Your Outer Number represents how "others see you". Because it is a reflection of how others tend to see you it can help you to identify some of your talents, characteristics, strengths and weaknesses. We're often blind to our own power and greatness. The information that the Outer Number can provide gives us an understanding of how others may attempt to communicate, connect with and guide us.
Your Outer Number can also reflect the "first impression" that you give to others. As you mature other personality factors can play a role as well. However, this number can help you to better understand how people perceive you and may offer you some guidance on how best to initially connect with others.
Numerology can show you what others may see in you through your Outer Self, but then part of your work is to recognize when the "outer self" may be a projection of what "others" hope, expect, and maybe even fear of us. Some of these impressions can be true, while some can be projections of the cast-off elements of others personalities, fears, and dreams. This is not to say that the number is a negative one, but one in which we all can have some issues.
Your Outer Number can represent some of your unrecognized strengths, weaknesses, skills, and potential. It may even describe a social mask you use to protect yourself. You may even wish to compare the Outer number with your Soul Number, as they may offer conflicting descriptions of your personality. This "point of conflict" can be important for you to understand, as it can provide vital information to your growth.
