Progress Through Complacency? What?

One thing that I am currently re-discovering is still confusing me.

I am in a second period of low yoga activity; I'm not doing a whole lot of it. I found that there are a couple of postures that I'm able to engage more deeply that I had been when I was doing yoga three-to-five times a week. This confuses me. This runs completely counter to my work ethic and the idea that progress is the payoff for work. Instead, I find occasionally that not-working has delivered progress that I have sought.

I'm trying to wrap my head around the idea that not-working on something yields progress where working on something did not. I'm not entirely comfortable with this. My immediate, deeply ingrained response is that by being lazy, something can be accomplished? That hardly seems logical or fair.

Of course I should look at the discovery, accept it, and move onward, but I do not like to accept something without a satisfactory understanding of it. I don't like not-understanding.
