The remnants of pain left behind by every strong negative emotion that is not fully faced, accepted, and then let go of join together to form an energy field that lives in the very cells of your body.

Thinking is compulsive: you can't stop, or so it seems. It is also addictive: you don't even want to stop, at least not until the suffering generated by the continuous mental noise becomes unbearable.

You are not just a meaningless fragment in an alien universe, briefly suspended between life and death, allowed a few short-lived pleasures followed by pain and ultimate annihilation.

Strictly speaking, "you" cannot become enlightened, because who you take yourself to be is like a ripple in the ocean of consciousness - or a little wave if you're a VIP - and the ripple doesn't become enlightened until it realizes that its ripple-identity is ultimately a misperception, that it is the ocean taking on a fleeting ripple-form.

Fear seems to have many causes. Fear of loss, fear of failure, fear of being hurt, and so on, but ultimately all fear is the ego's fear of death, of annihilation. To the ego, death is always just around the corner. In this mind-identified state, fear of death affects every aspect of your life.

If you identify with a mental position, then if you are wrong, your mind-based sense of self is seriously threatened with annihilation. So you as the ego cannot afford to be wrong. To be wrong is to die. Wars have been fought over this, and countless relationships have broken down.

Through being "right", you feel superior and through feeling superior you strengthen your sense of self. In reality, of course, you are only strengthening the illusion of ego.
