Each has his past shut in him like the leaves of a book known to him by heart and his friends can only read the title

Summary

This quote suggests that everyone carries their own personal history within them, much like the pages of a book. However, others can only perceive the surface level, represented by the title, while the individual themselves knows the full depth and intricacies of their past. It implies that one's true self and experiences are often hidden from others, who are only able to make assumptions based on limited information.
