Summary
This quote suggests that every object or being has a hidden side or aspect, symbolized by its shadow. It implies that nothing in existence can escape being accompanied by some form of darkness or negativity. In a broader sense, it may also imply that every action, decision, or person has both positive and negative consequences or qualities. Therefore, this quote serves as a reminder that even the seemingly innocuous or good-natured may have hidden flaws or consequences that we should be aware of.
