english: It means that after a trauma, without question, we lose our "unbearable lightness of being," that sense of immortality that keeps us here -- meaning, if we're here, we almost feel like we're immortal, which we're not, but if we didn't believe that, we'd say, "What's the point of it all?"
non_english: Znači da nakon traume, bez pitanja, gubimo svoju "nepodnošljivu lakoću postojanja", taj osećaj besmrtnosti koji nas održava ovde - znači, ako smo ovde, osećamo se skoro kao da smo besmrtni, a nismo, ali ako ne bismo verovali u to, rekli bismo: "Koji je smisao svega?"
