I invite you to notice how each one of us adopts various attitudes, depending on the person or situation we have in front of us. We act in a certain way when we are in the presence of our parents, in another way when we are with our friends and yet differently when we talk to our boss. We change masks and roles all the time and we do this with extreme ease, almost mechanically. I'm not saying that this is necessarily bad, on the contrary it can be very convenient, but it becomes a problem when it happens without any awareness - which is the case of most of us. How conscious can we be in our interactions with others if this chameleon behaviour happens so automatically? At times, we slip even deeper into unconsciousness and we get stuck in one or two of those roles and we act according to what we think the proper reactions for that role should be (or rather we don't even think about them, we just act without any awareness).
Think about it for a moment and see how many of our (re)actions happen without any sense of logic or purpose. They happen just because we are used to reproduce them for many many years. They are those actions that give us an identity, a sense of self. The problem lies in the fact that many of those attitudes derive not from our own, conscious choices, but from the need to live up to the expectations of other people, be it our parents, our friends, the society in general. Trying to eliminate what we consider to be a negative aspect of the self can be very hard, as we soon realize that the Image has become an entity in itself, who will struggle to stay alive, no matter how malicious or destructive it may be.
Our reluctance to redetermine ourselves while life and situations shift around us and our attachment to that rigid sense of who we are, is the source of many personal disasters and dramas. And the ultimate (self) hypnosis.
