This is of great interest to me and I am forming an understanding for my "self-less" mind. I say "self-less" because according to Buddhist teachings, there is no true or absolute "self" that exist or is material. Here is the logic of what I understand: Where does self live? In the brain? When the brain dies, where is the "self?" Is the "self" in body cells? When cells die, where is this "self?" Awareness is a byproduct of brain, mind--a function of the brain and/or mental components, and our five senses. But, when the brain dies, our mental components stop being. When the five senses stop being there is nothing to perceive or sense. Awareness will then cease. So, where is the self? Self is not a single component of the brain, sense organs, mental components (feelings, personality, emotions, cognition) because the body dies and everything with it--except maybe energy (atoms). Is energy "self?" Energy does not have a brain, mind, material body, sense organs--as we know it. Energy cannot be created or destroyed, it comes in different forms, and can be either stored (in a form--e.g., body, mind, brain) or working (exerting to push, pull, move, create), but it is not the body, or mind, or mental components or sense organs in or of themselves. Energy is not aware and it does not have a "self" to speak of. It is not a single component of these factors. So, once we remove all of causes of body and mind, there is no awareness or self that is independent and functioning on its own. That is how I understand the existence (or non-existance) of self, awareness and energy. I look forward to reading other ideas and thoughts.
