Ego is a myth
Ego is the false identity. We create two identities one is outer identity called ahankaar which we project to the outer world as who we want the outer world, society to believe about us. The other identity is the inner identity or mamakaar which we project to ourselves thinking or believe what we really are. Both these identities are pure lies or call them impure lies. Both these identities are a set of ideas, concepts related to societal behavior, morality, qualifications, possessions, name, fame, status, etc. All of these are external and temporary and are created by set of other minds which are once again under some false beliefs about true identity.
Seriousness is nothing but trying to constantly create, maintain and chisel and protect these two identities. Seriousness kills spontaneity and never allows the true self to express instead we are constantly trying to maintain the mind and its concepts. Ego manifests itself in so many ways and we live according to it every minute of our lives. We all actually use masks in our day-to-day lives. We use one mask when we deal with our parents, one with our subordinates, one with our bosses. As long as you know 'who are you for you', as long as you use the right mask for the right persons, it is alright. You can enjoy only when you know that you are something beyond the mask. But ego itself manifests in so many cunning ways, it makes you cling to all these masks and makes you believe that it is your true identity.
Active Ego and Passive Ego
Some people have active ego and some of them have passive ego. Active ego is very easy to recognize. Active ego will not be willing to let go of it even if all his other defenses like money, wealth, etc are taken away from him. But passive ego is very subtle and cunning. People who have passive ego will pose to be very humble, lacking courage to face people, shying away from taking credit, etc. The worst part of this is they are like this because they are not egoistic. The truth is they are more egoistic than the other lot. They are so carefully guarding their ego from getting hurt by doing all these humble things. When you are in deep awareness and understanding you will be a mere watcher of your ego and in this state you will automatically be neither humble nor egoistic, you will neither take credit nor shy away from it. And you will not even think or claim that you are neither of these. You simply will be, that's all. When anyone appreciates you or gives you credit, you will simply resonate with Existence and leave it at that, that's all. And there will be no need for any comparison or claim. You care so much for other's reactions and opinions towards you. You cannot bear to suffer a dent on your ego that you have nurtured so carefully all these years. This ego is your very anchor point. If that is jolted, you will feel anchorless.
