Despair or enlightenment?

Zen masters speak of a point in one's practice when practice goes beyond just "practicing" and achieves a point where one stops trying. The desire to achieve, to be enlightened and to not fail all melt away to be left with a buddha-nature. Some speak of it in a way where you're faced with so much frustration with the illusions that the mind creates that the mind kinda implodes. Or so I've gathered...

The last 72 hours have been a nonstop "GO!" mode for me where last night culminated in a melt down. What have I been doing? Meditating? Practicing? Climbing? I wish - I'm faced with an impossible task of proving my PI right in a statement he made to some colloborators. These collaborators happen to control a sizeable chunk of money (probably millions) of dollars that funds my paycheck, along with half a dozen other people's paychecks. I need to prove my PI right, otherwise that flow of money may trickle. Stressful.

On top of just completing that task, I've had problems at work - everything from network harddrives failing on me, to 2 minute automated tasks turning into 5 hours of manual work for me.

Further on top of that, the lease on our old place ended today - Steph, Taryn and I had to completely move out AND clean the place enough so that we can just wash the carpets this morning (which we ended up being successful). Last night, I started work at 7:15 am, left work at 8 pm and cleaned from 8:30 till 12 am.

At the end of it all, I slumped against a corner, sat down and shut down. My mind and body was numb from being stressed, having an adrenaline high and forcing myself to keep going without question. All internal monologues shut down, my mind was quiet and nothing but sitting remained.

I woke up this morning after 6 hours of sleep feeling more refreshed than I have in a couple of weeks. Was what I experienced last night satori, a minor enlightenment, that Masters speak of? Have I glimpsed the ox as the ancient masters used to say?

More likely it was me, going to sleep while so utterly exhausted that I didn't stress if I have a job or not in a few weeks... Babies never slept better.
