Of course different people fulfill different functions in this world. It cannot be otherwise. As far as intellectual or physical abilities are concerned—knowledge, skills, talents, and energy levels—human beings differ widely. What really matters is not what function you fulfill in this world, but whether you identify with your function to such an extent that it takes you over and becomes a role that you play. When you play roles, you are unconscious. When you catch yourself playing a role, that recognition creates a space between you and the role. It is the beginning of freedom from the role. When you are completely identified with a role, you confuse a pattern of behavior with who you are, and you take yourself very seriously. You also automatically assign roles to others that correspond to yours. For example, when you visit doctors who are totally identified with their role, to them you will not be a human being but a patient or a case history.
