“And yet what they are looking for could be found in one single rose, or in a little water.”
“Yes, that is true,” I said.
And the little prince added:
“But the eyes are blind. One must look with the heart…” (25.16-19)
Most people are foolish, it seems. They go through life searching for something. And what is that thing? Well, the prince explains that this something “could be found in one single rose, or in a little water.” And a rose or some water is available anywhere. They are too available, almost, and so don’t seem special enough.
So, when people do see those things with their eyes, they “are blind.” The prince explains further that if people could look at these things “with the[ir] heart[s],” then they would be content and would have found what they were looking for. A piece of innocent wisdom from the little prince!
