It's funny you should mention that, Jim, because that's exactly what I experienced. For the umpteenth time, after reading M's words, I found myself wondering, "Hmm, what does that mean?" To know is to be fullfilled. "To know what?",  I wondered. "Hmmm..." It was then that my brain froze.

Mind you, this is a guy who says we should keep in touch for his clarity. But I think you've got it right. It's for the instant brain freeze. At least, that's what you get.

Never fails.
