This whole world is made up of bits and pieces of things, who I really am is not a thing....(personal opinion, please talk to a qualified teacher)
A thing like this body is made up of millions of cells, billions of bacteria, bits and pieces of many things, what part of this is you? I don't think there is really any suffering or finding bliss and happiness, just the labeling of suffering and happiness...maybe there is no movement but what we observe as movement and grasping at that causes stress, but who is stressing? I haven't found anything solid or lasting in that flux, I am not a master just a student. This is something one will have to explore and discover on their own.
