I was made aware of this quite recently....

.....In some cultural traditions, buildings are deliberately left unfinished. Even if the entire structure is an intricate work of art, one little section is kept incomplete. This is a spiritual gesture, an acknowledgement of the idea that there's always room for improvement!

   

Nothing is ever as good as it can get. When we claim to have it all or pretend that we have solved all our problems, we are kidding ourselves. To be human is to wrestle with incompatible urges. Something in your world may be far from complete. Yet that doesn't mean it isn't still perfect in its own way.

Be as you wish to seem.   (Socrates)
