Tomas reflects on the idea that events that occur only once may hold little significance in the grand scheme of life. He contemplates the notion that if we experience something only a single time, it can feel as if it never truly happened. This perspective suggests a profound existential inquiry into the value of our experiences and choices.

The sentiment implies a deeper understanding of existence, where living only once might undermine the essence of life itself. Kundera evokes a philosophical struggle with the weight of our actions and moments, urging readers to consider the meaning behind their lived experiences and the fleeting nature of existence.
