Today the aspect of practice that I'm grateful for is the framework set by the practice, the boundaries. Note, I did not say I like them, just that I am grateful for them.
I know that one of the reasons for the depth of understanding that I've gained from this practice is that I made an agreement to work within the boundaries of the practice. The depth comes from the the compromises I make when I bump up against the edges of the framework. It's uncomfortable and I sometimes don't like it, but I am grateful for it.
I think it's important that I've made that choice voluntarily. No one makes me do the poses in order. There are no yoga police to make trouble if I only do the ones I like. If I did whatever I wanted, I would inevitably do what is comfortable, what feels good, and what I'm "good" at. I would not be challenged and I wouldn't grow.
I'm aware now that so much more is possible than I ever imagined....but those possibilities are only there because I submitted to the practice, boundaries included.
Part of that process of submission for me has been learning to set the boundaries intelligently, feeling out where not to be so rigid and where to keep on doing the bits that are uncomfortable, when I'd rather not. This is a process for a lifetime and I expect it to keep evolving as long as I keep practicing.
