The Missing Piece is a famous poem by Shel Silverstein.

It’s about a circle with a missing piece. 

The circle goes searching, to no avail.

Finally it finds a piece that would seem to fit perfectly. 

The circle says, “I’m sure you don’t want to be my missing piece.”

The piece says, “I can be someone’s and still be mine.”

Oh yeah! 

Let’s meditate on that.
