A Soul Urge Number is calculated using only the vowels in a person's full birth name, believed to reveal inner desires and motivations, the things a person wants most deeply, even if they don't openly express them. It's considered a more private counterpart to the Destiny Number, which reflects outward talents rather than inner longing.

How to calculate it:
Using the same letter-to-number chart as the Destiny Number, add only the vowels (A, E, I, O, U) found in the full birth name, then reduce to a single digit.

Example — Name: Emma Rose Carter

Vowels present: E, A, O, E, A, E
Values: 5 + 1 + 6 + 5 + 1 + 5 = 23
Final reduction: 2 + 3 = 5

Soul Urge Number: 5
