The narcissist drains himself of mental energy in this process. This is why he has none left to dedicate to others. This fact, as well as his inability to love human beings in their many dimensions and facets, ultimately transform him into a recluse. His soul is fortified and in the solace of this fortification he guards its territory jealously and fiercely. He protects what he perceives to constitute his independence.

Why should people indulge the narcissist? And what is the "evolutionary", survival value of preferring one kind of love (directed at an image) to another (directed at one's self)?

These questions torment the narcissist. His convoluted mind comes up with the most elaborate contraptions in lieu of answers.

Why should people indulge the narcissist, divert time and energy, give him attention, love and adulation? The narcissist's answer is simple: because he is entitled to it. He feels that he deserves whatever he succeeds to extract from others and much more. Actually, he feels betrayed, discriminated against and underprivileged because he believes that he is not being treated fairly, that he should get more than he does.

There is a discrepancy between his infinite certainty that his is a special status which renders him worthy of recurrent praise and adoration, replete with special benefits and prerogatives - and the actual state of his affairs. To the narcissist, this status of uniqueness is bestowed upon him not by virtue of his achievements, but merely because he exists.

The narcissist's deems his mere existence as sufficiently unique to warrant the kind of treatment that he expects to get from the world. Herein lies a paradox, which haunts the narcissist: he derives his sense of uniqueness from the very fact that he exists and he derives his sense of existence from his belief that he is unique.

Clinical data show that there is rarely any realistic basis for these grandiose notions of greatness and uniqueness.

Some narcissists are high achievers with proven track records. Some of them are pillars of their communities. Mostly, they are dynamic and successful. Still, they are ridiculously pompous and inflated personalities, bordering on the farcical and provoking resentment.

The narcissist is forced to use other people in order to feel that he exists. It is trough their eyes and through their behaviour that he obtains proof of his uniqueness and grandeur. He is a habitual "people-junkie". With time, he comes to regard those around him as mere instruments of gratification, as two-dimensional cartoon figures with negligible lines in the script of his magnificent life.

He becomes unscrupulous, never bothered by the constant exploitation of his milieu, indifferent to the consequences of his actions, the damage and the pain that he inflicts on others and even the social condemnation and sanctions that he often has to endure.

When a person persists in a dysfunctional, maladaptive or plain useless behaviour despite grave repercussions to himself and to others, we say that his acts are compulsive. The narcissist is compulsive in his pursuit of Narcissistic Supply. This linkage between narcissism and obsessive-compulsive disorders sheds light on the mechanisms of the narcissistic psyche.

The narcissist does not suffer from a faulty sense of causation. He is not oblivious to the likely outcomes of his actions and to the price he may have to pay. But he doesn't care.

A personality whose very existence is a derivative of its reflection in other people's minds is perilously dependent on these people's perceptions. They are the Source of Narcissistic Supply (NSS). Criticism and disapproval are interpreted as a sadistic withholding of said supply and as a direct threat to the narcissist's mental house of cards.

The narcissist lives in a world of all or nothing, of a constant "to be or not be". Every discussion that he holds, every glance of every passer-by reaffirms his existence or casts it in doubt. This is why the reactions of the narcissist seem so disproportionate: he reacts to what he perceives to be a danger to the very cohesion of his self. Thus, every minor disagreement with a Source of Narcissistic Supply - another person - is interpreted as a threat to the narcissist's very self-worth.

This is such a crucial matter, that the narcissist cannot take chances. He would rather be mistaken then remain without Narcissistic Supply. He would rather discern disapproval and unjustified criticism where there are none then face the consequences of being caught off-guard.

The narcissist has to condition his human environment to refrain from expressing criticism and disapproval of him or of his actions and decisions. He has to teach people around him that these provoke him into frightful fits of temper and rage attacks and turn him into a constantly cantankerous and irascible person. His exaggerated reactions constitute a punishment for their inconsiderateness and their ignorance of his true psychological state.

The narcissist blames others for his behaviour, accuses them of provoking him into his temper tantrums and believes firmly that "they" should be punished for their "misbehaviour". Apologies - unless accompanied by verbal or other humiliation - are not enough. The fuel of the narcissist's rage is spent mainly on vitriolic verbal send-offs directed at the (often imaginary) perpetrator of the (oft innocuous) offence.

The narcissist - wittingly or not - utilises people to buttress his self-image and to regulate his sense of self-worth. As long and in as much as they are instrumental in achieving these goals, he holds them in high regard, they are valuable to him. He sees them only through this lens. This is a result of his inability to love others: he lacks empathy, he thinks utility, and, thus, he reduces others to mere instruments.

If they cease to "function", if, no matter how inadvertently, they cause him to doubt his illusory, half-baked, self-esteem - they are subjected to a reign of terror. The narcissist then proceeds to hurt these "insubordinates". He belittles and humiliates them. He displays aggression and violence in myriad forms. His behaviour metamorphoses, kaleidoscopically, from over-valuing (idealising) the useful person - to a severe devaluation of same. The narcissist abhors, almost physiologically, people judged by him to be "useless".
