Put two or more spellings in and see every number side by side, with the arithmetic shown. This is the question name correction actually turns on, and it has an exact answer.
| Spelling | Total | Name number | Soul Urge | Personality | Change |
|---|---|---|---|---|---|
| Priya | 13 | 4 | 2 | 2 | baseline |
| Priyaa | 14 | 5 | 3 | 2 | +1, moves to 5 |
| Preeya | 22 | 4 | 2 | 2 | +9, still 4 |
Reducing a total to one digit is the same operation as taking its remainder on division by nine. So a spelling change moves your number by however much it adds, modulo nine — and a change that adds a multiple of nine leaves the number exactly where it was.
Take Priya, which totals 13 and reads 4. Priyaa adds 1, giving 14, so it reads 5 — one letter moved it one place. Preeya adds 9, giving 22, and reads 4 again: a bigger-looking change that moves nothing, because 9 is a multiple of nine.
That is the whole mechanism. It is also why only 73 of the 648 names in our corpus (11.3%) can be added to a first name without changing its number: almost nothing totals a multiple of nine.
A name carries three numbers and a spelling change does not move all of them. The full name number uses every letter, so it moves whenever anything changes. The Soul Urge uses only the vowels and the Personality only the consonants, so each of those moves only when its own half changes.
Add a vowel and you move two of the three: Priya reads 4 with Soul Urge 2 and Personality 2; Priyaa reads 5 with Soul Urge 3 and the same Personality 2.
Add a consonant and you move the other two: Priyal reads 7 with Personality 5 against 2, while the Soul Urge stays at 2.
So before paying for a correction, be clear which number it is meant to change. A change aimed at the full name number may leave the other two exactly where they were, and a practitioner who quotes you a new figure without saying which of the three it is has not told you much.
This is the part that surprises people. Because reducing is the same as taking a remainder on division by nine, a change that adds a multiple of nine leaves the number exactly where it was however many letters it involved. Preeya adds 9 to Priya — two letters changed — and still reads 4.
The reverse is also true: a single letter worth 1 moves the number one place, which is why corrections so often come down to doubling an A or adding an H. It is not that small changes are preferred. It is that a change of 1 is the smallest thing that is guaranteed to move the answer.
The same arithmetic explains surnames. Only 73 of the 648 names in our corpus — 11.3% — total a multiple of nine, so adding almost any second word changes the number, and your full name and your first name usually read differently.
Put in the spelling you use now first, then the variants you are considering. Read the full-name column to see which spellings land on a different number at all, and the Soul Urge and Personality columns to see what else moved with it.
Then stop, because the arithmetic has told you everything it can. Which of those numbers suits you is a question about your date of birth, not about the name — the tradition reads the name number against your Mulank, and a number that works for one birth date fights another.
We publish the friendship table we use on the methodology page, so you can do that step by hand too if you would rather not pay anyone. The name correction report does it for you and tests each spelling against both your Mulank and your Bhagyank.
The arithmetic tells you which spelling produces which number. It does not tell you that a different number will change your life, and nothing on this page is a reason to change a name you are happy with. A spelling nobody uses carries no vibration in the tradition's own terms, so a change only counts if you actually adopt it everywhere.
Because reducing a total to a single digit is the same as taking its remainder on division by nine. A change moves your number by however much it adds, modulo nine — so adding 1 moves it one place, and adding 9 or 18 moves it nowhere at all. That is the entire mechanism, and it is why most corrections are a single added or doubled letter.
Only if you changed a vowel. The Soul Urge uses the vowels and the Personality number uses the consonants, so adding a consonant leaves the Soul Urge exactly where it was and vice versa. The full name number moves either way, because it uses every letter.
No, and in the tradition's own terms a legal change is not the point. Chaldean reads a name as a sound that gets repeated, so what matters is the spelling you actually use and answer to. A spelling that exists only on a certificate carries less weight than the one people say, and a spelling nobody uses carries none.
That depends on your date of birth, not on the name alone — the tradition reads the name number against your Mulank, and a name that suits one birth number does not suit another. This tool shows you what each spelling produces. Choosing between them is what the name correction report does.
