We are all like the bright moon, we still have our darker side.

The image of the “bright moon” paired with its “darker side” frames human character as inherently mixed: even those who appear luminous—virtuous, accomplished, or serene—retain hidden flaws, pain, or moral ambiguity. The metaphor suggests that darkness is not an exception but a structural part of wholeness, just as the moon’s shadowed face is inseparable from its glow. Read this way, the line encourages humility (recognizing one’s own limits) and compassion (granting others complexity rather than demanding purity). It also implies that self-knowledge involves acknowledging what is concealed, not merely performing brightness for the world.
