The words "I," "My," and "Mine" are words given to us as children to define who we are. "I feel hungry." "My new toy." We've created our whole sense of self based off the material things that belong to us and the stature we think it gives us. "My Bugatti broke down and now I am very sad." But we don't get upset when "his" Bugatti breaks down.
The truth is that non of it matters because it's all conception. If Bugattis cost the same as ear buds then having one no longer creates stature. Who I am is not based on my possessions or my thoughts. If all those things disappeared I will still exist. Who I really am will not diminish.
Mama Ayahuasca made this very clear to me in one of my ceremonies. I realized that who I am is not based on my thoughts or anything I knew before. I am not skinny. I am not fat. I am not humble. I am not vengeful.
This whole idea of "I" is not a real thing because it changes everyday. This false idea of "I" is a preconception created by the ego and holds no weight for who we truly are. The true self is innocently sitting back and watching the ego create chaos. Check out Eckhart Tolle's book A NEW EARTH Awakening Your Life's Purpose for more detail. It's a great read!
