We all have an identity. We stand for something. This something when looked in a negative way is our ego. Ego is our defence which does not allow an attack on the identity. Anytime there is an attack on identity, ego feels hurt, and fights back with revenge. Ego has another negative trait - when you are successful it takes the form of arrogance.
Our identity is dear to us. Be prepared to feel naked, where you are without your identity. Then only your behaviour, manners, and culture will be your identity. This is your real self. Cultivate it. So, don't fear. Be prepared to lose your identity.
