You are the entity that observes: Your thoughts, your feelings, your mental health and diagnosis', your physical body, sensations, touch and the world.
Blew my mind to realise I am not my thoughts, I'm the entity that observes my thoughts. Because I feel like my thoughts. Yk. But I'm not!!
When I was younger I defined myself by the things I liked, and others similarly, you just start to see more depth and wisdom the more years you're lucky enough to kick around, in this planet, I think. And then you start to see, mostly the stuff people like is just funneled coping mechanisms. I can now tell you what peoples traumas are, by what they like. (lol)
