The quote from Haruki Murakami's "Colorless Tsukuru Tazaki and His Years of Pilgrimage" emphasizes the importance of shared struggles in fostering deep connections between individuals. It suggests that true harmony is not solely achieved through joyful experiences, but rather through an understanding of each other's pain and vulnerabilities. Relationships are often forged in the fires of adversity, highlighting that emotional wounds can create a bond that is as strong as, if not stronger than, moments of happiness.
