İf you identify yourself (your Self) with your feeling, perception, mental image of your body, consciousness (subjective awareness), in short, what is going inside your brain, it would mean that your self doesn’t exist, because it cannot control none of them. All of them are automatically controlled by your brain but not by your self. None of them are permanent, all are mutable. You cannot determine what to feel or how to perceive, your brain automatically does it for you, you cannot stop the change of your body image because of aging and you cannot control which part of information should be on conscious, which should be on unconscious level of your mind, considering that more than 90% of all information is hidden from your conscious mind and you are simply not aware what is going inside your brain. That is why it is said that you are merely a bio-social robot without any self being capable of taking control of anything in your life. Your self can control almost nothing.
