Further, or even before that, one finds many very dangerous effects in the expression of negative emotions.
The term 'negative emotions' means all emotions of violence or depression: self-pity, anger, suspicion, fear, annoyance, boredom, mistrust, jealousy and so on.
Ordinarily, one accepts this expression of negative emotions as quite natural and even necessary.
Very often people call it 'sincerity׳.
Of course it has nothing to do with sincerity; it is simply a sign of weakness in man, a sign of bad temper and of incapacity to keep his grievances to himself.
Man realises this when he tries to oppose it. And by this he learns another lesson.
He realises that in relation to mechanical manifestations it is not enough to observe them, it is necessary to resist them, because without resisting them one cannot observe them.
They happen so quickly, so habitually and so imperceptibly, that one cannot notice them if one does not make sufficient efforts to create obstacles for them.
