Your personality number in numerology is calculated using only the consonants in your full name. This is then followed by the same process of allocating a number to each letter before adding them up and breaking them down to get to a single digit number or master number.
The personality number is literally the side of you that you allow people to see. In turn this shows how others see you. What is true of most people is that we hide our true selves and therefore live under a persona. Sometimes this is done with great consideration. However, most of the time we do this without even realizing, or being entirely conscious of it. For that reason, it is often quite enlightening to see how your personality number can show the things that you ignore or don’t deal with by acting the way that you do. So, in turn, it can reveal deeper insights into your behaviors in different circumstances.
