The Listening Path, 39th Day of Spring, 525 M.E. (Deneb): Between our chattering mind and our recognition of our chattering mind, a clearing opens. If we sit still and quiet our mind, we can observe the clearing. We can try to abide in that clearing, but as soon as we do, the chattering mind follows and the clearing vanishes.

Actually, it doesn't so much vanish as simply just reappear elsewhere. And when we go there, poof!, it's gone again.

As we observe the chattering mind, we become aware of a not-as-noisy, but still not-completely-silent mind that's observing the chattering mind. As we look at that quieter mind, we lose track of the chattering mind but once again we've become the observer. I wonder as this process repeats itself if it's a constant cycle of observer and the observer switching roles back and forth? The observer watching the observed, and then the observed watching the observer, repeated over and over? 

Or is it additive? The observer watching the observed, then another observer watching the first observer, and then a third observer, a fourth, a fifth, and so on infinitely?

You can lose your mind wondering these things but, in a manner, losing your mind may be the point of it all.
