Sentences

2. "You can only see things clearly with your heart. What is essential is invisible to the eye." (that is probably love)
3. "It is the time you have wasted on your rose that makes your rose so important." (that is why it is hard to let go)
4. "Whether it is a house, or stars, or the desert, what makes their beauty is invisible." (they say love is blind, or is it?)
