"Watch what you're thinking. You don't know who's listening“, a friend of mine was told.  

Apparently, the person who said it knew what he was thinking, and possibly knew that he should Not be thinking it.  

I believe that all the answers are WithIn.  If we take a moment to LISTEN.  Though it may take more than a moment.  It may sometimes take a Lifetime, but I hope not that long for you and me.  

Stop and Listen.  Slow down.  Do Nothing.  Breath deeply.  Eat slowly.  Listen intently.

I’m sure we can all hear what each other is thinking.
