What your name says: expression, soul urge and personality numbers

Turning letters into numbers is not an invention of modern numerology. Letter-to-number tables appear in Heinrich Cornelius Agrippa's work printed in 1533, and long before that in the Hebrew gematria tradition, where each letter already carried a numerical value.

Three numbers, three questions

• Expression — from every letter of the full name. What you tend to build over a life.
• Soul urge — from the vowels alone. What you actually want, including what you do not say.
• Personality — from the consonants alone. The impression people form before they know you.

Splitting vowels from consonants sounds arbitrary, and to a degree it is. The traditional reasoning: vowels are produced from inside without being stopped by tongue or lips, so they stand for the inner part.

The problem with Vietnamese diacritics

The Pythagorean table has only the 26 Latin letters, so Vietnamese names have their diacritics stripped before conversion: Đ becomes D, Ơ becomes O, Ư becomes U. That is a convention, not a calculation — and it means the system was not designed for Vietnamese.

This site says so rather than hiding it, because that is the kind of detail that decides how far to trust a result. A system that loses information at its first step should not be read as a precise measurement.

When the three disagree

The most common and most interesting case: the personality and soul urge numbers are far apart. Read traditionally, that is someone whose outward impression does not match what they actually want — outwardly very composed, say, while inwardly restless for change.

You do not have to believe the arithmetic to find the question worth asking. How do other people see you, and how far is that from what you want? That is a good question wherever it came from.
