Banging one's head against the wall is not the best way to go, clearly. But how and when do we know we are no longer being effective? How do we decide to make the call to stop, and take 10? Or even 1? The same can be said of our thoughts. How do we notice that they have run away with us or us with them? In order to come back, clear the cache, return to an open gentle awareness of space, there has to be this spark of consciousness - the one that notices we are on the wrong track and decides to take action. A mind within the mind. Or without.

so.
