Genkaku made an interesting post this morning that I think highlights the way many of us obsess about what we perceive as "bad," but seem to forget the impact of what we perceive as "good."
Your good habits will come back to haunt you and require a hard, sometimes hellacious, effort to clarify. This is not just some sissified theory or philosophy.
Habits by their nature leave traces and shadows. Bad habits, good habits ... traces and shadows remain.
Seems to me the operative word here is "habits." I'm reminded of my yoga teacher's frequent comments about "choosing the path of least resistance" and how, that might be the easiest way, but what does it teach us? He often comes up with new approaches to age-old yoga poses, and I think this is in part because he's witnessed how all of us, himself included, get stale and mindless about our lives. I'm also reminded of the times we have changed the translations of chants at our zen center, and how, in both situations, we're offered the opportunity to hang with the confusion, irritation, and not knowing that arises.
I don't think the above means we have to toss out positive habits. But maybe it's an invitation to break the groove, any groove, at least once in a while. Isn't that what Buddha taught us when he said the teachings are to be let go of once we cross the river?
