How do you identify? Is it just your ego? Do you identify only as a solo human being?
Isn’t there much more than that?
You also belong to a biological family. You have other characteristics that can bind you to other groups; be it gender or the color of your skin.
You also exist in a community which is part of a larger political organization be it a city, county, State or Nation. Take it one step further, of the planet, of the universe!
So how you identify is based solely on how your ego limits your identity. You might think that it expands your identity, but you would be wrong.
As you identify with each particular group, don’t you also acquire certain beliefs associated with that group? Boy, that can add up to a lot different identities. It takes a lot of energy to maintain that distinction, doesn’t it?
How would your behavior change if you only saw yourself as part of the universe? Wouldn’t you see every other being, lifeform, or element of nature as part of your family?
