The quote suggests that every individual possesses a hidden part of themselves, a secluded area that they guard closely. This inner space resembles a fortress, symbolizing the personal and intimate aspects of one’s identity. It represents the core of who we are, encompassing our true essence and individuality, distinct from everyone else.

This private part of ourselves can be understood as either our soul or simply the unique attributes that define us. It emphasizes the idea that, while we may share many experiences and interactions, there remains an essential element of privacy within each person, contributing to the richness of human existence.
