In Milan Kundera's "The Unbearable Lightness of Being," the notion of necessity is explored, suggesting that it often lacks predetermined solutions or formulas. Instead, it thrives on the unpredictable nature of chance, implying that life develops through random occurrences rather than a set path. This perspective emphasizes the role of fate and serendipity in shaping experiences.

The quote further delves into the concept of memorable love, portraying it as a phenomenon that requires an abundance of fortunate events to flourish. Just as birds flock to the figure of Francis of Assisi, unforgettable love demands these chance encounters and moments that enrich its significance, highlighting the delicate interplay between love and the unpredictability of life.
