In the case of envy, as it results from many specialized sources, we are dealing with an extremely pernicious phenomenon. Regardless of how it is approached - as "an unpleasant state, along with shame and guilt, causing difficulties of psychological regulation and social adaptation," as "an ensemble of simpler emotional reactions, in various proportions and combinations (such as hostility, feelings of inferiority and injustice), or as something that conveys the expression of "emotional constructs associated” with “a significant specific weight" (like the state of jealousy, hope or schadenfreude) - each time it appears as a complex social emotion centered around "the desire to acquire the attributes or things that another person possesses". In uttering the word envy, we refer to the "selfish feeling of sorrow, tribulation, oddness, caused by the successes or the good situation of another", to a "tumultuous and obsessive state caused by the awareness of the fact that for the moment, we do not possess what one possesses, "or “an inner plague, through which the sadistic pleasure of talking bad about our friends, of criticizing the qualities of our acquaintances and defaming the beloved of another, insinuating that he/she is unfaithful, is constantly appearing". The passion that unleashes at last stays unconfessed because, in fact, "it is impossible to confess it". Envy is "mostly silent," but "always active," being implied in a hidden way “in the judgments and choices of those we come in contact with". Following, to a certain extent, R. Descartes, we could say that any one of those who surrender to envy sooner or later display an "earthly face" caused by the circulation of a "vicious" blood, and a "black yellowish"gallbladder. As soon as a certain sense of control is put on envy, the life of each of the individuals who were not so long ago characterized by the inability to enjoy the success of others starts to radically change, knowing a new measure and a new beginning. Once out of the unlimited influence of the "neighbor’s goat" syndrome, these individuals realize that they have a healthy way of building constructive relationships, with a mentality of solidarity and "being" instead of "having".
