People, including your own avatar, are projections of consciousness. They are not projections of your ego; your ego itself is a projection of consciousness as well.
Every human being is effectively a physical representation of part of the contents of consciousness. You are that consciousness, so every human being is a manifestation of a part of you. Consequently, everyone is significant and meaningful — there are no irrelevant or inconsequential people.
Every person you create in your reality is the manifestation of a thought. Every unique person represents a specific aspect of consciousness itself… a specific aspect of you. If you understand yourself fully, you will know all there is to know about people. And if you understand other people fully, you will know yourself completely.
