It is obviously important for me to be aware of this room, or any other box I find myself in, but I would be a fool to rely upon it. Not because it is in any way unreliable, but because when I rely upon something, part of my energy is with that thing in the wrong way – in a way that weakens me. The sadness that goes with any real spiritual work is simply the realisation that ultimately you are alone, and it is you your energy should coil around, not anything external to you. Eventually, once those coils have really tightened, this sadness becomes the warrior's joy.
