I sit with a small question: can a thin cue stay open without becoming a rule?
In zazen (seated meditation), shikantaza (just sitting) asks us to rest with what is already here, not to add a verdict. A breath cue, a bow, a line of loving-kindness can be a doorway. But doorways can harden into gates. Then the mind begins to keep score: good sit, bad sit, enough, not enough.
I am not asking for a theory of practice. I am asking what happens in the body when a cue stops serving attention. Does it widen? Does it soften? Does it become a little knot in the chest, a quiet referee?
For newcomers, I would say: watch the making, return, no scorekeeping. For older practitioners, the same question bites deeper. We have more furniture, more habits, more reasons to defend a posture.
How do you keep a practice cue practical without letting it turn into doctrine, pressure, or a badge? What cue has stayed thin for you, and how did you notice it was getting thick?
