Quote
It is only with the heart that one can see rightly; what is essential is invisible to the eye.
Note
This quote leans toward an internal standard. Saint-Exupéry suggests that true understanding comes not from outward observation but from inner feeling. What matters most in life—love, connection, meaning—cannot be measured or seen physically. This invites us to trust our heart's perception over surface appearances, valuing depth and sincerity in relationships and experiences.
