Neuveritelna Lehkost Byti - Kundera

If every second of our life recurs and infinite number of times, we are nailed to eternity...terryfying prospect...unbearable responsibility lies heavy on every move we make...eternal return "das schwerste Gewicht"...If eternal return is the heaviest of burdens, then our lives can stand out against it in all their splendid lightness...But is lightness truly splendid?
The heaviest of burdens is therefore simultaneously an image of life's most intense fulfiullment...Conversely, the absolute absence of burden causes man to be lighter than air...become only half real, his movements are as free as they are insignificant.
What shall we choose?

Weight or lightness?
