Heaviness of Lightness

Light(ness)

"When we want to give expression to a dramatic situation in our lives, we tend to use metaphors of heaviness. We say that something has become a great burden to us. We either bear the burden or fail and go down with it, we struggle with it, win or lose. <...> Her drama was a drama not of heaviness but of lightness. What fell to her lot was not the burden but the unbearable lightness of being."  

Unbearable Lightness of Being, M. Kundera
