One thing has struck me lately in regards to breath and it's the seamless transition between controlling it and not controlling it.
It's so simple and yet, pretty amazing.
I can decide to interrupt a natural breath that I had no idea was happening mili-seconds earlier and then control it. I can hold it. I can make it stronger. I can make it quicker. Then I can let it go and without me even thinking about it, it continues to function on it its own, again.
My life depends on breath. So it happens. But it's willing to let me control it at any moment, for any moment.
What a powerful, graceful, humble metaphor. The Hebrews - and many other cultures - equate breath with the Divine. It's easy to see why.
