Walking to teach my morning vinyasa class, I was stopped in my tracks by this gorgeous metal support structure. Light pouring through parts of it, it's undulations, shapes, reflective nature and span was strikingly beautiful. Just half a block further on, there is another one of these -- so it isn't any one-of-a-kind marvel at all -- that is covered in all the next stages of building with no light in it, and few of its textures revealed. In a week's time, they will both be invisible above ceilings and below floors.
Class was all about this in a subtle way starting with slow rocking in the hip sockets to feel how the thigh bones seat and mindful rolling through the sitting bone supports, to reveal spinal support even as the weight shifts. Eventually we moved into standing sequences, unfolding and refolding with the breath, and allowing the hidden structures to do their work deep in the interior of each asana (posture). Yet their presence could still be established, felt, and explored.
