Both First Names Are 11

With traditional Pythagorean numerology, and if you know each other best as your first names, then it would mean you are likely to have many common characteristics recognized by the two of you. How likely and how many would depend on the names.

However, if you do not know each other best as your first names, then the energies tend to be diluted by the energy of the names you do know each other best as.

Other first name calculations are the cornerstone letter (the first letter of the name), the open heart letter (the first vowel of the name), and the capstone letter (the last letter of the name). Those all have an effect on the energy.
