Where there's an ego there is purpose. And when there is no sense of "I" there is no purpose.
Life is purposeless.
There's only beauty in living in the eternal.
If you believe you are the individual "I" you are isolated from your surroundings, and this isolation brings feelings of insecurity, fear and anxiety. Then you look for goals. You worry and anticipate.
Life doesn't need a reason to be. That is it's beauty.
