" “I will fly to those royal birds,” he exclaimed, “and they will kill me, because I am so ugly, and dare to approach them; but it does not matter: better be killed by them than pecked by the ducks, beaten by the hens, pushed about by the maiden who feeds the poultry, or starved with hunger in the winter.”
Then he flew to the water, and swam towards the beautiful swans. The moment they espied the stranger, they rushed to meet him with outstretched wings.
“Kill me,” said the poor bird; and he bent his head down to the surface of the water, and awaited death.
But what did he see in the clear stream below? His own image; no longer a dark, gray bird, ugly and disagreeable to look at, but a graceful and beautiful swan. To be born in a duck’s nest, in a farmyard, is of no consequence to a bird, if it is hatched from a swan’s egg. He now felt glad at having suffered sorrow and trouble, because it enabled him to enjoy so much better all the pleasure and happiness around him; for the great swans swam round the new-comer, and stroked his neck with their beaks, as a welcome.

“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. And Sabina - what had come over her? Nothing. She had left a man because she felt like leaving him. Had he persecuted her? Had he tried to take revenge on her? No. 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.” ― Milan Kundera, The Unbearable Lightness of Being
