Wish I could tell you what that was that brought it about but as so often with asana it seems to be a little shuffle here, slight rotation somewhere around there, a little bouncing in and out a bit on the edge, a smidgin more boldness perhaps......
What I 'think' happened is that I was perhaps a little deeper into the bend, feet felt nice and secure and balance felt good, stable. I used to think it was a case of getting my head down further, that getting my crown and then even the back of my head to the mat would help bring the shoulders further down. That didn't seem to bring my hands much closer though. I tended to focus on my hands, bouncing them towards the mat. This time I started thinking about the shoulders, bringing them down a little further, opening them up a little, almost drawing them apart to create a little more space. Also I didn't tilt my chin in right away but kept my head up a little to try and help bring the shoulders down. Once I was down as far as I felt could go I worked out from the shoulders playing around somewhat along the length of my arms. They felt closer to the mat, I bounced them in a little and felt the mat with my little finger. I came out, got the camera and tried the same thing again. This time I touched the mat three or four times and just about managed to rest part of my hand, fingers on the mat for a second or two.
Still a way to go of course to be able to rest my hands/arms comfortably on the mat but it looks like it's coming.
The fancy poses are nice, still enamoured by the shape of the Parsva Dandasana at the top of the blog behind the title, but it delights me when something improves a little in those old Standing and finishing postures that we've been doing everyday since we started. First time you get your head to the mat in the Parasaritas or grab toes in Badha padmasana and get your chin down in Yoga Mudra. Oh and your knees to the mat in Karna Pindasana or getting through Utthita hasta Padangusustasa sequence without bouncing back and forth all over your mat.
