TL;DR
Your name breaks into three numbers: the Soul Urge from the vowels, the Personality from the consonants, and the Expression from every letter. Use your full birth-certificate name, decide whether each Y is acting as a vowel by saying the name aloud, and always build the Expression from the raw unreduced totals so you never accidentally erase a master number.
The Three Numbers Hidden in Your Name
Your name carries three numbers, and each tells a different truth. The vowels give your Soul Urge, what you quietly want. The consonants give your Personality, how you come across before you say much. Every letter together gives your Expression, the fuller shape of who you are and what you're here to work with.
Below is the table for mapping letters to numbers, the rule for the tricky letter Y, and a worked example you can follow line by line. Most people get one detail wrong near the end, so read to the correction before you trust your own math.
Which name do you use?
Use your full name exactly as it appears on your birth certificate: first, middle, and last. Not a nickname, not a shortened version, not a married name or a chosen name.
The logic behind this is simple: the calculation reads the name you were given at the start, before any editing. It's a snapshot of a beginning, not a record of everything you've become since. Your chosen or married name can be read separately as its own layer, but the birth name stays the baseline in this method.
If your birth certificate lists two middle names, include both. If it lists none, work with what's there.
What is the Pythagorean letter-to-number table?
Every letter maps to a single digit from 1 to 9. Here's the full grid used in the Pythagorean system.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|
| A | B | C | D | E | F | G | H | I |
| J | K | L | M | N | O | P | Q | R |
| S | T | U | V | W | X | Y | Z |
Read it in columns. A, J, and S all equal 1. B, K, and T equal 2, and so on across.
To find a number, add the digits for the letters you need, then reduce the total to a single digit by adding its digits together. The exception is a master number: in the method this tradition teaches, if a total lands on 11, 22, 33, or 44, you hold it rather than reducing it further. We write those in slash form so both layers stay visible: 11/2, 22/4, 33/6, 44/8.
How do you know when Y is a vowel?
Say the name out loud and listen for the vowel sound. If Y is doing the work of a vowel, count it as one. If it's doing the work of a consonant, count it there.
Take EMILY. Say it slowly: EM-i-LY. The Y at the end carries a clear vowel sound, an "ee." So in EMILY, the Y functions as a vowel and belongs with the Soul Urge letters.
Now compare a name like YARA, where Y opens the word with a consonant push, "yah." There the Y is a consonant.
The test is always the sound, not the spelling. Trust your ear, and stay consistent once you decide.

Working SARAH from start to finish
Let's do a full name so you can see all three numbers appear.
SARAH: S, A, R, A, H.
Map each letter: S = 1, A = 1, R = 9, A = 1, H = 8.
The Expression (all letters) is 1 + 1 + 9 + 1 + 8 = 20. Reduce: 2 + 0 = 2.
Soul Urge (vowels): the vowels are A and A. That's 1 + 1 = 2. In this framework, the Soul Urge number 2 is tied to themes of connection, partnership, and sensitivity to others.
Personality (consonants): the consonants are S, R, and H. That's 1 + 9 + 8 = 18. Reduce: 1 + 8 = 9. The Personality is 9, often described as an outward impression of warmth and wide-hearted concern.
So SARAH, in this example, reads as a soul that wants closeness, meeting the world with a generous face. That's one possible interpretation among many, not a fixed statement about the real person.
The correction that matters most
Here's a mistake that can change a reading significantly. When you calculate the Expression, add the raw, unreduced totals of the vowels and consonants. Never add the already-reduced Soul Urge to the already-reduced Personality.
That shortcut can erase a master number that was really there.
Watch it happen with MICHAEL: M = 4, I = 9, C = 3, H = 8, A = 1, E = 5, L = 3. The raw sum is 4 + 9 + 3 + 8 + 1 + 5 + 3 = 33. That's a master number, 33/6. If you'd reduced the vowel and consonant groups first and then added the small results, you might have landed on plain 6 and never seen the 33.
Watch it again with DAVID: D = 4, A = 1, V = 4, I = 9, D = 4. The raw sum is 4 + 1 + 4 + 9 + 4 = 22, a master number, 22/4.
The shortcut fails in the other direction too. Go back to SARAH from earlier: her Soul Urge is 2 and her Personality is 9. Add those two reduced results the shortcut way, 2 + 9 = 11, and a master number appears that was never in the name. SARAH's real Expression, summed from the raw letters, is a plain 2. So the shortcut cuts both ways: with MICHAEL and DAVID it erases a master that is really there, and with SARAH it invents one that is not. Same error, opposite directions, on a name you have already worked by hand.
The Expression is where master numbers show up most often in this system, which is exactly where the shortcut costs the most. Always sum the raw letter values across the whole name first, then reduce, and hold any 11, 22, 33, or 44 you find.
What do the three planes mean together?
This method draws on the tradition, often associated with Pythagoras, of reading a person across three planes, and this is where the three numbers come together.
Vowels are Soul. They're the inner want, the thing that moves you when no one's watching. This is your Soul Urge.
Consonants are Body. They're the visible form, the way you land in a room. This is your Personality.
All letters are Spirit. The whole name read at once is the fuller current of who you are. This is your Expression.
The point isn't to read them separately and stop. A Soul Urge of 2 living inside an Expression of 33/6 suggests a different set of themes than a 2 inside a 5. Read them as one portrait: what you want, how you show up, and the larger pattern that holds both.
Treat these numbers as mirrors for reflection and self-exploration, not predictions. They describe possible tendencies and themes, not fixed or guaranteed outcomes, and they're not a substitute for medical, financial, legal, or psychological advice. If you want your full name and birth date read as one integrated picture, you can get your Soul Blueprint or shop readings.
A quick recap you can keep
Full birth name, first middle last. Map each letter with the table. Vowels give the Soul Urge, consonants give the Personality, every letter gives the Expression. Decide each Y by ear. Build the Expression from raw totals so you don't lose a master number. Then read all three together as one reflective portrait, not a prediction.
