What is essential is invisible to the eye?

"Essential is invisible to the eye" is a famous quote from the book "The Little Prince" by Antoine de Saint-Exupéry. The quote suggests that things that are truly important cannot be seen with the naked eye, but can only be understood through deeper knowledge and connections. This idea emphasizes the importance of inner values, emotions, and relationships over material possessions and appearances. It also encourages individuals to look beyond surface-level characteristics and deepen their understanding of themselves and others. Overall, the quote suggests that true essential qualities, such as love, kindness, and compassion, are intangible and can only be experienced through inner reflection and empathetic connections.
