In Chaldean numerology, numbers are primarily associated with the following planets: 1 and 4 are linked to the Sun, 2 and 7 to the Moon, 3 with Jupiter, 5 with Mercury, 6 with Venus, 8 with Saturn, and 9 with Mars. Additionally, the number 4 is associated with Uranus and the North Lunar Node or Dragon’s Head (Caput Draconis), while the number 7 is linked to Neptune and the South Lunar Node or Dragon’s Tail (Cauda Draconis). Some also connect the number 0 with Pluto.
The Birth Number and the Total Name Number (TNN) are typically among the strongest activators of planets. For instance, if someone is born on the 6th of the month, their Venus, tied to the number 6, will be activated more strongly. If a person has a TNN of 73, their base number becomes 1, which is associated with the Sun.
Once we identify the key planets based on these numbers, we can analyze the astrological chart in both tropical and sidereal systems. Sidereal positions tend to have more power, on average. We can examine planets in their signs, houses, and aspects.
If, for the aforementioned individual with a TNN of 73, the Sun is located in Aquarius, this indicates a state of exile in astrological terms. If it is additionally positioned in the 12th house, which brings challenges, and in opposition or square aspects with other planets, it suggests that through numerology the “planet” Sun would be activated in the natal chart, along with all the difficulties this entails. While the number 73 may bring positive influences, actions in the astrological chart could also head in the opposite direction.
Therefore, it is crucial to consider multiple criteria when numerologically changing names and surnames. Since numerologists often lack all the necessary expertise, I recommend taking additional precautions with appropriate methods when altering your name or surname.
