The Chaldean system recognizes the same master numbers that were present in the Pythagorean system. These master numbers are 11, 22, and 33. The master numbers do not get reduced to single digits. In the Chaldean system, an individual's first name is their social persona and how they present themselves in public and the energy that comes with that. The first name also indicates the individual's personal interests and habits. The middle name is the soul energy and it reveals the truth about your inner soul and the deepest parts of yourself. The middle name shows the hidden talents, desires, and what your soul is trying to reach for. The last name is related to the domestic influence of the family.
