Yi Jing, Oracle of the Moon

1
The number of primordial being.
The All, the absolute. It is always the same and unchangeable. It contains all other numbers, but cannot be multiplied. It is nonpolarized, both male and female - or no gender at all.
Without duality there is no doubt, no insecurity, no fear. An Ace is the first start to a goal, the vision or ideal.
An Ace is abstract, it is up to you to act on it, to take the first step.
There's so much motivation and momentum surrounding this single-digit number. It is a true pioneer, eager to break ground on new endeavors and pave the way for others to follow. It is a natural leader and a proactive force. The number 1 represents newness, movement, and the possibilities that await us. In spiritual symbolism, it is the number of creation and the birth of all things -- the divine origin of the universe.
In Numerology the number 1 is the root of opportunity in our lives. It is a symbol of confidence, power, and action. It pushes us to look at our current circumstances and realize that we have the power to turn them into anything we wish. Even if we are afraid, the 1 inspires us to take control of our future and embrace new beginnings.

Ace of Cups (yin water): unconditional love.
Ace of Pentacles (yin earth): planting a seed.
Polarity and division
Duality, the beginning and foundation of reality and division, of matter, time and space. Contrast, opposition, but also balance.
The Numerology number 2 is known to numerologists as a supremely feminine force, one that represents both grace and power. It is cooperative, always aiming to bring peace and balance back to a relationship or situation. This Numerology number is also very sensitive - of all the numbers, it has the strongest intuition. It is able to sense currents and feelings instinctively, then use these clues to connect with others empathically.
At its very core the 2 in Numerology represents partnerships -- the coming together or balancing of two individual people, concepts, or things. While it holds great power over any situation, it wields it with such diplomacy and tact that the result is not control and authority, but harmony and teamwork. It is a mediator, able to see two sides of a situation in an unbiased way and guide others down the middle road.
2 of Wands: time, the split-second creative act, social life.

The embracing synthesis.
Overcoming the division by integrating both. Spiritual love. Trinity and three-dimensionality is the building principle of the universe we know, creation. Two creates the world's reality in duality, three creates life. It is the number of the woman. There is Reason-Perception-Wisdom but also Reason-Perception-Will. Or Come up-Exist-Descend. When we hear a rumor 3 times, we accept it as true.
The 3 has a tendency to thrive in an upbeat and engaging atmosphere. Its energy is youthful and positive and it has an incredible zest for life. It dances from one enjoyable experience to the next, eager to interact with others along the way. The prized skill of the number 3 is communication and it uses this talent to build a wide and interesting circle of friends, lovers, and kindred spirits.
The 3 is highly original and embraces unique thinking and creative expression. This number's artistic, curious nature allows it to convey abstract ideas and find solutions others may miss. A child at heart, the number 3 never misses a chance to have fun, engage with others, and express all the love and joy it embodies.

3 of Pentacles/coins: The Three is traditionally the card of genius. Here we usually see a master craftsman conferring with his masons on the installation of a beautiful stained-glass window in the cathedral. This designer is often likened to Leonardo da Vinci or Michelangelo, a multi-talented visionary who has no peers in talent or productivity.

Material order
The compass, the 4 elements, 4 phases of the moon, a cross, the Egyptian hieroglyph for immortality, Shiva, the 4-armed god. A Mandala gives rest and a home to the wandering spirit. The feeling of safety from knowing where you are.
A wise and rational energy that can bring us a sense of security and consistency. It has a strict definition of right and wrong and tends to see things as black and white with no grey in between. The number 4 leads with its head, not its heart, and uses this mental strength to build a life of service and contentment.
When strength and efficiency are needed, it's number 4 to the rescue. It is a no-nonsense number with a heads-down approach to life and work. It is extremely dependable and lends a great amount of stability to a person or situation. The 4 is dedicated to advancing, but in a more conservative way. It sticks to what is tried-and-true instead of attempting methods that are new.
The number 4 creates a very stable, grounded vibration, a great day to stay focused on the tasks at hand and get things done. When you tap into the energy of this ‘4’ day, you might be surprised at how much you accomplish. If you’ve been putting off starting a new project, today is a good day to revisit the project and make a plan of action. When you invest time in building a sturdy foundation and making structured plans, all of your projects (whether personal or professional) will flourish.
Be mindful of your interactions with others today and don’t let yourself get carried off track by other people’s ideas. When you stay focused on what matters, you’ll find that it can be a fun, and maybe even profitable, day. (numerology.com)

The number of life and love
Quintessentia.
The number of man, 2 + 3, a mixture of even and odd, of good and bad, of light and dark, male and female. The 5 senses. It is absent from crystals but a typical structuring number in living nature. It is an unruly number, not able (or refusing) to create a 'perfect' structure. The journey of the planet Venus is a pentagram, the 'lover's knot', symbolizing endless love and the rule of the spirits over the elements. In China life is pervaded by 5, in the West the 5th element is the invisible/spiritual one, ether or the quinta essentia. A pentagram is the sign of Ishtar and lends protection as an amulet. It is also a sign of the microcosmos.
In the span of single-digit numbers 1-9, 5 is the number in the exact middle. It acts as a go-between and a pivotal point of change.
5 of Wands: initiative, ambition, competition, drive and desire.
5 of Swords: cleaning up the battlefield.5 Life and love
5 of Cups: inheritance.
5 of Pentacles: 
Perfection of creation. 1+2+3 or 1x2x3.
The number 6 is the embodiment of the heart. It represents unconditional love and the ability to support, nurture, and heal. It is a powerful force of compassion and empathy and its warm light is a beacon of hope. Its role is to use its heart and soul to be of service to others.
The 6 in Numerology shines in partnerships of all kinds but especially emotional ones. Its empathy makes others comfortable letting down their guard and being open and honest about their feelings which, in turn, allows it to understand and provide the help that's needed. We could all use someone in our life who manifests the devoted energy of the 6.

The pillars of wisdom
The number 7 is both deep and wise. It is not satisfied with simple explanations and surface-level information -- this is frivolous stuff. It knows that the real gold is buried deeper and won't stop until it finds it ... and then it'll keep digging for more. Asking questions, researching, listening, and sensing are all special skills the 7 uses in its search for awareness.
Though spirituality is especially important to the number 7 in Numerology, it takes a more intellectual approach to life than an emotional one. It is an analytical number that enjoys gathering and filtering through information to find answers. Still, it has a more powerful intuition than you might expect which it uses as a guide. This combination of conscious and subconscious thinking allows the mind of the Numerology number 7 to shine a light into the very deepest realms to access hidden truths.

Of all the numbers in Numerology, the number 8 is the achiever and measures life by the goals it reaches. It has good business sense, a powerful presence, and a strong drive for success. The 8 is also a symbol of balance -- you can see it in its symmetrical shape. For every blessing it receives, it puts one back out to the universe. When things are balanced, they feel stable, controlled, and supported, which is the most productive environment for the 8 to work in.
In Chinese culture, the number 8 is considered the luckiest number of all, and is purposefully worked into wedding dates, birth dates, addresses, and finances. Even in the world of Numerology, there are people who have been known to change their name in order to add more 8s to their Numerology chart, hoping to emulate this number's level of accomplishment. The 8 represents an ultimate form of achievement that many will spend their entire lives striving for.

The energy of the number 9 represents completion, but not finality. Think of it more in a cyclical sense; it's about the ending of one cycle and the potential it creates for another cycle to begin. The 9 in Numerology acts as an usher in this process of transition or transformation, guiding and empowering us with its wisdom. It absorbs answers from a spiritual source, then delivers them to us in the real world.
This number is a humanitarian at heart. It is compassionate, kind, and intent on putting its efforts toward creating the greatest good. The 9 in Numerology has gone through its fair share of hardship and is wiser, stronger, and more aware as a result. These first-hand experiences make it especially understanding of others who are struggling and willing to provide valuable support.
