Many numerologists use four or five core numbers. I use six. These numbers are the most important part of a numerology chart. They give you and your numerologist an overview of who you are. As each numerologist has his or her own names for most of these numbers, I will also give the method I use to find each number.
Self-expression (all of the letters in your name): This number describes how you usually relate to the world. It includes many abilities as well as personality traits. For instance, a 5 self-expression indicates the ability to handle sudden changes, as well as the trait of having a variety of interests.
Personality (the consonants in your name): This number describes how other people tend to see you. Quite often, the client who is receiving the report looks at the reading associated with this number and says, "I'm not like that!" However, that client's friends and family will think that it describes the client very well. For instance, a 1 personality will be seen as a leader, and will often find themselves having to take on leadership roles whether they want to or not.
Soul (the vowels in your name): This number describes how you see yourself. Unless they are very close indeed, few of a client's friends will think that this number describes the client. However, the client will see it as a very good description of himself or herself. For instance, a 4 soul will be very good at dealing with detailed tasks.
Life Path (your full birthdate): This number indicates the area in which you are likely to do most of your work, whether it is for money or not. Abilities are often described with this number. For instance, a 6 life path is likely to become a nurse or a teacher - or be perfectly happy as a stay-at-home parent. The 6 gives the person the abilities necessary to do well in such roles.
Birthday (the day of your birth - not the month or the year): This number indicates abilities that you will develop in your late 20s or early 30s. Quite often, these abilities are picked up as hobbies. For instance, someone with an 8 birthday is likely to pick up practical skills, such as handicrafts, that could result in greater funds or status.
Maturity (your full name plus your full birthdate): This number indicates the goal you are working towards. You could consider it your destiny. This number does not usually take full effect until the client is in his or her 60s. For instance, someone with a 2 maturity is likely to find himself or herself working with others on a regular basis during his or her senior years.
Obviously, these are very brief descriptions. I usually write at least a third of a page of description for each of these numbers in one of my reports. However, this brief version should give you a general idea of what you should expect in any numerology report.
