The phrase "Everyone has his cross to bear" suggests that every individual faces their own struggles and hardships in life. This idea can resonate deeply in a world where challenges, responsibilities, and personal burdens vary from one person to another. It highlights the universal experience of suffering and the necessity of endurance in the face of life's difficulties.

In Franz Kafka's book "The Trial," this theme is especially relevant as the protagonist grapples with an absurd and incomprehensible legal system. Kafka illustrates how individuals confront their unique dilemmas, emphasizing that each person's fight may be different yet equally important. Ultimately, it points to the shared human condition of dealing with challenges and the inevitability of facing one's own burdens.
