Someone told me tonight about how "suppose" interferes with mindfulness. I think she was "right on." As I think "I'm suppose to be ..." my mind shifts from where I am to my parents (or teachers) kibitzing over my shoulder. I am no long lost in play (or work) but having second (and third) thoughts (inhibitions?).
It is no wonder that I hear these edicts. I was taught with a long list of "supposes." And yet to do anything with focus means not hearing those voices but plunging ahead.
I've noticed that when I'm sitting zazen, facing the wall, that a still shadow is in front of me cast from the light on the ceiling hitting my head. I see the shadow and know that it is from my body, but sense that the realizer is not in my body or in the shadow, but rather outside of both. As well, the realizer is not at a specific point in space, but surrounding me in the "ether." It is disorienting to not be where "I" am.
