but he wasn’t only interested in quantitative solutions. He believed that the physical world is a sum of the energetic vibrations of numbers. He taught his followers (the Pythagoreans) that everything vibrates according to its own number, and even the planets resonate according to their specific frequencies.
From these ideas, he developed a system where letters were matched with numbers.
This discovery led the Pythagoreans to the conclusion that “everything is number.”
Most modern numerologists consider the ancient Greek Pythagoras to be the father of numerology.
One interpretation of “everything is number” is that people can measure everything in the world and then describe it using numbers and ratios—a reasonable idea that has greatly influenced science and mathematics.
However, another interpretation suggests that everything in the world is made up of numbers and can be reduced to numerical values—perhaps even the afterlife
Today, unlike the Pythagoreans, modern numerologists apply numbers to people, while also assigning intangible concepts to numbers—foods, objects, and colors all vibrate.
As a result, for people to live productive and harmonious lives, they must ensure that their environment resonates with their own vibrations.
This brings us to the realm of spiritual teachings.
The numbers in numerology form a vast, powerful, and sacred system.
It’s no surprise that:
… and it’s also no surprise that it influences culture, science, religion—and, most importantly for us, astrology and tarot!
Fun Fact!
This is why the Celestial Spirit Journey is built on three main pillars:
— Tarot,
— Astrology,
— Numerology.
Because, just like with the other two, the key word in numerology is:
Self-discovery.
Numerology—alongside astrology and tarot—not only answers the external question of “How do you express yourself?” but also delves into the internal question, “What energies are stirring within you?”
I personally use it extensively to add more dimensions, further nuances, and extra knowledge to my work: it incredibly enriches mystical teachings.
For example, it’s a great companion to astrology: it helps to better define and complement the characteristics of a sign, planet, or house. If you were born under the sign of Cancer (astrology) and your Life Path Number is 6 (numerology), then…
In numerology, the Life Path Number is similar to your sun sign in astrology: it reveals your identity, including your strengths, weaknesses, opportunities, threats, motivations, and ambitions. Your Life Path Number also sheds light on the nature of your experiences and why events have happened in the past, are happening in the present, or will happen in the future.
Therefore, numerology provides insights into personality, future events, and even the meaning of life.
It can be used for:
… and, through these, for gaining a deeper understanding of yourself.
But how?
Numerology deals with the symbolic meanings and properties associated with numbers, which stem from their inherent vibrations.
In numerology, the digit zero (0), the single digits from one to nine (1-9), and the first three repeating numbers (11, 22, and 33) possess special mystical qualities.
All the phenomena in the world can be understood through 9 basic numbers and 3 master numbers—each number provides guidance and insight into understanding the deeper meanings of life.
In almost all calculations done in numerology, numbers are reduced to a single digit.
In numerology, any number can be simplified or reduced to a single digit—and although there are exceptions (such as master numbers or angel numbers), we almost always continue reducing until we arrive at one of these single-digit numbers.
To do this, you’ll need to add the individual digits together.
For example, with birth months, the first nine months remain unchanged, and the double-digit months are:
Here’s some good news: you don’t need to be a mathematician to discover the magic of numerology. All you need is a pen, paper, and a few super simple arithmetic tasks (or the nearest calculator) to begin exploring the mystical properties of numbers.
The basics of understanding and using numerology begin with the comprehension of the 10 core numbers that form all infinite numbers: the zero and the numbers 1 through 9.
These are the digits that constitute all other numbers—master numbers, angel numbers, special numbers, and even the five most important numbers in numerology, the personal numbers.
These include:
You can find more information about the meanings of these numbers on the “Number Meanings” page in the numerology section of Celestial Spirit Journey.
Keywords: new beginnings, new opportunities, infinity.
Zero represents pure, perfect consciousness that has not yet manifested.
Keywords: new beginnings, new inspirations, initiation, independence, masculinity.
Just as Aries, the first sign of the zodiac, is about action and initiation, the number 1 in numerology is associated with progress.
In numerology, the number 1 symbolizes new beginnings, potential, and creative independence—it represents novelty, movement, and the opportunities that lie ahead. In spiritual symbolism, it is the number of creation and the birth of all things—the divine origin of the universe.
The number 1 symbolizes pioneering spirit, independent nature, and innate leadership abilities.
Those associated with the number 1 are often leaders and trailblazers who create their own paths. They are characterized by heightened motivation and drive—they are true pioneers eager to forge new endeavors and pave the way for others. They are natural leaders and proactive forces. People whose Life Path or Destiny Number is 1 tend to become leaders rather than followers.
The number 1 in numerology carries traces of masculine energy and confidence, which encourage progress in life. Through independent and decisive action, along with embracing their unique qualities, they can develop strong self-confidence.
The greatest strength of the number 1 in numerology is its independence, as this leads to new opportunities and growth potential.
On a bad day, the number 1 can be somewhat bossy or boastful, hiding insecurities behind an overly developed ego. It’s important to remember that while 1 may be first, it can quickly become the loneliest number. Even the most autonomous 1s need the support of friends, family, and loved ones. However, the greatest weakness of the number 1 is the lack of foresight and exploration in life.
Keywords: balance, relationships, social connections, femininity.
The number 2 is associated with sensitivity, balance, and harmony—bringing with it equilibrium, stability, and strong emotional connections.
In numerology, the vibration of 2 plays the role of a mediator, creating harmony by bringing together dissonant forces through compassion, empathy, and kindness: it is about social aspects, complementing and supporting others, nurturing, cooperation, striving for balance and peace, and avoiding conflict.
Therefore, 2 is connected to psychic abilities and intuition, and when this number appears as a Life Path or Destiny Number, it indicates someone who is keenly aware of subtle energy shifts and emotional nuances.
The number 2 represents highly intuitive types who are effective bridge-builders. They typically have a talent for reading people and knowing how to reach out to others. They may have insights and revelations about life that they can share to inspire others.
The number 2 in numerology is a feminine number, carrying nurturing energy that helps uplift and bring others together.
Its greatest strength is the caring spirit that resonates through the number 2, encouraging people to take care of others.
However, it’s important for those influenced by the number 2 to learn boundaries and how to say no. The greatest weakness of the number 2 is the fear of disrupting harmony, which can hold them back from taking action in their lives. Because 2 is so sensitive, it can be very conflict-averse and may end up feeling undervalued or unrecognized. Those with this number need to avoid seeking external validation and instead recognize that the perfect balance they seek already exists within.
Keywords: love, creation, expression.
The number 3 in numerology symbolizes creativity, passion, and social connections. Symbolically, the number 3 represents the outcome of two united forces—the essence of creation.
In astrology, the third house is associated with communication, and in numerology, the number 3 is closely related to this area as well.
The number 3 is highly talented in expression, effortlessly sharing its innovative and pioneering concepts through art, writing, and speech… and even bringing about healing through writing and public speaking. Thus, the number 3 represents all forms of creative expression, and many who resonate with this number are naturally gifted—this number adds charm and kindness to their personality.
Their work inspires, motivates, and uplifts others, and 3s take great joy in bringing smiles to others.
In numerology, the number 3 suggests masculine energy and passionate drive, encouraging people to embrace the past, present, and future.
One of their greatest strengths is their optimism, which encourages people to embrace life with open arms.
However, the main weakness of the number 3 in numerology is a lack of depth, as it avoids exploring negative emotions—leading 3s to be somewhat whimsical, and if they feel misunderstood, they may withdraw entirely. Their tendencies to escape can be mitigated by practicing peaceful mindfulness: with such an active imagination, it’s important for 3s to find calm moments to recharge, recover, and restart. Thus, 3s need to learn to express themselves openly and honestly, rather than suppressing uncomfortable emotions.
Keywords: stability, foundation, manifestation, boundaries, orderliness, objectivity, security.
In numerology, the number 4 represents resilience, practicality, and commitment—its energy is earthy, focusing on strengthening roots.
4 firmly believe in the physical world and understand that investing in a solid infrastructure is necessary for building a lasting legacy.
Are you pragmatic, sensible, and organized? Then 4 might be your natural ability number. This number is associated with practical builders—those who put things together and get things done. Practical, diligent, and responsible, the vibration of the number 4 focuses on creating logical systems that support scalable growth: they are the logistical problem-solvers with analytical minds geared toward strategy and planning.
The number 4 in numerology carries feminine energy, radiating stability and promoting efficiency. The primary strength of the number 4 is reliability, which inspires trust—additionally, they will feel extremely liberated and inspired when they find the courage to take some bold risks.
However, 4s possess a solidity that can quickly turn into rigidity—their greatest weakness is inflexibility, which deters and prevents new experiences and opportunities. They can easily become stubborn, so it’s beneficial for 4s to learn how to relax and think outside the box: they must remember that rules are meant to enhance, not hinder.
It’s also important that they avoid overworking, stressing, or sweeping their emotions under the rug.
Keywords: conflict, test, self-reflection, change.
The number 5 in numerology signifies autonomy, flexibility, and change—it is the most free-spirited of all numbers. Free-thinking, adventurous, and progressive, it is defined by freedom.
The need for change, to shake things up—challenging stability so as not to get stuck. The number 5 in numerology radiates masculine energy that fosters socialization and adventure.
For this reason, 5s need to experience the world through all five senses: they gain life lessons through acts of spontaneous courage. They love to travel and are typically restless. If you are adventurous, spontaneous, and a risk-taker (think fire sign energy), you might be a 5. Similar to Sagittarius energy in astrology, the number 5 is known for its playful, impulsive, and lively spirit.
One of the greatest strengths of the number 5 is its positive energy, which encourages others to take life lightly. 5s are strong communicators who typically excel in sales, marketing, branding, or anything within the communication industry.
However, on the flip side of their zest for life, 5s can become restless and impatient. The greatest weakness of the number 5 lies in reckless and unpredictable behavior: they encourage change and flexibility without necessarily supporting well-thought-out plans. They also worry about feeling trapped, which can complicate relationships and lead to high turnover in their careers. They need to take enough risks and find excitement in what they do to avoid blaming others for feeling confined.
Because 5s are always seeking exploration, they find it challenging to accept the everyday obligations of life—including professional and interpersonal commitments. 5s must remember that if they narrow their focus, they will discover that the most rewarding exploration exists in their own backyard.
Keywords: harmony, growth, decision.
In numerology, the number 6 represents empathy, protection, and compassion. Overflowing love, support, and care—this is the essence of the number 6.
This number carries primarily feminine energy and possesses a nurturing spirit: its main strength is the ability to offer unconditional love. With its deeply compassionate nature, the number 6 exudes positive energy towards everyone it encounters.
Like the sixth house in astrology, ruled by the service-oriented and highly communicative Virgo, the number 6 is often found in the charts of both artists and service workers. Artistic types tend to work in design, beauty, fine arts, aesthetics, music, and similar fields—while service-oriented types are active in therapeutic industries, the social sector, healing segments, and community outreach, enriching the lives of others.
The number 6 suggests an extremely empathetic nature, a true healer who can solve problems on both emotional and physical levels, helping others with a straightforward yet gentle approach. They have a strong sense of responsibility and deeply care for their friends, family, and loved ones—able to give deep and committed love, offering unconditional love to their partner and family. This number also communicates easily with children and animals, showing a gentle and caring spirit.
However, not everything and everyone needs to be cared for, nurtured, or supported, so sometimes the protective energy of the number 6 can become overbearing and controlling. To avoid carrying the weight of the world on their shoulders, 6s need to learn to develop trust and understanding towards others—simply put, everyone must follow their unique path. Yet, the greatest weakness of the number 6 is that it seeks love and respect so strongly that it prevents those associated with it from expressing their true selves. As a result, those with the number 6 may struggle with self-acceptance and find it difficult to receive love from others. They may also be overly critical of themselves, which can sometimes affect others.
They must learn to love themselves as much as they love others and understand that they are enough just as they are.
Keywords: spirituality, knowledge, questioning.
Objective observation, analysis, thirst for knowledge, thoughtfulness, emphasis on internal thoughts, purification of habits for growth. The number 7 in numerology represents a deep spiritual connection with the Universe and logical thinking.
The number 7 rules knowledge and truth—its greatest strength is intellect and a thirst for knowledge.
The number 7 in numerology carries masculine energy that encourages introspection.
Astrologically, the number 7 can be viewed as a blend of Virgo and Scorpio energy: 7s are highly detail-oriented, but instead of being guided by tangible reality, they are led by inner wisdom.
This is a mysterious number that fosters and awakens deep curiosity. They are the detectives of numerology, known for their investigative skills and analytical abilities: they have a sharp eye, and even sharper observations fuel a quick-witted, resourceful spirit.
When this number appears in daily life, the individual’s natural intelligence supports specialization in a field or becoming an expert in what they do. It embodies the brilliant “geek” mind, highly skilled in research. People associated with the number 7 enjoy learning about both the physical and spiritual worlds—they are teachers, educators, counselors, and decision-makers.
Because they quickly find flaws in almost any system, 7s can be somewhat perfectionistic. Yet, the true weakness of the number 7 is skepticism. People with the number 7 in numerology may be unsure of the world and may let their uncertainty disrupt their ability to trust. 7s often assume there is something wrong, so it’s essential to balance this inherent skepticism with an open mind: they must be careful not to let this number lead them to cynicism or disenchantment; instead, they should tap into the spiritual blessing associated with it, as the number 7 in numerology can guide and lead in the search for spiritual understanding.
Many 7s find it difficult to trust others, often due to betrayal in their past. They must develop their inner connection through meditation, yoga, or introspection—and it would be wise to allow people to gradually earn their trust.
Keywords: action, manifestation, abundance.
Determination, ambition, vision, generosity, foresight, focus on achieving dreams.
The number 8 is all about abundance: it symbolizes ambition, drive, and the desire to succeed in the material realm. In numerology, this number is connected to financial prosperity and success.
Those who resonate with this number seem to attract both positions of power and higher salaries. They have a natural business acumen and are natural managers or leaders. Many of them have a “love-hate” relationship with money and power. The ambitious and determined 8s can easily find themselves in leadership roles thanks to their natural charisma. The number 8 uses big-picture thinking to expand its reach and soar to extraordinary heights at the top of any ladder.
Their path is about tapping into what truly motivates them and achieving inner self-worth. However, it’s important that they do this not for status, but for the enjoyment.
With great power comes great responsibility: 8s can become workaholics, and on bad days, overly controlling and possessive. The primary weakness of the number 8 in numerology is arrogance—these individuals believe that their flexibility and reliability entitle them to more respect and recognition.
However, their negative traits can be reduced by giving back to the community. By using success to help others, 8s will realize that nothing is more valuable than contributing to the greater good. It’s no surprise that the number 8 in numerology signifies reliability and resilience—it carries feminine energy that promotes stability and support. The greatest strength of the number 8 is its infinite reliability: supporting others comes naturally to them.
Keywords: contentment, allowance.
In numerology, the number 9 is a masculine number that evokes a sense of inner wisdom, encouraging spiritual growth: serving others, withdrawal, evaluation of the past, fulfillment.
As the final digit in numerology, 9 signifies an old soul—it is no stranger to the highs and lows of life. Since the number 9, in many ways, transcends the physical plane, it must constantly remember to:
On the one hand, the number 9, as the last digit among the core numbers (and single digits), symbolizes completion: the closing of a chapter in life and spiritual enlightenment. It is not afraid of transformation, and its fluid spirit inspires others to explore their own possibilities. Accordingly, 9 can easily synthesize large amounts of information, psychically connecting the dots to create a coherent whole. The path of 9 is thus one of wisdom, understanding, and compassion—they hear the call to turn towards society and make a difference. They are the humanitarians and social conscience bearers, often engaging with or working alongside the public or the masses.
The primary strength of the number 9 is spiritual strength. Those with the qualities of the number 9 in numerology are sensitive to their own and others’ spiritual needs, which helps them grow and understand themselves. The number 9 uncovers hidden aspects of personal development and spiritual journeys.
The mission of 9 is to reach the highest state of consciousness and help others achieve this spiritual awareness as well.
Therefore, 9 must be careful not to let needy people—or energy vampires, if you will—drain them and should practice healthy boundaries. One of their major tasks is to let go of certain attachments in life to stay on the path of leading humanity. In other words, they must learn to follow the path life gives them.
Thus, the greatest weakness of the number 9 is bitterness towards other ideas and beliefs. 9 may resent the notion that there are paths to spiritual enlightenment outside the one they have chosen.
There are a few double-digit numbers that numerologists do not reduce to a single digit.
These are called Master Numbers.
Master Numbers are considered to be an amplified, more powerful version of the core numbers, a kind of higher vibration that transcends the individual/ego—no wonder they are regarded as the most powerful number combinations in numerology. They represent exceptional spiritual strength and knowledge—qualities that other numbers do not possess.
These special numbers hold great promise, yet they can challenge those who carry them in their “numerological horoscope.” Master Numbers suggest a powerful vibrational energy related to learning, achievement, and success, but they are likely to manifest in more stressful or higher-stakes environments.
For example, Sir Paul McCartney, perhaps England’s most famous Gemini sun sign, was born on June 18, 1942. If we reduce this date (month = 6, day = 9, year = 7), the result is 22. Instead of simplifying this to a single digit (which would result in 4), the number 22 remains a Master Number—a higher iteration of 4, reflecting McCartney’s strong “life mission.”
Due to the doubling effect, Master Numbers carry great intensity and push individuals to rise to the potential inherent in the number.
Master Numbers consist of the double-digit numbers 11, 22, and 33.
For more detailed meanings of these numbers, you can visit the “Number Meanings” page in the numerology section of Celestial Spirit Journey.
In numerology, the Master Number 11 is associated with spiritual enlightenment, awareness, and philosophical balance—suggesting strong intuition and spiritual knowledge.
The number 11 would reduce to the root number 2, which is why it not only shares similar qualities in terms of balance and offering support to others but also amplifies the energy of the number 2: its purpose is to heal itself and others through heightened psychic abilities.
It is often the case that the intuitive gifts of the Master Number 11 arise from extreme life circumstances: they have no choice but to cultivate their extrasensory talents.
One of the strengths of the Master Number 11 is empathy. Those aligned with the number 11 possess an innate understanding of others’ emotional needs.
However, its greatest weakness is a tendency towards inner conflict. Due to the powerful intuitive energy of the number 11, it can disrupt their desire to promote harmony and balance.
The number 22 is perhaps the most powerful number in all of numerology. It is one of the Master Numbers believed to turn dreams into reality, no matter how impossible those dreams may seem—it symbolizes ambition and idealistic dreams.
The number 22 is often called the Master Builder because it radiates positive energy that welcomes growth and development.
It inspires the creation of opportunities, platforms, and things in the physical world that go beyond immediate reality—by uniting the tangible and the intangible, the Master Number 22 creates a dynamic, long-lasting legacy.
In numerology, the Master Number 22 would reduce to the root number 4, expanding the vibrations of the number 4: both numbers demonstrate strong endurance. Therefore, it’s no surprise that its primary strength is dynamic growth and success: it encourages the practical application of idealistic pursuits.
The main weakness of this Master Number is setting unrealistic goals. Those aligned with the number 22 set high aspirations and may feel disappointed if they don’t achieve them.
The abilities of the Master Number 22 often stem from early childhood instability, which fuels innovative thinking. Diligent, creative, and reliable, they are always on a mission of transformation. If you carry a Master Number yourself, it’s essential to work constructively with your abilities and talents while learning how to manage the challenges that come with this powerful influence.
The number 33 would reduce to the root number 6, which radiates love and compassion: it possesses powerful spiritual energy that exudes empathy and mutual respect.
Its primary strength is empathy. People with the numerological number 33 have a deep understanding of human emotions, and this is reflected in their actions towards others.
The greatest weakness of the Master Number 33 is assertiveness—while this number suggests unparalleled empathy for others, sometimes these individuals can be insistent that their methods are superior.
When you see repeating numbers like 111, 1221, or 21:21 as mentioned in the introduction, it’s not just a coincidence—it’s synchronicity. Synchronicity is much more than mere chance; it’s the experience of two or more seemingly unrelated events occurring together in a way that has deeper meaning.
It’s proof that everything is part of a unified, interconnected whole—everything is one, and one is everything.
In numerology, angel numbers are sequences of numbers (usually three or four digits) that contain repetition (like 111 or 4444) and/or patterns (like 1234 or 23:23).
These numbers are believed to be messages from the spiritual Universe, offering insights, wisdom, and guidance—they could be direct messages from angels, the Universe, your spiritual guides, ancestors, spirits, or even a higher state of your own consciousness.
As such, they carry a powerful message that the Universe feels YOU need to hear.
Since your guardian angels are always watching over you, they will continue to show you these numbers until the lesson reaches you. Think of these numbers as if your spirit guardians are jumping up and down, waving at you, trying to catch your attention. The longer you go without noticing these angel numbers, the more frequently you are likely to see them.
Examples include:
But they can also appear as patterns on the clock:
You can find more information about the meanings of these numbers on the “Number Meanings” page in the numerology section of Celestial Spirit Journey.
While not strictly part of numerology, there are numbers that hold special significance in people’s lives.
This belief often assigns numerology-like qualities to these numbers when they appear.
This concept has led to the mystery of the number 23, the number of the beast 666, or the unlucky number 13—along with other beliefs suggesting that certain numbers are at the center of a pattern or conspiracy.
Examples include:
You can find more information about the meanings of these numbers on the “Number Meanings” page in the numerology section of Celestial Spirit Journey.
With a “numerological horoscope analysis,” a person’s Destiny Number, Birth Number, or Life Path Number can be determined.
These are called personal numbers because they are calculated based on individual traits (e.g., birth date, name, etc.), giving them qualities specific to the person.
In numerology, the 5 most important personal numbers are:
