You've been living your whole life thinking that you're in control. The truth is that you're not in control. More exactly, there is no 'you' to be in control. Every action your body has taken and every thought that's risen in your mind has happened without anyone behind the curtains making it happen. Everything that's within your experience is entirely a product of past events. Just as your heart beats without anyone's approval, so your mind thinks without anyone's approval, and your body acts without anyone's approval.
