i will put it simple because im feeling nervous
narcissism is na imbalance in the solar plexus chakra caused by shame
carried shame that has some pretty simple causes
humilhation, feeling dominated
abuse, neglect, feeling of being inadequate
it is a Strong feeling that you or other person have something wrong
our experiences arises from intention (karma) ,we are often not conscious of the result of our actions as we should be
the principal cause of shame is the intent to make others feel shame
what is the one principal charcteristic of an narcissist? is to shame others to feel empowered even if unconsciously, but this can never work because of karma
by taking from others you take from ourselves
so to eliminate narcissism , isn't it as simple as working on your own intent, and to let go of past experiences of shame and the emotion itself
abuse (can be too subtle to identify, without the awareness that experiences of shame through abuse can be subtle you know? the best tip is that generally, where there is abuse there is desire, and the fuel that keeps the abuse in the intent of people is this desire, an abuse can be called an act of stupidity, because it is the ignorance of the one that abuses that keeps him in an act that prejudices everyone)
let go of shame from past experiences where yours emotional , social and privative needs where violated
and to be aware of the intent you had on the past, like when you must have done the same on others
and just let go of shame, by making the choice of picking the best decision even for the others you might have abused or violated
so you can correct your past actions with good will
