" According to Freudian psychology, the ego is that part of us that allows us to correctly perceive external reality and function well in everyday life. People who have this concept of the ego frequently look upon the ego death as a frightening and tremendously negative event--as the loss of ability to operate in the world. However, what really dies in this process is that part of us that holds a basically paranoid view of ourselves and of the world around. Alan Watts called this aspect, which involves a sense of absolute separateness from everything else, "skin-encapsulated ego." It is made up of the internal perceptions of our lives that we learned during the struggle in the birth canal and during various painful encounters after birth. "
