The quote illustrates that the most profound sadness doesn't always manifest externally. While visible tears and outward displays of grief can be recognized by others, the deepest sorrow often remains hidden within. This inner anguish is more damaging, as it cannot be easily soothed or addressed, leading to lasting scars on the emotional and spiritual self.
This internal suffering leaves an individual feeling vulnerable and isolated, unable to share their pain or find solace. The scars symbolize not just past hurt but also a part of the soul that has diminished due to these unexpressed emotions, highlighting the complexity of grief and healing in one's life.
