One with your body

I'm not trying to be all spiritual, but I've been thinking a lot about being one with my body.  I'm not really sure how to explain what I am talking about.  Just that sometimes I feel like I don't know my body well enough and what it can and cannot do.  I do not know the limits of my body.  But it's not only that, it's like just feeling comfortable in my movements.  feeling that every movement, no matter how small, has a purpose.  and moving my body purposefully.  I want to learn my body and know it really well.  I want to feel comfortable in my body.  in my skin.  I don't think I am articulating this very well at all.  Maybe I need to process this concept more.  But I just have been thinking about it a lot.  Just having my mind and physical body be in sync.  Really knowing my body.  And listening to it.  I dunno, really.  But this concept has been floating around in my head for a bit.
